+# Build Guide
+
+## Build Environment Setup
+
+### Windows (Vista and later)
+1. If you have ever installed WinAVR, uninstall it.
+2. Install [MHV AVR Tools](https://infernoembedded.com/sites/default/files/project/MHV_AVR_Tools_20131101.exe). Disable smatch, but **be sure to leave the option to add the tools to the PATH checked**.
+3. Install [MinGW](https://sourceforge.net/projects/mingw/files/Installer/mingw-get-setup.exe/download). During installation, uncheck the option to install a graphical user interface. **DO NOT change the default installation folder.** The scripts depend on the default location.
+4. Clone this repository. [This link will download it as a zip file, which you'll need to extract.](https://github.com/jackhumbert/qmk_firmware/archive/master.zip) Open the extracted folder in Windows Explorer.
+5. Double-click on the 1-setup-path-win batch script to run it. You'll need to accept a User Account Control prompt. Press the spacebar to dismiss the success message in the command prompt that pops up.
+6. Right-click on the 2-setup-environment-win batch script, select "Run as administrator", and accept the User Account Control prompt. This part may take a couple of minutes, and you'll need to approve a driver installation, but once it finishes, your environment is complete!
+7. Future build commands should be run from the standard Windows command prompt, which you can find by searching for "command prompt" from the start menu or start screen. Ignore the "MHV AVR Shell".
+
+### Mac
+If you're using [homebrew,](http://brew.sh/) you can use the following commands:
+
+    brew tap osx-cross/avr
+    brew install avr-libc
+    brew install dfu-programmer
+
+This is the recommended method. If you don't have homebrew, [install it!](http://brew.sh/) It's very much worth it for anyone who works in the command line.
+
+You can also try these instructions:
+
+1. Install Xcode from the App Store.
+2. Install the Command Line Tools from `Xcode->Preferences->Downloads`.
+3. Install [DFU-Programmer][dfu-prog].
+
+### Linux
+Install AVR GCC, AVR libc, and dfu-progammer with your favorite package manager.
+
+Debian/Ubuntu example: 
+
+    sudo apt-get update
+    sudo apt-get install gcc-avr avr-libc dfu-programmer
+
+### Vagrant
+If you have any problems building the firmware, you can try using a tool called Vagrant. It will set up a virtual computer with a known configuration that's ready-to-go for firmware building. OLKB does NOT host the files for this virtual computer. Details on how to set up Vagrant are in the [VAGRANT_GUIDE file](VAGRANT_GUIDE.md).
+
+## Verify Your Installation
+1. If you haven't already, obtain this repository ([https://github.com/jackhumbert/qmk_firmware](https://github.com/jackhumbert/qmk_firmware)). You can either download it as a zip file and extract it, or clone it using the command line tool git or the Github Desktop application. 
+2. Open up a terminal or command prompt and navigate to the qmk_firmware folder using the `cd` command. The command prompt will typically open to your home directory. If, for example, you cloned the repository to your Documents folder, then you would type `cd Documents/qmk_firmware`. If you extracted the file from a zip, then it may be named `qmk_firmware-master` instead. 
+3. To confirm that you're in the correct location, you can display the contents of your current folder using the `dir` command on Windows, or the `ls` command on Linux or Mac. You should see several files, including `README.md` and a `quantum` folder. From here, you need to navigate to the appropriate folder under `keyboard/`. For example, if you're building for a Planck, run `cd keyboard/planck`.
+4. Once you're in the correct keyboard-specific folder, run the `make` command. This should output a lot of information about the build process.
+
+## Customizing, Building, and Deploying Your Firmware
+
+Note: Some keyboard folders have non-standard organizations, and may not even support specifying alternate keymaps. Until these get reorganized, you will need to edit their default keymaps directly.
+
+1. Running the `make` command from your keyboard's folder will generate a .hex file based on the default keymap. All keymaps for a particular keyboard live in the `keymaps` folder in that keyboard's folder. To create your own keymap, duplicate the folder `keymaps/default`, and rename it with your name, for example `jack`. Or, if you don't care about the ability to share your keymap with the community via GitHub, you can just modify the default keymap itself. Details on how to program keymap files can be found in other guides. 
+2. To build a keymap other than the default, type `KEYMAP=<name>` after `make`. So if I've named my keymap `jack`, the full command would be `make KEYMAP=jack`.
+3. How you deploy the firmware will depend on whether you are using a PCB or a Teensy. In both cases, you'll need to put the keyboard in bootloader mode, either by pressing a button on the PCB/Teensy or pressing the key with the `RESET` keycode. Then, if you're using a PCB, just run `make KEYMAP=<name> dfu` to both build and deploy the firmware. If you're using a Teensy, you'll probably need to take the <keyboardname>.hex file that make produces in the keyboard's folder, and deploy it using the [Teensy Loader.](https://www.pjrc.com/teensy/loader.html)
+
+## Helpful Tips
+1. On Linux or OS X, you can run `sleep 5; make KEYMAP=<name> dfu` to delay building/deploying the firmware until for 5 seconds, giving you a chance to put the firmware into bootloader mode. You can change the 5 to any number of seconds.
+
+## Troubleshooting
+1. Try running `make clean` if the make command fails.

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+                            NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License along
+    with this program; if not, write to the Free Software Foundation, Inc.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+This guide was written step by step as I went through the process on a `Windows 10` `x86_64` and a `Windows 7` `amd k10` based system.  This should be generally applicable to to any `Windows` environment with `cygwin`.
+
+#####Do not skip steps. Do not move past a step until the previous step finishes successfully.
+
+Based on [avr-libc installation guide](http://www.nongnu.org/avr-libc/user-manual/install_tools.html)
+
+##Get the Required Packages
+Download the `cygwin` setup ([x86_64](https://cygwin.com/setup-x86_64.exe)) and install the default system plus the following if they are not already selected:
+- devel/git
+- devel/gcc-core
+- devel/gcc-g++
+- devel/flex
+- devel/bison
+- devel/make
+- devel/texinfo
+- devel/gettext-devel
+- devel/automake
+- devel/autoconfig
+- devel/libtool
+- text/gettext
+- libs/libgcc1
+- interpreters/m4
+- web/wget
+- archive/unzip
+
+The following sources will be required:
+- [gmp](https://gmplib.org/) (6.1.0)
+- [mpfr](http://www.mpfr.org/) (3.1.4)
+- [mpc](http://www.multiprecision.org/) (1.0.3) 
+- [binutils](https://www.sourceware.org/binutils/) (2.26)
+- [gcc](https://gcc.gnu.org/) (5.3.0)
+- [avr-libc](http://www.nongnu.org/avr-libc/) (2.0.0)
+
+The `dfu-programmer` will be required to flash the new firmware 
+- [dfu-programmer](https://dfu-programmer.github.io/) (0.7.2)
+
+The set of commands below will create a directory (`~/local/avr`) for the sources you compile to be installed on the machine and a directory (`~/src`) for these source files to be stored. The commands then download the sources of the needed packages and unpack them. Note: the expand commands are different depending on if the packages are offered as a `bz2` or `gz` archive
+```
+$ mkdir ~/local
+$ mkdir ~/local/avr
+$ mkdir ~/src
+$ cd ~/src
+$ wget https://gmplib.org/download/gmp/gmp-6.1.0.tar.bz2
+$ wget http://www.mpfr.org/mpfr-3.1.4/mpfr-3.1.4.tar.bz2
+$ wget ftp://ftp.gnu.org/gnu/mpc/mpc-1.0.3.tar.gz
+$ wget http://ftp.gnu.org/gnu/binutils/binutils-2.26.tar.gz
+$ wget http://mirror0.babylon.network/gcc/releases/gcc-5.3.0/gcc-5.3.0.tar.gz
+$ wget http://download.savannah.gnu.org/releases/avr-libc/avr-libc-2.0.0.tar.bz2
+$ tar -xjf gmp-6.1.0.tar.bz2
+$ tar -xjf mpfr-3.1.4.tar.bz2
+$ tar -zxf mpc-1.0.3.tar.gz
+$ tar -zxf binutils-2.26.tar.gz
+$ tar -zxf gcc-5.3.0.tar.gz
+$ tar -xjf avr-libc-2.0.0.tar.bz2 
+```
+
+##Setup the Build Environment
+These commands will set up the install directory and the `PATH` variable, which will allow you to access your installed packages.  Note: if you close the `cygwin` terminal window, you will need to rerun these commands, they are not permanent.
+```
+$ PREFIX=$HOME/local/avr
+$ export PREFIX
+$ PATH=/usr/local/bin:/usr/local/lib:/usr/local/include:/bin:/lib:/cygdrive/c/WINDOWS/system32:/cygdrive/c/WINDOWS
+$ PATH=$PATH:$PREFIX/bin:$PREFIX/lib
+$ export PATH
+```
+
+##The `gcc` Required Math Library Packages
+The following packages are required to be complied and installed in order to compile `gcc`.  They are not sufficiently available through the `cygwin` package system, so we have to make them ourselves.  They must be complied in this order because each one depends on the previous. Verfiy that for each package, `make check` returns all passing and no fails.
+
+###Build and Install `gmp`
+```
+$ cd ~/src/gmp-6.1.0
+$ ./configure --enable-static --disable-shared
+$ make
+$ make check
+$ make install
+```
+
+###Build and Install `mpfr`
+```
+$ cd ~/src/mpfr-3.1.4
+$ ./configure --with-gmp-build=../gmp-6.1.0 --enable-static --disable-shared
+$ make
+$ make check
+$ make install
+```
+
+###Build and Install `mpc`
+```
+$ cd ~/src/mpc-1.0.3
+$ ./configure --with-gmp=/usr/local --with-mpfr=/usr/local --enable-static --disable-shared
+$ make
+$ make check
+$ make install
+```
+
+##OPTIONAL Part
+You can build and install a brand new `gcc` or you can use the one supplied by `cygwin`.  This will take about 4-5 hours to compile (It is a "native build", so it does the entire build **3 times**. This takes a long while).
+
+###Build and Install `gcc` for Your Machine  
+```
+$ cd ~/src/gcc-5.3.0
+$ mkdir obj-local
+$ cd obj-local
+$ ../configure --enable-languages=c,c++ --with-gmp=/usr/local --with-mpfr=/usr/local --with-mpc=/usr/local --enable-static --disable-shared
+$ make
+$ make install
+```
+##End OPTIONAL Part
+
+###Build and Install `binutils` for Your Machine
+```
+$ cd ~/src/binutils-2.26
+$ mkdir obj-local
+$ cd obj-local
+$ ../configure
+$ make
+$ make install
+```
+
+##Buliding `binutils`, `gcc`, and `avr-libc` for the AVR system
+Now we can make the critical stuff for compiling our firmware: `binutils`, `gcc`, and `avr-libc` for the AVR architecture.  These allow us to build and manipulate the firmware for the keyboard.
+
+###Build `binutils` for AVR
+If you plan to build and install `avr-gdb` also, use the `gdb` install at the end of this guide as it also builds the `binutils`
+```
+$ cd ~/src/binutils-2.26
+$ mkdir obj-avr
+$ cd obj-avr
+$ ../configure --prefix=$PREFIX --target=avr --disable-nls
+$ make
+$ make install
+```
+
+###Build `gcc` for AVR
+```
+$ cd ~/src/gcc-5.3.0
+$ mkdir obj-avr
+$ cd obj-avr
+$ ../configure --prefix=$PREFIX --target=avr --enable-languages=c,c++ --with-gmp=/usr/local --with-mpfr=/usr/local --with-mpc=/usr/local --enable-static --disable-shared --disable-nls --disable-libssp --with-dwarf2
+$ make
+$ make install
+```
+
+###Build `avr-libc` for AVR
+For building the `avr-libc`, we have to specify the host build system.  In my case it is `x86_64-unknown-cygwin`. You can look for build system type in the `gcc` configure notes for the proper `--build` specification to pass when you configure `avr-libc`.
+```
+$ cd ~/src/avr-libc-2.0.0
+$ ./configure --prefix=$PREFIX --build=x86_64-unknown-cygwin --host=avr
+$ make
+$ make install
+```
+
+##Building 'dfu-programmer' for flashing the firmware via USB and installing the drivers
+We can either build our own, or use the precomplied binaries.  The precompiled binaries don't play well with `cygwin` so it is better to build them ourselves.  The procedure for the precompiled binaries is included at the end of this guide.
+
+### Build and Install the `libusb`
+The `dfu-programmer` requires `libusb` so that it can interact with the USB system. These repos must be bootstrapped in order to create an appropriate `./configure` and `Makefile` for your system.
+```
+$ cd ~/src
+$ git clone https://github.com/libusb/libusb.git
+$ cd libusb
+$ ./bootstrap.sh
+$ ./configure
+$ make
+$ make install
+```
+
+### Build and Install the `dfu-programmer`
+```
+$ cd ~/src
+$ git clone https://github.com/dfu-programmer/dfu-programmer.git
+$ cd dfu-programmer
+$ ./bootstrap.sh
+$ ./configure
+$ make
+$ make install
+```
+
+Verify the installation with:
+```
+$ which dfu-programmer
+/usr/local/bin/dfu-programmer
+
+$ dfu-programmer
+dfu-programmer 0.7.2
+https://github.com/dfu-programmer/dfu-programmer
+Type 'dfu-programmer --help'    for a list of commands
+     'dfu-programmer --targets' to list supported target devices
+```
+If you are not getting the above result, you will not be able to flash the firmware! 
+
+###Install the USB drivers
+The drivers are included in the windows binary version of [`dfu-programmer` 0.7.2](http://iweb.dl.sourceforge.net/project/dfu-programmer/dfu-programmer/0.7.2/dfu-programmer-win-0.7.2.zip).
+```
+$ cd ~/src
+$ wget http://iweb.dl.sourceforge.net/project/dfu-programmer/dfu-programmer/0.7.2/dfu-programmer-win-0.7.2.zip
+$ unzip dfu-programmer-win-0.7.2.zip -d dfu-programmer-win-0.7.2
+```
+
+or
+
+The official drivers are found in [Atmel's `FLIP` installer](http://www.atmel.com/images/Flip%20Installer%20-%203.4.7.112.exe). Download and then install `FLIP`. Upon installation, the drivers will be found in `C:\Program Files (x86)\Atmel\Flip 3.4.7\usb`.
+
+Then, from an **administrator-privileged** `Windows` terminal, run the following command (adjust the path for username, etc. as necessary) and accept the prompt that pops up:
+```
+C:\> pnputil -i -a C:\cygwin64\home\Kevin\src\dfu-programmer-win-0.7.2\dfu-prog-usb-1.2.2\atmel_usb_dfu.inf
+or
+C:\> pnputil -i -a "C:\Program Files (x86)\Atmel\Flip 3.4.7\usb\atmel_usb_dfu.inf"
+```
+
+This should be the result:
+```
+Microsoft PnP Utility
+
+Processing inf :            atmel_usb_dfu.inf
+Successfully installed the driver on a device on the system.
+Driver package added successfully.
+Published name :            oem104.inf
+
+
+Total attempted:              1
+Number successfully imported: 1
+```
+
+Alternatively, the `Windows` driver can be installed when prompted by `Windows` when the keyboard is attached. Do not let `Windows` search for a driver; specify the path to search for a driver and point it to the `atmel_usb_dfu.inf` file.
+
+##Building and Flashing the Planck firmware!
+If you did everything else right. This part should be a snap! Grab the latest sources from `github`, make the Plank firmware, then flash it.
+
+###Build Planck and Load the Firmware
+```
+$ cd ~/src
+$ git clone https://github.com/jackhumbert/qmk_firmware.git
+$ cd qmk_firmware/keyboard/planck
+$ make
+```
+
+Make sure there are no errors.  You should end up with this or something similar:
+```
+Creating load file for Flash: planck.hex
+avr-objcopy -O ihex -R .eeprom -R .fuse -R .lock -R .signature planck.elf planck.hex
+
+Creating load file for EEPROM: planck.eep
+avr-objcopy -j .eeprom --set-section-flags=.eeprom="alloc,load" \
+--change-section-lma .eeprom=0 --no-change-warnings -O ihex planck.elf planck.eep || exit 0
+
+Creating Extended Listing: planck.lss
+avr-objdump -h -S -z planck.elf > planck.lss
+
+Creating Symbol Table: planck.sym
+avr-nm -n planck.elf > planck.sym
+
+Size after:
+   text    data     bss     dec     hex filename
+  18602      82     155   18839    4997 planck.elf
+
+-------- end --------
+```
+
+If you do not get the above, you **did not** build the firmware, and you will have nothing to flash.  If you have the fresh clone from `github`, it was probably something gone wrong in this install process, go check and see what didn't work and threw errors or what steps you might have missed.
+
+But if everything went OK, you are ready to flash! Press the reset button on the bottom of the Planck, wait two seconds, then:
+```
+$ make dfu
+```
+.
+.
+.
+profit!!!
+
+
+
+
+
+##extra bits...
+
+###Installing Precompiled `dfu-programmer` Binaries (not recommended for `cygwin`)
+To install the `dfu-programmer` from the binaries, we must get if from [the `dfu-programmer` website](https://dfu-programmer.github.io/) ([0.7.2](http://iweb.dl.sourceforge.net/project/dfu-programmer/dfu-programmer/0.7.2/dfu-programmer-win-0.7.2.zip)).
+
+Copy this file into your `cygwin` home\src directory.  (For me, it is `C:\cygwin64\home\Kevin\src`), extract the files, move `dfu-programmer.exe` to `~/local/avr/bin`. Most obnoxiously, the `libusb0_x86.dll` and `libusb0.sys` need to be moved from  `./dfu-prog-usb-1.2.2/x86/` to a directory in the `Windows` `PATH` and the `cygwin` `PATH`. This is because the `dfu-programmer` binary is `mingw` based, not `cygwin` based, so the `dlls` do not cooperate. I achieved acceptable pathing by moving the files to  `C:\cygwin64\home\Kevin\local\avr\bin` Then, in a `WINDOWS` command prompt running (Adjusting your path for username, etc. as needed):
+```
+C:\> set PATH=%PATH%;C:\cygwin64\home\Kevin\local\avr\bin
+```
+
+Then, rename `libusb0_x86.dll` to `libusb0.dll`.
+ 
+You can tell that you were successful by trying to execute 'dfu-programmer' from the 'cygwin' prompt:
+```
+$ which dfu-programmer
+/home/Kevin/local/avr/bin/dfu-programmer
+
+$ dfu-programmer
+dfu-programmer 0.7.2
+https://github.com/dfu-programmer/dfu-programmer
+Type 'dfu-programmer --help'    for a list of commands
+     'dfu-programmer --targets' to list supported target devices
+```
+
+If you are not getting the above result, you will not be able to flash the firmware! 
+- Try making sure your `PATH` variables are set correctly for both `Windows` and `cygwin`. 
+- Make sure the `dll` is named correctly.
+- Do not extract it with `cygwin`'s `unzip` as it does not set the executable permission. If you did it anyway, do `chmod +x dfu-programmer.exe`.
+- Still have problems? Try building it instead.
+
+
+##Debugging Tools
+
+These tools are for debugging your firmware, etc. before flashing. Theoretically, it can save your memory from wearing out. However, these tool do not work 100% for the Planck firmware.
+
+### `gdb` for AVR
+`gdb` has a simulator for AVR but it does not support all instructions (like WDT), so it immediately crashes when running the Planck firmware (because `lufa.c` disables the WDT in the first few lines of execution). But it can still be useful in debugging example code and test cases, if you know how to use it.
+
+```
+$ cd ~/src
+$ git clone git://sourceware.org/git/binutils-gdb.git
+$ cd binutils-gdb
+$ mkdir obj-avr
+$ cd obj-avr
+$ ../configure --prefix=$PREFIX --target=avr --build=x86_64-unknown-cygwin --with-gmp=/usr/local --with-mpfr=/usr/local --with-mpc=/usr/local --disable-nls --enable-static
+$ make
+$ make install
+```
+
+### `simulavr`
+`simulavr` is an AVR simulator.  It runs the complied AVR elfs. `simulavr` does not support the `atmega32u4` device... it does `atmega32` but that is not good enough for the firmware (no PORTE and other things), so you cannot run the Planck firmware. I use it to simulate ideas I have for features in separate test projects.
+
+This one is a major pain in the butt because it has a lot of dependencies and it is buggy.  I will do my best to explain it but... it was hard to figure out. A few things need to be changed in the 'Makefile' to make it work in `cygwin`.
+
+
+```
+$ cd ~/src
+$ git clone https://github.com/Traumflug/simulavr.git
+$ cd simulavr
+$ ./bootstrap
+$ ./configure --prefix=$PREFIX --enable-static --disable-tcl --disable-doxygen-doc
+```
+ Edit `src/Makefile.am` now so that `-no-undefined` is included (I did this by removing the SYS_MINGW conditional surrounding `libsim_la_LDFLAGS += -no-undefined` and  `libsimulavr_la_LDFLAGS += -no-undefined \ libsimulavr_la_LIBADD += $(TCL_LIB)`. Also, `$(EXEEXT)` is added after `kbdgentables` in two places.
+
+```
+$ make
+$ make install
+```
+
+
+TODO:
+- git repos for all sources
+- command line magic for cygwin setup
+- better options for `dfu-drivers`

+# Quantum Hand-wiring Guide
+
+Parts list:
+* *x* keyswitches (MX, Matias, Gateron, etc)
+* *x* diodes
+* Keyboard plate (metal, plastic, cardboard, etc)
+* Wire (strained for wiring to the Teensy, anything for the rows/columns)
+* Soldering iron set at 600ºF or 315ºC (if temperature-controlled)
+* Resin-cored solder (leaded or lead-free)
+* Adequate ventilation/a fan
+* Tweezers (optional)
+* Wire cutters/snippers
+
+## How the matrix works (why we need diodes)
+
+The microcontroller (in this case, the Teensy 2.0) will be setup up via the firmware to send a logical 1 to the columns, one at a time, and read from the rows, all at once - this process is called matrix scanning. The matrix is a bunch of open switches that, by default, don't allow any current to pass through - the firmware will read this as no keys being pressed. As soon as you press one key down, the logical 1 that was coming from the column the keyswitch is attached to gets passed through the switch and to the corresponding row - check out the following 2x2 example:
+
+        Column 0 being scanned     Column 1 being scanned
+                  x                                   x
+                 col0     col1              col0     col1
+                  |        |                 |        |
+        row0 ---(key0)---(key1)    row0 ---(key0)---(key1)
+                  |        |                 |        |
+        row1 ---(key2)---(key3)    row1 ---(key2)---(key3)
+
+The `x` represents that the column/row associated has a value of 1, or is HIGH. Here, we see that no keys are being pressed, so no rows get an `x`. For one keyswitch, keep in mind that one side of the contacts is connected to its row, and the other, its column.
+
+When we press `key0`, `col0` gets connected to `row0`, so the values that the firmware receives for that row is `0b01` (the `0b` here means that this is a bit value, meaning all of the following digits are bits - 0 or 1 - and represent the keys in that column). We'll use this notation to show when a keyswitch has been pressed, to show that the column and row are being connected:
+
+        Column 0 being scanned     Column 1 being scanned
+                  x                                   x
+                 col0     col1              col0     col1
+                  |        |                 |        |
+      x row0 ---(-+-0)---(key1)    row0 ---(-+-0)---(key1)
+                  |        |                 |        |
+        row1 ---(key2)---(key3)    row1 ---(key2)---(key3)
+
+We can now see that `row0` has an `x`, so has the value of 1. As a whole, the data the firmware receives when `key0` is pressed is
+
+    col0: 0b01
+    col1: 0b00
+            │└row0
+            └row1
+
+A problem arises when you start pressing more than one key at a time. Looking at our matrix again, it should become pretty obvious:
+
+        Column 0 being scanned     Column 1 being scanned
+                  x                                   x
+                 col0     col1              col0     col1
+                  |        |                 |        |
+      x row0 ---(-+-0)---(-+-1)  x row0 ---(-+-0)---(-+-1)
+                  |        |                 |        |
+      x row1 ---(key2)---(-+-3)  x row1 ---(key2)---(-+-3)
+
+      Remember that this ^ is still connected to row1
+
+The data we get from that is:
+
+    col0: 0b11
+    col1: 0b11
+            │└row0
+            └row1
+
+Which isn't accurate, since we only have 3 keys pressed down, not all 4. This behavior is called ghosting, and only happens in odd scenarios like this, but can be much more common on a bigger keyboard. The way we can get around this is by placing a diode after the keyswitch, but before it connects to its row. A diode only allows current to pass through one way, which will protect our other columns/rows from being activated in the previous example. We'll represent a dioded matrix like this;

+        row1 ─────┴────────┘       row1 ─────┴────────┘
+
+In practical applications, the black line of the diode will be placed facing the row, and away from the keyswitch - the `!` in this case is the diode, where the gap represents the black line. A good way to remember this is to think of this symbol: `>|`
+
+Now when we press the three keys, invoking what would be a ghosting scenario:

+                  !        !                 !        !
+        row1 ─────┴────────┘     x row1 ─────┴────────┘
+
+Things act as they should! Which will get us the following data:
+
+    col0: 0b01
+    col1: 0b11
+            │└row0
+            └row1
+
+The firmware can then use this correct data to detect what it should do, and eventually, what signals it needs to send to the OS.
+
+## The actual hand-wiring
+
+### Getting things in place
+
+When starting this, you should have all of your stabilisers and keyswitches already installed (and optionally keycaps). If you're using a Cherry-type stabiliser (plate-mounted only, obviously), you'll need to install that before your keyswitches. If you're using Costar ones, you can installed them afterwards.
+
+To make things easier on yourself, make sure all of the keyswitches are oriented the same way (if they can be - not all layouts support this). Despite this, it's important to remember that the contacts on the keyswitches are completely symmetrical. We'll be using the keyswitch's left side contact for wiring the rows, and the right side one for wiring the columns.
+
+Get your soldering iron heated-up and collect the rest of the materials from the part list at the beginning of the guide. Place your keyboard so that the bottoms of the keyswitches are accessible - it may be a good idea to place it on a cloth to protect your keyswitches/keycaps.
+
+Before continuing, plan out where you're going to place your Teensy. If you're working with a board that has a large (6.25u) spacebar, it may be a good idea to place it in-between switches against the plate. Otherwise, you may want to trim some of the leads on the keyswitches where you plan on putting it - this will make it a little harder to solder the wire/diodes, but give you more room to place the Teensy.
+
+### Preparing the diodes
+
+It's a little easier to solder the diodes in place if you bend them at a 90º angle immediately after the black line - this will help to make sure you put them on the right way (direction matters), and in the correct position. The diodes will look like this when bent (with longer leads):
+
+       ┌─────┬─┐
+    ───┤     │ ├─┐
+       └─────┴─┘ │
+                 │
+
+We'll be using the long lead at the bent end to connect it to the elbow (bent part) of the next diode, creating the row.
+
+### Soldering the diodes
+
+Starting at the top-left switch, place the diode (with tweezers if you have them) on the switch so that the diode itself is vertically aligned, and the black line is facing toward you. The straight end of the diode should be touching the left contact on the switch, and the bent end should be facing to the right and resting on the switch there, like this:
+
+     │o
+    ┌┴┐         o
+    │ │    O
+    ├─┤      
+    └┬┘
+     └─────────────
+
+Letting the diode rest, grab your solder, and touch both it and the soldering iron to the left contact at the same time - the rosin in the solder should make it easy for the solder to flow over both the diode and the keyswitch contact. The diode may move a little, and if it does, carefully position it back it place by grabbing the bent end of the diode - the other end will become hot very quickly. If you find that it's moving too much, using needle-nose pliers of some sort may help to keep the diode still when soldering.
+
+The smoke that the rosin releases is harmful, so be careful not to breath it or get it in your eyes/face.
+
+After soldering things in place, it may be helpful to blow on the joint to push the smoke away from your face, and cool the solder quicker. You should see the solder develop a matte (not shiney) surface as it solidifies. Keep in mind that it will still be very hot afterwards, and will take a couple minutes to be cool to touch. Blow on it will accelerate this process.
+
+When the first diode is complete, the next one will need to be soldered to both the keyswitch, and the previous diode at the new elbow. That will look something like this:
+
+     │o               │o
+    ┌┴┐         o    ┌┴┐         o
+    │ │    O         │ │    O
+    ├─┤              ├─┤      
+    └┬┘              └┬┘
+     └────────────────┴─────────────
+
+After completing a row, use the wire cutters to trim the excess wire from the tops of the diodes, and from the right side on the final switch. This process will need to completed for each row you have.
+
+When all of the diodes are completely soldered, it's a good idea to quickly inspect each one to ensure that your solder joints are solid and sturdy - repairing things after this is possible, but more difficult.
+
+### Soldering the columns
+
+You'll have some options in the next process - it's a good idea to insulate the column wires (since the diodes aren't), but if you're careful enough, you can use exposed wires for the columns - it's not recommended, though. If you're using single-cored wire, stripping the plastic off of the whole wire and feeding it back on is probably the best option, but can be difficult depending on the size and materials. You'll want to leave parts of the wire exposed where you're going to be solder it onto the keyswitch.
+
+If you're using stranded wire, it's probably easiest to just use a lot of small wires to connect each keyswitch along the column. It's possible to use one and melt through the insulation, but this isn't recommended, will produce even more harmful fumes, and can ruin your soldering iron.
+
+Before beginning to solder, it helps to have your wire pre-bent (if using single-cored), or at least have an idea of how you're going to route the column (especially if you're making a staggered board). Where you go in particular doesn't matter too much, as we'll be basing our keymap definitions on how it was wired - just make sure every key in a particular row is in a unique column, and that they're in order from left to right.
+
+If you're not using any insulation, you can try to keep the column wires elevated, and solder them near the tips of the keyswitch contacts - if the wires are sturdy enough, they won't short out to the row wiring an diodes.
+
+### Wiring things to the Teensy
+
+Now that the matrix itself is complete, it's time to connect what you've done to the Teensy. You'll be needing the number of pins equal to your number of columns + your number of rows. There are some pins on the Teensy that are special, like D6 (the LED on the chip), or some of the UART, SPI, I2C, or PWM channels, but only avoid those if you're planning something in addition to a keyboard. If you're unsure about wanting to add something later, you should have enough pins in total to avoid a couple.
+
+The pins you'll absolutely have to avoid are: GND, VCC, AREF, and RST - all the others are usable and accessible in the firmware.
+
+Place the Teensy where you plan to put it - you'll have to cut wires to length in the next step, and you'll want to make sure they reach.
+
+Starting with the first column on the right side, measure out how much wire you'll need to connect it to the first pin on the Teensy - it helps to pick a side that you'll be able to work down, to keep the wires from overlapping too much. It may help to leave a little bit of slack so things aren't too tight. Cut the piece of wire, and solder it to the Teensy, and then the column - you can solder it anywhere along the column, but it may be easiest at the keyswitch. Just be sure the wire doesn't separate from the keyswitch when soldering.
+
+As you move from column to column, it'll be helpful to write the locations of the pins down. We'll use this data to setup the matrix in the future.
+
+When you're done with the columns, start with the rows in the same process, from top to bottom, and write them all down. Again, you can solder anywhere along the row, as long as it's after the diode - soldering before the diode (on the keyswitch side) will cause that row not to work.
+
+As you move along, be sure that the Teensy is staying in place - recutting and soldering the wires is a pain!
+
+### Getting some basic firmware set-up
+
+From here, you should have a working keyboard with the correct firmware. Before we attach the Teensy permanently to the keyboard, let's quickly get some firmware loaded onto the Teensy so we can test each keyswitch.
+
+To start out, download [the firmware](https://github.com/jackhumbert/qmk_firmware/) - we'll be using my (Jack's) fork of TMK called QMK/Quantum. We'll be doing a lot from the Terminal/command prompt, so get that open, along with a decent text editor like [Sublime Text](http://www.sublimetext.com/).
+
+The first thing we're going to do is create a new project using the script in the root directory of the firmware. In your terminal, run this command with `<project_name>` replaced by the name of your project - it'll need to be different from any other project in the `keyboard/` folder:
+
+    ./new_project.sh <project_name>
+
+You'll want to navigate to the `keyboard/<project_name>/` folder by typing, like the print-out from the script specifies:
+
+    cd keyboard/<project_name>
+
+#### config.h
+
+The first thing you're going to want to modify is the `config.h` file. Find `MATRIX_ROWS` and `MATRIX_COLS` and them to match the dimensions of your keyboard's matrix.
+
+Farther down are `MATRIX_ROW_PINS` and `MATRIX_COL_PINS`. Change their definitions to match how you wired up your matrix (looking from the top of the keyboard, the rows run top-to-bottom and the columns run left-to-right). Likewise, change the definition of `UNUSED_PINS` to match the pins you did not use (this will save power).
+
+#### \<project_name\>.h
+
+The next file you'll want to look at is `<project_name>.h`. You're going to want to rewrite the `KEYMAP` definition - the format and syntax here is extremely important, so pay attention to how things are setup. The first half of the definition are considered the arguments - this is the format that you'll be following in your keymap later on, so you'll want to have as many k*xy* variables here as you do keys. The second half is the part that the firmware actually looks at, and will contain gaps depending on how you wired your matrix.
+
+We'll dive into how this will work with the following example. Say we have a keyboard like this:
+
+    ┌───┬───┬───┐
+    │   │   │   │
+    ├───┴─┬─┴───┤
+    │     │     │
+    └─────┴─────┘
+
+This can be described by saying the top row is 3 1u keys, and the bottom row is 2 1.5u keys. The difference between the two rows is important, because the bottom row has an unused column spot (3 v 2). Let's say that this is how we wired the columns:
+
+    ┌───┬───┬───┐
+    │ ┋ │ ┋ │ ┋ │
+    ├─┋─┴─┬─┴─┋─┤
+    │ ┋   │   ┋ │
+    └─────┴─────┘
+
+The middle column is unused on the bottom row in this example. Our `KEYMAP` definition would look like this:
+
+    #define KEYMAP( \
+        k00, k01, k02, \
+          k10,  k11,   \
+    ) \
+    { \
+        { k00, k01,   k02 }, \
+        { k10, KC_NO, k11 }, \
+    }
+
+Notice how the top half is spaced to resemble our physical layout - this helps us understand which keys are associated with which columns. The bottom half uses the keycode `KC_NO` where there is no keyswitch wired in. It's easiest to keep the bottom half aligned in a grid to help us make sense of how the firmware actually sees the wiring.
+
+Let's say that instead, we wired our keyboard like this (a fair thing to do):
+
+    ┌───┬───┬───┐
+    │ ┋ │  ┋│ ┋ │
+    ├─┋─┴─┬┋┴───┤
+    │ ┋   │┋    │
+    └─────┴─────┘
+
+This would require our `KEYMAP` definition to look like this:
+
+    #define KEYMAP( \
+        k00, k01, k02, \
+          k10,  k11,   \
+    ) \
+    { \
+        { k00, k01, k02   }, \
+        { k10, k11, KC_NO }, \
+    }
+
+Notice how the `k11` and `KC_NO` switched places to represent the wiring, and the unused final column on the bottom row. Sometimes it'll make more sense to put a keyswitch on a particular column, but in the end, it won't matter, as long as all of them are accounted for. You can use this process to write out the `KEYMAP` for your entire keyboard - be sure to remember that your keyboard is actually backwards when looking at the underside of it.
+
+#### keymaps/default.c
+
+This is the actual keymap for your keyboard, and the main place you'll make changes as you perfect your layout. `default.c` is the file that gets pull by default when typing `make`, but you can make other files as well, and specify them by typing `make KEYMAP=<variant>`, which will pull `keymaps/<variant>.c`.
+
+The basis of a keymap is its layers - by default, layer 0 is active. You can activate other layers, the highest of which will be referenced first. Let's start with our base layer.
+
+Using our previous example, let's say we want to create the following layout:
+
+    ┌───┬───┬───┐
+    │ A │ 1 │ H │
+    ├───┴─┬─┴───┤
+    │ TAB │ SPC │
+    └─────┴─────┘
+
+This can be accomplished by using the following `keymaps` definition:
+
+    const uint16_t PROGMEM keymaps[][MATRIX_ROWS][MATRIX_COLS] = {
+    [0] = KEYMAP( /* Base */
+      KC_A,  KC_1,  KC_H, \
+        KC_TAB,  KC_SPC   \
+    ),
+    };
+
+Note that the layout of the keycodes is similar to the physical layout of our keyboard - this make it much easier to see what's going on. A lot of the keycodes should be fairly obvious, but for a full list of them, check out [tmk_code/doc/keycode.txt](https://github.com/jackhumbert/qmk_firmware/blob/master/tmk_core/doc/keycode.txt) - there are also a lot of aliases to condense your keymap file.
+
+It's also important to use the `KEYMAP` function we defined earlier - this is what allows the firmware to associate our intended readable keymap with the actual wiring.
+
+#### Compiling your firmware
+
+After you've written out your entire keymap, you're ready to get the firmware compiled and onto your Teensy. Before compiling, you'll need to get your [development environment set-up](https://github.com/jackhumbert/qmk_firmware/blob/master/keyboard/planck/PCB_GUIDE.md#setting-up-the-environment) - you can skip the dfu-programmer instructions, but you'll need to download and install the [Teensy Loader](https://www.pjrc.com/teensy/loader.html) to get the firmware on your Teensy.
+
+Once everything is installed, running `make` in the terminal should get you some output, and eventually a `<project_name>.hex` file in that folder. If you're having trouble with this step, see the end of the guide for the trouble-shooting section.
+
+Once you have your `<project_name>.hex` file, open up the Teensy loader application, and click the file icon. From here, navigate to your `QMK/keyboard/<project_name>/` folder, and select the `<project_name>.hex` file. Plug in your keyboard and press the button on the Teensy - you should see the LED on the device turn off once you do. The Teensy Loader app will change a little, and the buttons should be clickable - click the download button (down arrow), and then the reset button (right arrow), and your keyboard should be ready to go!
+
+#### Testing your firmware
+
+Carefully flip your keyboard over, open up a new text document, and try typing - you should get the characters that you put into your keymap. Test each key, and note the ones that aren't working. Here's a quick trouble-shooting guide for non-working keys:
+
+0. Flip the keyboard back over and short the keyswitch's contacts with a piece wire - this will eliminate the possibility of the keyswitch being bad and needing to be replaced.
+1. Check the solder points on the keyswitch - these need to be plump and whole. If you touch it with a moderate amount of force and it comes apart, it's not strong enough.
+2. Check the solder joints on the diode - if the diode is loose, part of your row may register, while the other may not.
+3. Check the solder joints on the columns - if your column wiring is loose, part or all of the column may not work.
+4. Check the solder joints on both sides of the wires going to/from the Teensy - the wires need to be fully soldered and connect to both sides.
+5. Check the <project_name>.h file for errors and incorrectly placed `KC_NO`s - if you're unsure where they should be, instead duplicate a k*xy* variable.
+6. Check to make sure you actually compiled the firmware and flashed the Teensy correctly. Unless you got error messages in the terminal, or a pop-up during flashing, you probably did everything correctly.
+
+If you've done all of these things, keep in mind that sometimes you might have had multiple things affecting the keyswitch, so it doesn't hurt to test the keyswitch by shorting it out at the end.
+
+#### Securing the Teensy, finishing your hardware, getting fancier firmware
+
+Now that you have a working board, it's time to get things in their permanent positions. I've often used liberal amounts of hot glue to secure and insulate things, so if that's your style, start spreading that stuff like butter. Otherwise, double-sided tape is always an elegant solution, and electrical tape is a distant second. Due to the nature of these builds, a lot of this part is up to you and how you planned (or didn't plan) things out.
+
+There are a lot of possibilities inside the firmware - check out the [README](https://github.com/jackhumbert/qmk_firmware/blob/master/README.md) for a full feature list, and dive into the different project (Planck, Ergodox EZ, etc) to see how people use all of them. You can always stop by [the OLKB subreddit for help!](http://reddit.com/r/olkb)

+
+## Setting up the environment
+
+### Windows
+1. Install [MHV AVR Tools](https://infernoembedded.com/sites/default/files/project/MHV_AVR_Tools_20131101.exe). Disable smatch, but **be sure to leave the option to add the tools to the PATH checked**.
+2. Install [MinGW](https://sourceforge.net/projects/mingw/files/Installer/mingw-get-setup.exe/download). During installation, uncheck the option to install a graphical user interface. **DO NOT change the default installation folder.** The scripts depend on the default location.
+3. Clone this repository. [This link will download it as a zip file, which you'll need to extract.](https://github.com/jackhumbert/qmk_firmware/archive/master.zip) Open the extracted folder in Windows Explorer.
+4. Right-click on the 1-setup-path-win batch script, select "Run as administrator", and accept the User Account Control prompt. Press the spacebar to dismiss the success message in the command prompt that pops up.
+5. Right-click on the 2-setup-environment-win batch script, select "Run as administrator", and accept the User Account Control prompt. This part may take a couple of minutes, and you'll need to approve a driver installation, but once it finishes, your environment is complete!
+
+
+### Mac
+
+If you're using homebrew, you can use the following commands:
+
+    brew tap osx-cross/avr
+    brew install avr-libc
+    brew install dfu-programmer
+
+Otherwise, these instructions will work:
+
+1. Install Xcode from the App Store.
+2. Install the Command Line Tools from `Xcode->Preferences->Downloads`.
+3. Install [DFU-Programmer][dfu-prog].
+
+### Linux
+1. Install AVR GCC with your favorite package manager.
+2. Install [DFU-Programmer][dfu-prog].
+
+Note that, since it will be directly accessing USB hardware, the
+`dfu-programmer` program needs to be run as root.
+
+## Verify Your Installation
+1. Clone the following repository: https://github.com/jackhumbert/qmk_firmware
+2. Open a Terminal and `cd` into `qmk_firmware/keyboard/planck`
+3. Run `make`. This should output a lot of information about the build process.
+
+## Using the built-in functions
+
+Here is a list of some of the functions available from the command line:
+
+* `make clean`: clean the environment - may be required in-between builds
+* `make`: compile the code
+* `make KEYMAP=<keymap>`: compile with the extended keymap file `extended_keymaps/extended_keymap_<keymap>.c`
+* `make dfu`: build and flash the layout to the PCB
+* `make dfu-force`: build and force-flash the layout to the PCB (may be require for first flash)
+
+Generally, the instructions to flash the PCB are as follows:
+
+1. Make changes to the appropriate keymap file
+2. Save the file
+3. `make clean`
+4. Press the reset button on the PCB/press the key with the `RESET` keycode
+5. `make <arguments> dfu` - use the necessary `KEYMAP=<keymap>` and/or `COMMON=true` arguments here.
+
+## Troubleshooting
+If you see something like this
+
+          0 [main] sh 13384 sync_with_child: child 9716(0x178) died before initialization with status code 0xC0000142
+        440 [main] sh 13384 sync_with_child: *** child state waiting for longjmp
+    /usr/bin/sh: fork: Resource temporarily unavailable
+
+after running 'make' on Windows than you are encountering a very popular issue with WinAVR on Windows 8.1 and 10.
+You can easily fix this problem by replacing msys-1.0.dll in WinAVR/utils/bin with [this one](http://www.madwizard.org/download/electronics/msys-1.0-vista64.zip).
+Restart your system and everything should work fine!
+
+
+If you see this
+
+    dfu-programmer atmega32u4 erase
+    process_begin: CreateProcess(NULL, dfu-programmer atmega32u4 erase, ...) failed.
+    make (e=2): The system cannot find the file specified.
+    make: *** [dfu] Error 2
+
+when trying to 'make dfu' on Windows you need to copy the dfu-programmer.exe to qmk_firmware/keyboard/planck.
+
+
+## Quantum MK Firmware
+
+### Keymap
+
+Unlike the other keymaps, prefixing the keycodes with `KC_` is required. A full list of the keycodes is available [here](https://github.com/jackhumbert/qmk_firmware/blob/master/tmk_core/doc/keycode.txt). For the keycodes available only in the extended keymap, see this [header file](https://github.com/jackhumbert/qmk_firmware/blob/master/quantum/keymap_common.h).
+
+You can use modifiers with keycodes like this:
+
+    LCTL(KC_C)
+    
+Which will generate Ctrl+c. These are daisy-chainable, meaning you can do things like:
+
+    LCTL(LALT(KC_C))
+    
+That will generate Ctrl+Alt+c. The entire list of these functions is here:
+
+* `LCTL()`: Left control
+* `LSFT()` / `S()`: Left shift
+* `LALT()`: Left alt/opt
+* `LGUI()`: Left win/cmd
+* `RCTL()`: Right control
+* `RSFT()`: Right shift
+* `RALT()`: Right alt/opt
+* `RGUI()`: Right win/cmd
+
+`S(KC_1)`-like entries are useful in writing keymaps for the Planck.
+
+### Other keycodes
+
+A number of other keycodes have been added that you may find useful:
+
+* `CM_<key>`: the Colemak equivalent of a key (in place of `KC_<key>`), when using Colemak in software (`CM_O` generates `KC_SCLN`)
+* `RESET`: jump to bootloader for flashing (same as press the reset button)
+* `BL_STEP`: step through the backlight brightnesses
+* `BL_<0-15>`: set backlight brightness to 0-15
+* `BL_DEC`: lower the backlight brightness
+* `BL_INC`: raise the backlight brightness
+* `BL_TOGG`: toggle the backlight on/off
+
+### Function layers
+
+The extended keymap extends the number of function layers from 32 to the near-infinite value of 256. Rather than using `FN<num>` notation (still available, but limited to `FN0`-`FN31`), you can use the `FUNC(<num>)` notation. `F(<num>)` is a shortcut for this.
+
+The function actions are unchanged, and you can see the full list of them [here](https://github.com/jackhumbert/tmk_keyboard/blob/master/common/action_code.h). They are explained in detail [here](https://github.com/jackhumbert/tmk_keyboard/blob/master/doc/keymap.md#2-action).
+
+### Macros
+
+Macros have been setup in the `keymaps/keymap_default.c` file so that you can use `M(<num>)` to access a macro in the `action_get_macro` section on your keymap. The switch/case structure you see here is required, and is setup for `M(0)` - you'll need to copy and paste the code to look like this (e.g. to support `M(3)`):
+
+    switch(id) {
+      case 0:
+        return MACRODOWN(TYPE(KC_A), END);
+        break;
+      case 1:
+        return MACRODOWN(TYPE(KC_B), END);
+        break;
+      case 2:
+        return MACRODOWN(TYPE(KC_C), END);
+        break;
+      case 3:
+        return MACRODOWN(TYPE(KC_D), END);
+        break;
+    } 
+    return MACRO_NONE;
+
+`MACRODOWN()` is a shortcut for `(record->event.pressed ? MACRO(__VA_ARGS__) : MACRO_NONE)` which tells the macro to execute when the key is pressed. Without this, the macro will be executed on both the down and up stroke.

+Build Firmware and Program Controller
+-------------------------------------
+See [doc/build.md](tmk_core/doc/build.md), or the README in the particular keyboard/* folder.
+
+
+
+Change your keymap
+------------------
+See [doc/keymap.md](tmk_core/doc/keymap.md).
+
+
+
+Magic Commands
+--------------
+To see help press `Magic` + `H`.
+
+`Magic` key combination is `LShift` + `RShift` in many project, but `Power` key on ADB converter. 
+`Magic` keybind can be vary on each project, check `config.h` in project directory.
+
+Following commands can be also executed with `Magic` + key. In console mode `Magic` keybind is not needed.
+

+
+Boot Magic Configuration - Virtual DIP Switch
+---------------------------------------------
+Boot Magic are executed during boot up time. Press Magic key below then plug in keyboard cable.
+Note that you must use keys of **Layer 0** as Magic keys. These settings are stored in EEPROM so that retain your configure over power cycles.
+
+To avoid configuring accidentally additive salt key `KC_SPACE` also needs to be pressed along with the following configuration keys. The salt key is configurable in `config.h`. See [tmk_core/common/bootmagic.h](tmk_core/common/bootmagic.h).
+
+#### General
+- Skip reading EEPROM to start with default configuration(`ESC`)
+- Clear configuration stored in EEPROM to reset configuration(`Backspace`)
+
+#### Bootloader
+- Kick up Bootloader(`B`)
+
+#### Debug
+- Debug enable(`D`)
+- Debug matrix enable(`D`+`X`)
+- Debug keyboard enable(`D`+`K`)
+- Debug mouse enable(`D`+`M`)
+
+#### Keymap
+- Swap Control and CapsLock(`Left Control`)
+- Change CapsLock to Control(`Caps Lock`)
+- Swap LeftAlt and Gui(`Left Alt`)
+- Swap RightAlt and Gui(`Right Alt`)
+- Disable Gui(`Left Gui`)
+- Swap Grave and Escape(`Grave`)
+- Swap BackSlash and BackSpace(`Back Slash`)
+- Enable NKRO on boot(`N`)
+
+#### Default Layer
+- Set Default Layer to 0(`0`)
+- Set Default Layer to 1(`1`)
+- Set Default Layer to 2(`2`)
+- Set Default Layer to 3(`3`)
+- Set Default Layer to 4(`4`)
+- Set Default Layer to 5(`5`)
+- Set Default Layer to 6(`6`)
+- Set Default Layer to 7(`7`)
+
+
+
+Mechanical Locking support
+--------------------------
+This feature makes it possible for you to use mechanical locking switch for `CapsLock`, `NumLock` 
+or `ScrollLock`. To enable this feature define these macros in `config.h` and use `KC_LCAP`, `KC_LN
+UM` or `KC_LSCR` in keymap for locking key instead of normal `KC_CAPS`, `KC_NLCK` or `KC_SLCK`. Res
+ync option tries to keep switch state consistent with keyboard LED state.
+ 
+    #define LOCKING_SUPPORT_ENABLE
+    #define LOCKING_RESYNC_ENABLE
+
+
+
+Start Your Own Project
+-----------------------
+**TBD**
+
+
+
+Debugging
+--------
+Use PJRC's `hid_listen` to see debug messages. You can use the tool for debug even if firmware use LUFA stack.
+
+You can use xprintf() to display debug info on `hid_listen`, see `tmk_core/common/xprintf.h`.

+Terminology
+---------
+NKRO
+ghost
+matrix
+mechanical with diodes
+membrane
+
+
+OS Support Status
+-----------------
+USB NKRO is possible *without* a custom driver.
+At least following OS's supports.
+    Windows7 64bit
+    WindowsXP
+    Windows2000 SP4
+    Ubuntu10.4(Linux 2.6)
+    MacOSX(To be tested)
+
+
+Custom Driver for USB NKRO
+--------------------------
+NOT NEEDED
+at least when using following report formats on Windows, Linux or MacOSX.
+
+
+USB NKRO methods
+----------------
+1. Virtual keyboards
+    Keyboard can increase its KRO by using virtual keyboards with Standard or Extended report.
+    If the keyboard has 2 virtual keyboard with Standard report(6KRO), it gets 12KRO.
+    Using this method means the keyboard is a composite device.
+
+2. Extended report
+    It needs large report size for this method to achieve NKRO.
+    If a keyboard has 101keys, it needs 103byte report. It seems to be inefficient.
+
+3. Bitmap report
+    If the keyboard has less than 128keys, 16byte report will be enough for NKRO.
+    The 16byte report seems to be reasonable cost to get NKRO.
+
+
+Report Format
+-------------
+Other report formats than followings are possible, though these format are typical one.
+
+1. Standard             8bytes
+    modifiers(bitmap)       1byte
+    reserved                1byte(not used)
+    keys(array)             1byte*6
+Standard report can send 6keys plus 8modifiers simultaneously.
+Standard report is used by most keyboards in the marketplace.
+Standard report is identical to boot protocol report.
+Standard report is hard to suffer from compatibility problems.
+
+2. Extended standard    16,32,64bytes
+    modifiers(bitmap)       1byte
+    reserved                1byte(not used)
+    keys(array)             1byte*(14,32,62)
+Extended report can send N-keys by using N+2bytes.
+Extended report is expected to be compatible with boot protocol.
+
+3. Bitmap               16,32,64bytes
+    keys(bitmap)            (16,32)bytes
+Bitmap report can send at most 128keys by 16bytes and 256keys by 32bytes.
+Bitmap report can achieve USB NKRO efficiently in terms of report size.
+Bitmap report needs a deliberation for boot protocol implementation.
+Bitmap report descriptor sample:
+        0x05, 0x01,                     // Usage Page (Generic Desktop),
+        0x09, 0x06,                     // Usage (Keyboard),
+        0xA1, 0x01,                     // Collection (Application),
+        // bitmap of modifiers
+        0x75, 0x01,                     //   Report Size (1),

+        0x15, 0x00,                     //   Logical Minimum (0),
+        0x25, 0x01,                     //   Logical Maximum (1),
+        0x81, 0x02,                     //   Input (Data, Variable, Absolute), ;Modifier byte
+        // LED output report
+        0x95, 0x05,                     //   Report Count (5),
+        0x75, 0x01,                     //   Report Size (1),

+Considerations
+--------------
+Compatibility
+    boot protocol
+    minor/old system
+        Some BIOS doesn't send SET_PROTOCOL request, a keyboard can't switch to boot protocol mode.
+        This may cause a problem on a keyboard which uses other report than Standard.
+Reactivity
+    USB polling time
+    OS/Driver processing time
+
+
+Windows Problem
+---------------
+1. Windows accepts only 6keys  in case of Standard report.
+        It should be able to send 6keys plus 8modifiers.
+2. Windows accepts only 10keys in case of 16bytes Extended report.
+        It should be able to send 14keys plus 8modifiers.
+3. Windows accepts only 18keys in case of 32bytes Extended report.
+        It should be able to send 30keys plus 8modifiers.
+If keys are pressed in excess of the number, wrong keys are registered on Windows.
+
+This problem will be reportedly fixed soon.(2010/12/05)

+# Quick Start Directions
+
+This project includes a Vagrantfile that will allow you to build a new firmware for your keyboard very easily without major changes to your primary operating system. This also ensures that when you clone the project and perform a build, you have the exact same environment as anyone else using the Vagrantfile to build. This makes it much easier for people to help you troubleshoot any issues you encounter.
+
+## Requirements
+
+Using the `/util/Vagrantfile` in this repository requires you have [Vagrant](http://www.vagrantup.com/) as well as [VirtualBox](https://www.virtualbox.org/) (or [VMware Workstation](https://www.vmware.com/products/workstation) and [Vagrant VMware plugin](http://www.vagrantup.com/vmware) but the (paid) VMware plugin requires a licensed copy of VMware Workstation/Fusion).
+
+*COMPATIBILITY NOTICE* Certain versions of Virtualbox 5 appear to have an incompatibility with the Virtualbox extensions installed in the boxes in this Vagrantfile. If you encounter any issues with the /vagrant mount not succeeding, please upgrade your version of Virtualbox to at least 5.0.12.
+
+Other than having Vagrant and Virtualbox installed and possibly a restart of your computer afterwards, you can simple run a 'vagrant up' anywhere inside the folder where you checked out this project and it will start a Linux virtual machine that contains all the tools required to build this project. There is a post Vagrant startup hint that will get you off on the right foot, otherwise you can also reference the build documentation below.
+
+Build Firmware and Program Controller
+-------------------------------------
+See [/doc/BUIDE_GUIDE.md](/doc/BUILD_GUIDE.md), or the README in the particular keyboard/* folder.
+
+Change your keymap
+------------------
+See [/doc/keymap.md](/doc/keymap.md).
+
+## Flashing the firmware
+
+The "easy" way to flash the firmware is using a tool from your host OS like the Teensy programming app. [ErgoDox EZ](/keyboard/ergodox_ez/readme.md) gives a great example.
+
+If you want to program via the command line you can uncomment the ['modifyvm'] lines in the Vagrantfile to enable the USB passthrough into Linux and then program using the command line tools like dfu-util/dfu-programmer or you can install the Teensy CLI version.

+Build Firmware and Program Controller
+=====================================
+
+## This guide may be out-dated - use doc/BUILD_GUIDE.md instead
+
+Download and Install
+--------------------
+### 1. Install Tools
+
+1. **Toolchain** On Windows install [MHV AVR Tools][mhv] for AVR GCC compiler and [Cygwin][cygwin](or [MinGW][mingw]) for shell terminal. On Mac you can use [CrossPack][crosspack]. On Linux you can install AVR GCC (and avr-libc) with your favorite package manager or run the avr_setup.sh script in the root of this repository.
+
+2. **Programmer** On Windows install [Atmel FLIP][flip]. On Mac and Linux install [dfu-programmer][dfu-prog].
+
+3. **Driver** On Windows you start DFU bootloader on the chip first time you will see 'Found New Hardware Wizard' to install driver. If you install device driver properly you can find chip name like 'ATmega32U4' under 'LibUSB-Win32 Devices' tree on 'Device Manager'. If not you shall need to update its driver on 'Device Manager'. You will find the driver in `FLIP` install directory like: C:\Program Files (x86)\Atmel\Flip 3.4.5\usb\. In case of `dfu-programmer` use its driver.
+
+If you use PJRC Teensy you don't need step 2 and 3 above, just get [Teensy loader][teensy-loader].
+
+
+### 2. Download source
+You can find firmware source at github:
+
+- <https://github.com/tmk/tmk_keyboard>
+
+If you are familiar with `Git` tools you are recommended to use it but you can also download zip archive from:
+
+- <https://github.com/tmk/tmk_keyboard/archive/master.zip>
+
+
+Build firmware
+--------------
+### 1. Open terminal
+Open terminal window to get access to commands. Use Cygwin(or MingGW) `shell terminal` in Windows or `Terminal.app` on Mac OSX. In Windows press `Windows` key and `R` then enter `cmd` in 'Run command' dialog showing up.
+
+### 2. Change directory
+Move to project directory in the firmware source.
+
+    cd tmk_keyboard/{'keyboard' or 'converter'}/<project>
+
+### 3. Make
+Build firmware using GNU `make` command. You'll see `<project>_<variant>.hex` file in that directory unless something unexpected occurs in build process.
+
+
+    make -f Makefile.<variant> clean
+    make -f Makefile.<variant>
+
+
+
+
+Program Controller
+------------------
+Now you have **hex** file to program on current directory. This **hex** is only needed to program your controller, other files are used for development and you may leave and forget them.
+
+### 1. Start bootloader
+How to program controller depends on controller chip and its board design. To program AVR USB chips you'll need to start it up in bootloader mode. Most of boards with the chip have a push button to let bootloader come up. Consult with your controller board manual.
+
+### 2. Program with DFU bootloader
+Stock AVR USB chip including ATmega32U4 has DFU bootloader by factory default. `FLIP` is a DFU programmer on Windows offered by Atmel. Open source command line tool `dfu-programmer` also supports AVR chips, it runs on Linux, Mac OSX and even Windows.
+
+To program AVR chip with DFU bootloader use `FLIP` or `dfu-programmer`.
+If you have a proper program command in `Makefile` just type this.
+
+`FLIP` has two version of tool, GUI app and command line program. If you want GUI see tutorial below.
+To use command line tool run this command. Note that you need to set PATH variable properly.
+
+    $ make -f Makefile.<variant> flip
+
+Or to program with `dfu-programmer` run:
+
+    $ make -f Makefile.<variant> dfu
+
+#### FLIP GUI tutorial
+1. On menu bar click Device -> Select, then. `ATmega32u4`.
+2. On menu bar click Settings -> Communication -> USB, then click 'Open' button on 'USB Port Connection' dialog.
+At this point you'll see grey-outed widgets on the app get colored and ready.
+
+3. On menu bar click File -> Load HEX File, then select your firmware hex file on File Selector dialog.
+4. On 'Operations Flow' panel click 'Run' button to load the firmware binary to the chip. Note that you should keep 'Erase', 'Blank Check', 'Program' and 'Verify' check boxes selected.
+5. Re-plug USB cord or click 'Start Application' button to restart your controller.
+Done.
+
+See also these instructions if you need.
+
+- <http://code.google.com/p/micropendous/wiki/LoadingFirmwareWithFLIP>
+- <http://www.atmel.com/Images/doc7769.pdf>
+
+
+### 3. Program with Teensy Loader
+If you have PJRC Teensy see instruction of `Teensy Loader`.
+
+- <http://www.pjrc.com/teensy/loader.html>
+
+Or use this command if you have command line version of Teensy Loader installed.
+
+    $ make -f Makefile.<variant> teensy
+
+
+### 4. Program with Other programmer
+You may want to use other programmer like `avrdude` with AVRISPmkII, Arduino or USBasp. In that case you can still use make target `program` for build with configuring `PROGRAM_CMD` in Makefile.
+
+    $ make -f Makefile.<variant> program

+Keymap framework - how to define your keymap
+============================================
+***NOTE: This is not final version, may be inconsistent with source code and changed occasionally for a while.***
+
+## 0. Keymap and layers
+**Keymap** is comprised of multiple layers of key layout, you can define **32 layers** at most.
+**Layer** is an array of **keycodes** to define **actions** for each physical keys.
+respective layers can be validated simultaneously. Layers are indexed with 0 to 31 and higher layer has precedence.
+
+    Keymap: 32 Layers                   Layer: Keycode matrix
+    -----------------                   ---------------------
+    stack of layers                     array_of_keycode[row][column]
+           ____________ precedence               _______________________

+      31 /___________// |                      /-----/-----/-----/-----
+      30 /___________// |                     / TAB /  Q  /  W  /  E   ....
+      29 /___________/  |                    /-----/-----/-----/-----
+       :   _:_:_:_:_:__ |               :   /LCtrl/  A  /  S  /  D   ....
+       :  / : : : : : / |               :  /  :     :     :     :

+       0 /___________/  V low           0 `--------------------------
+
+
+
+### 0.1 Keymap status
+Keymap has its state in two parameters:
+**`default_layer`** indicates a base keymap layer(0-31) which is always valid and to be referred, **`keymap_stat`** is 16bit variable which has current on/off status of layers on its each bit.
+
+Keymap layer '0' is usually `default_layer` and which is the only valid layer and other layers is initially off after boot up firmware, though, you can configured them in `config.h`.
+To change `default_layer` will be useful when you switch key layout completely, say you want Colmak instead of Qwerty.
+
+    Initial state of Keymap          Change base layout              
+    -----------------------          ------------------

+      29                               29
+       :                                :
+       :                                :   ____________
+       2   ____________                 2  /           /
+       1  /           /              ,->1 /___________/
+    ,->0 /___________/               |  0
+    |                                |
+    `--- default_layer = 0           `--- default_layer = 1
+         layer_state   = 0x00000001       layer_state   = 0x00000002
+
+On the other hand, you shall change `layer_state` to overlay base layer with some layers for feature such as navigation keys, function key(F1-F12), media keys or special actions.
+

+      30 /___________// -----> 30 |   1
+      29 /___________/  -----> 29 |   1

+    |  0                        0 |   0
+    |                                 +
+    `--- default_layer = 1            |
+         layer_state   = 0x60000002 <-'
+
+
+
+### 0.2 Layer Precedence and Transparency
+Note that ***higher layer has higher priority on stack of layers***, namely firmware falls down from top layer to bottom to look up keycode. Once it spots keycode other than **`KC_TRNS`**(transparent) on a layer it stops searching and lower layers aren't referred.
+
+You can place `KC_TRNS` on overlay layer changes just part of layout to fall back on lower or base layer.
+Key with `KC_TRANS` doesn't has its own keycode and refers to lower valid layers for keycode, instead.
+See example below.
+
+
+### 0.3 Keymap Example
+Keymap is **`keymaps[]`** C array in fact and you can define layers in it with **`KEYMAP()`** C macro and keycodes. To use complex actions you need to define `Fn` keycode in **`fn_actions[]`** array.
+
+This is a keymap example for [HHKB](http://en.wikipedia.org/wiki/Happy_Hacking_Keyboard) keyboard.
+This example has three layers, 'Qwerty' as base layer, 'Cursor' and  'Mousekey'.
+In this example,
+
+ `Fn0` is a **momentary layer switching** key, you can use keys on Cursor layer while holding the key.
+
+ `Fn1` is a momentary layer switching key with tapping feature, you can get semicolon **';'** with taping the key and switch layers while holding the key. The word **'tap'** or **'tapping'** mean to press and release a key quickly.
+
+ `Fn2` is a **toggle layer switch** key, you can stay switched layer after releasing the key unlike momentary switching.
+
+You can find other keymap definitions in file `keymap.c` located on project directories.

+## 1. Keycode
+See [`common/keycode.h`](../common/keycode.h) or keycode table below for the detail. Keycode is internal **8bit code** to indicate action performed on key in keymap. Keycode has `KC_` prefixed symbol respectively. Most of keycodes like `KC_A` have simple action registers key to host on press and unregister on release, while some of other keycodes has some special actions like `Fn` keys, Media control keys, System control keys and Mousekeys.
+
+ ***In `KEYMAP()` macro you should omit prefix part `KC_` of keycode to keep keymap compact.*** For example, just use `A` instead you place `KC_A` in `KEYMAP()`. Some keycodes has 4-letter **short name** in addition to descriptive name, you'll prefer short one in `KEYMAP()`.
+
+### 1.0 Other key
+- `KC_NO` for no action
+- `KC_TRNS` for layer transparency (See above)
+
+### 1.1 Normal key
+- `KC_A` to `KC_Z`, `KC_1` to `KC_0` for alpha numeric key
+- `KC_MINS`, `KC_EQL`, `KC_GRV`, `KC_RBRC`, `KC_LBRC`, `KC_COMM`, `KC_DOT`, `KC_BSLS`, `KC_SLSH`, `KC_SCLN`, `KC_QUOT`
+- `KC_ESC`, `KC_TAB`, `KC_SPC`, `KC_BSPC`, `KC_ENT`, `KC_DEL`, `KC_INS`
+- `KC_UP`, `KC_DOWN`, `KC_RGHT`, `KC_LEFT`, `KC_PGUP`, `KC_PGDN`, `KC_HOME`, `KC_END`
+- `KC_CAPS`, `KC_NLCK`, `KC_SLCK`, `KC_PSCR`, `KC_PAUS`, `KC_APP`, `KC_F1` to `KC_F24`
+- `KC_P1` to `KC_P0`, `KC_PDOT`, `KC_PCMM`, `KC_PSLS`, `KC_PAST`, `KC_PMNS`, `KC_PPLS`, `KC_PEQL`, `KC_PENT` for keypad.
+
+### 1.2 Modifier
+There are 8 modifiers which has discrimination between left and right. 
+
+- `KC_LCTL` and `KC_RCTL` for Control
+- `KC_LSFT` and `KC_RSFT` for Shift
+- `KC_LALT` and `KC_RALT` for Alt
+- `KC_LGUI` and `KC_RGUI` for Windows key or Command key in Mac
+
+### 1.3 Mousekey
+- `KC_MS_U`, `KC_MS_D`, `KC_MS_L`, `KC_MS_R` for mouse cursor
+- `KC_WH_U`, `KC_WH_D`, `KC_WH_L`, `KC_WH_R` for mouse wheel
+- `KC_BTN1`, `KC_BTN2`, `KC_BTN3`, `KC_BTN4`, `KC_BTN5` for mouse buttons
+
+### 1.4 System & Media key
+- `KC_PWR`, `KC_SLEP`, `KC_WAKE` for Power, Sleep, Wake
+- `KC_MUTE`, `KC_VOLU`, `KC_VOLD` for audio volume control
+- `KC_MNXT`, `KC_MPRV`, `KC_MSTP`, `KC_MPLY`, `KC_MSEL` for media control
+- `KC_MAIL`, `KC_CALC`, `KC_MYCM` for application launch
+- `KC_WSCH`, `KC_WHOM`, `KC_WBAK`, `KC_WFWD`, `KC_WSTP`, `KC_WREF`, `KC_WFAV` for web browser operation
+
+### 1.5 Fn key
+`KC_FNnn` are keycodes for `Fn` key which not given any actions at the beginning unlike most of keycodes has its own inborn action. To use these keycodes in `KEYMAP()` you need to assign action you want at first. Action of `Fn` key is defined in `fn_actions[]` and its index of the array is identical with number part of `KC_FNnn`. Thus `KC_FN0` keycode indicates the action defined in first element of the array. ***32 `Fn` keys can be defined at most.***
+
+### 1.6 Keycode Table
+ See keycode table in [`doc/keycode.txt`](./keycode.txt) for description of keycodes.
+
+ In regard to implementation side most of keycodes are identical with [HID usage][HID_usage](pdf) sent to host for real and some virtual keycodes are defined to support special actions.
+[HID_usage]: http://www.usb.org/developers/hidpage/Hut1_12v2.pdf
+
+
+
+## 2. Action
+See [`common/action_code.h`](../common/action_code.h). Action is a **16bit code** and defines function to perform on events of a key like press, release, holding and tapping.
+
+Most of keys just register 8bit scancode to host, but to support other complex features needs 16bit extended action codes internally. However, using 16bit action codes in keymap results in double size in memory compared to using just keycodes. To avoid this waste 8bit keycodes are used in `KEYMAP()` instead of action codes.
+
+***You can just use keycodes of `Normal key`, `Modifier`, `Mousekey` and `System & Media key` in keymap*** to indicate corresponding actions instead of using action codes. While ***to use other special actions you should use keycode of `Fn` key defined in `fn_actions[]`.***
+
+
+### 2.1 Key Action
+This is a simple action that registers scancodes(HID usage in fact) to host on press event of key and unregister on release.
+
+#### Parameters
++ **mods**: { ` MOD_LCTL`, ` MOD_LSFT`, ` MOD_LALT`, ` MOD_LGUI`,
+              ` MOD_RCTL`, ` MOD_RSFT`, ` MOD_RALT`, ` MOD_RGUI` }
++ **key**: keycode
+
+
+#### 2.1.1 Normal key and Modifier
+***This action usually won't be used expressly in keymap*** because you can just use keycodes in `KEYMAP()` instead.
+
+You can define these actions on *'A'* key and *'left shift'* modifier with:
+
+    ACTION_KEY(KC_A)
+    ACTION_KEY(KC_LSFT)
+
+#### 2.1.2 Modified key
+This action is comprised of strokes of modifiers and a key. `Macro` action is needed if you want more complex key strokes.
+
+Say you want to assign a key to `Shift + 1` to get character *'!'* or `Alt + Tab` to switch application windows.
+
+    ACTION_MODS_KEY(MOD_LSFT, KC_1)
+    ACTION_MODS_KEY(MOD_LALT, KC_TAB)
+
+Or `Alt,Shift + Tab` can be defined. `ACTION_MODS_KEY(mods, key)` requires **4-bit modifier state** and a **keycode** as arguments. See `keycode.h` for `MOD_BIT()` macro.
+
+    ACTION_MODS_KEY(MOD_LALT | MOD_LSFT, KC_TAB)
+
+#### 2.1.3 Multiple Modifiers
+Registers multiple modifiers with pressing a key. To specify multiple modifiers use `|`.
+
+    ACTION_MODS(MOD_ALT | MOD_LSFT)
+
+#### 2.1.3 Modifier with Tap key([Dual role][dual_role])
+Works as a modifier key while holding, but registers a key on tap(press and release quickly).
+
+
+    ACTION_MODS_TAP_KEY(MOD_RCTL, KC_ENT)
+
+
+
+### 2.2 Layer Action
+These actions operate layers of keymap.
+
+#### Parameters
+You can specify a **target layer** of action and **when the action is executed**. Some actions take a **bit value** for bitwise operation.
+
+
++ **layer**: `0`-`31`
++ **on**: { `ON_PRESS` | `ON_RELEASE` | `ON_BOTH` }
++ **bits**: 4-bit value and 1-bit mask bit
+
+
+#### 2.2.1 Default Layer
+Default Layer is a layer which always is valid and referred to when actions is not defined on other overlay layers.
+
+This sets Default Layer to given parameter `layer` and activate it.
+
+    ACTION_DEFAULT_LAYER_SET(layer)
+
+
+#### 2.2.2 Momentary 
+Turns on `layer` momentarily while holding, in other words it activates when key is pressed and deactivate when released.
+
+    ACTION_LAYER_MOMENTARY(layer)
+
+
+#### 2.2.3 Toggle Switch
+Turns on `layer` with first type(press and release) and turns off with next.
+
+    ACTION_LAYER_TOGGLE(layer)
+
+
+#### 2.2.4 Momentary Switch with tap key
+Turns on `layer` momentary while holding, but registers key on tap(press and release quickly).
+
+    ACTION_LAYER_TAP_KEY(layer, key)
+
+
+#### 2.2.5 Momentary Switch with tap toggle
+Turns on `layer` momentary while holding and toggles it with serial taps.
+
+    ACTION_LAYER_TAP_TOGGLE(layer)
+
+
+#### 2.2.6 Invert state of layer
+Inverts current state of `layer`. If the layer is on it becomes off with this action.
+
+    ACTION_LAYER_INVERT(layer, on)
+
+
+#### 2.2.7 Turn On layer
+Turns on layer state.
+
+    ACTION_LAYER_ON(layer, on)
+
+Turns on layer state on press and turns off on release.
+
+    ACTION_LAYER_ON_OFF(layer)
+
+
+#### 2.2.8 Turn Off layer
+Turns off layer state.
+
+    ACTION_LAYER_OFF(layer, on)
+
+Turns off layer state on press and activates on release.
+
+    ACTION_LAYER_OFF_ON(layer)
+
+
+#### 2.2.9 Set layer
+Turn on layer only.
+`layer_state = (1<<layer) [layer: 0-31]`
+
+    ACTION_LAYER_SET(layer, on)
+
+Turns on layer only and clear all layer on release..
+
+    ACTION_LAYER_SET_CLEAR(layer)
+
+
+#### 2.2.10 Bitwise operation
+
+**part** indicates which part of 32bit layer state(0-7). **bits** is 5-bit value. **on** indicates when the action is executed.
+
+    ACTION_LAYER_BIT_AND(part, bits, on)
+    ACTION_LAYER_BIT_OR(part, bits, on)
+    ACTION_LAYER_BIT_XOR(part, bits, on)
+    ACTION_LAYER_BIT_SET(part, bits, on)
+
+These actions works with parameters as following code.
+
+    uint8_t shift = part*4;
+    uint32_t mask = (bits&0x10) ? ~(0xf<<shift) : 0;
+    uint32_t layer_state = layer_state <bitop> ((bits<<shift)|mask);
+
+
+Default Layer also has bitwise operations, they are executed when key is released.
+
+    ACTION_DEFAULT_LAYER_BIT_AND(part, bits)
+    ACTION_DEFAULT_LAYER_BIT_OR(part, bits)
+    ACTION_DEFAULT_LAYER_BIT_XOR(part, bits)
+    ACTION_DEFAULT_LAYER_BIT_SET(part, bits)
+
+
+
+### 2.3 Macro action
+***TBD***
+
+`Macro` action indicates complex key strokes.
+ 
+    MACRO( D(LSHIFT), D(D), END )
+    MACRO( U(D), U(LSHIFT), END )
+    MACRO( I(255), T(H), T(E), T(L), T(L), W(255), T(O), END )
+
+#### 2.3.1 Macro Commands
+- **I()**   change interval of stroke.
+- **D()**   press key
+- **U()**   release key
+- **T()**   type key(press and release)
+- **W()**   wait
+- **END**   end mark
+
+#### 2.3.2 Examples
+
+***TODO: sample implementation***
+See `keyboard/hhkb/keymap.c` for sample.
+
+
+
+### 2.4 Function action
+***TBD***
+
+There are two type of action, normal `Function` and tappable `Function`.
+These actions call user defined function with `id`, `opt`, and key event information as arguments.
+
+#### 2.4.1 Function
+To define normal `Function` action in keymap use this.
+
+    ACTION_FUNCTION(id, opt)
+
+#### 2.4.2 Function with tap
+To define tappable `Function` action in keymap use this.
+
+    ACTION_FUNCTION_TAP(id, opt)
+
+#### 2.4.3 Implement user function
+`Function` actions can be defined freely with C by user in callback function:
+
+    void keymap_call_function(keyrecord_t *event, uint8_t id, uint8_t opt)
+
+This C function is called every time key is operated, argument `id` selects action to be performed and `opt` can be used for option. Function `id` can be 0-255 and `opt` can be 0-15.
+
+ `keyrecord_t` is comprised of key event and tap count. `keyevent_t` indicates which and when key is pressed or released. From `tap_count` you can know tap state, 0 means no tap. These information will be used in user function to decide how action of key is performed.
+
+    typedef struct {
+        keyevent_t  event;
+        uint8_t     tap_count;
+    } keyrecord_t;
+
+    typedef struct {
+        key_t    key;
+        bool     pressed;
+        uint16_t time;
+    } keyevent_t;
+
+    typedef struct {
+        uint8_t col;
+        uint8_t row;
+    } key_t;
+
+***TODO: sample implementation***
+See `keyboard/hhkb/keymap.c` for sample.
+
+
+
+### 2.5 Backlight Action
+These actions control the backlight.
+
+#### 2.5.1 Change backlight level
+Increase backlight level.
+
+    ACTION_BACKLIGHT_INCREASE()
+
+Decrease backlight level.
+
+    ACTION_BACKLIGHT_DECREASE()
+
+Step through backlight levels.
+
+    ACTION_BACKLIGHT_STEP()
+
+Turn a specific backlight level on or off.
+
+    ACTION_BACKLIGHT_LEVEL(1)
+
+#### 2.5.2 Turn on / off backlight
+Turn the backlight on and off without changing level.
+
+    ACTION_BACKLIGHT_TOGGLE()
+
+
+
+## 3. Layer switching Example
+There are some ways to switch layer with 'Layer' actions.
+
+### 3.1 Momentary switching
+Momentary switching changes layer only while holding Fn key.
+
+This action makes 'Layer 1' active(valid) on key press event and inactive on release event. Namely you can overlay a layer on lower layers or default layer temporarily with this action.
+
+    ACTION_LAYER_MOMENTARY(1)
+
+
+Note that after switching on press the actions on destination layer(Layer 1) are performed.
+***Thus you shall need to place an action to go back on destination layer***, or you will be stuck in destination layer without way to get back. Usually you need to place same action or 'KC_TRNS` on destination layer to get back.
+
+
+### 3.2 Toggle switching
+Toggle switching performed after releasing a key. With this action you can keep staying on the destination layer until you type the key again to return.
+
+This performs toggle switching action of 'Layer 2'.
+
+    ACTION_LAYER_TOGGLE(2)
+
+
+
+### 3.3 Momentary switching with Tap key
+These actions switch a layer only while holding a key but register the key on tap. **Tap** means to press and release a key quickly.
+
+    ACTION_LAYER_TAP_KEY(2, KC_SCLN)
+
+With this you can place a layer switching action on normal key like ';' without losing its original key register function. This action allows you to have layer switching action without necessity of a dedicated key. It means you can have it even on home row of keyboard.
+
+
+
+### 3.4 Momentary switching with Tap Toggle
+This switches layer only while holding a key but toggle layer with several taps. **Tap** means to press and release key quickly.
+
+    ACTION_LAYER_TAP_TOGGLE(1)
+
+Number of taps can be configured with `TAPPING_TOGGLE` in `config.h`, `5` by default.
+
+
+
+### 3.5 Momentary switching with Modifiers
+This registers modifier key(s) simultaneously with layer switching.
+
+    ACTION_LAYER_MODS(2, MOD_LSFT | MOD_LALT)
+
+
+
+## 4. Tapping
+Tapping is to press and release a key quickly. Tapping speed is determined with setting of `TAPPING_TERM`, which can be defined in `config.h`, 200ms by default.
+
+### 4.1 Tap Key
+This is a feature to assign normal key action and modifier including layer switching to just same one physical key. This is a kind of [Dual role key][dual_role]. It works as modifier when holding the key but registers normal key when tapping.
+
+Modifier with tap key:
+
+    ACTION_MODS_TAP_KEY(MOD_RSFT, KC_GRV)
+
+Layer switching with tap key:
+
+    ACTION_LAYER_TAP_KEY(2, KC_SCLN)
+
+[dual_role]: http://en.wikipedia.org/wiki/Modifier_key#Dual-role_keys
+
+
+### 4.2 Tap Toggle
+This is a feature to assign both toggle layer and momentary switch layer action to just same one physical key. It works as momentary layer switch when holding a key but toggle switch with several taps.
+
+    ACTION_LAYER_TAP_TOGGLE(1)
+
+
+### 4.3 Oneshot Modifier
+This runs onetime effects which modify only on just one following key. It works as normal modifier key when holding down while oneshot modifier when tapping. The behavior of oneshot modifiers is similar to the [sticky keys](https://en.wikipedia.org/wiki/StickyKeys) functionality found in most operating systems.
+
+    ACTION_MODS_ONESHOT(MOD_LSFT)
+
+Oneshot layer key:
+
+    ACTION_LAYER_ONESHOT(MY_LAYER)
+
+Say you want to type 'The', you have to push and hold Shift key before type 't' then release it before type 'h' and 'e', otherwise you'll get 'THe' or 'the' unintentionally. With Oneshot Modifier you can tap Shift then type 't', 'h' and 'e' normally, you don't need to holding Shift key properly here. This mean you can release Shift before 't' is pressed down.
+
+Oneshot effect is cancel unless following key is pressed down within `ONESHOT_TIMEOUT` of `config.h`. No timeout when it is `0` or not defined.
+
+Most implementations of sticky keys allow you to lock a modifier by double tapping the modifier. The layer then remains locked untill the modifier is tapped again. To enable this behaviour for oneshot modifiers set `ONESHOT_TAP_TOGGLE` to the number taps required. The feature is disabled if `ONESHOT_TAP_TOGGLE<2` or not defined.
+
+
+### 4.4 Tap Toggle Mods
+Similar to layer tap toggle, this works as a momentary modifier when holding, but toggles on with several taps. A single tap will 'unstick' the modifier again.
+
+    ACTION_MODS_TAP_TOGGLE(MOD_LSFT)
+
+
+
+
+## 5. Legacy Keymap
+This was used in prior version and still works due to legacy support code in `common/keymap.c`. Legacy keymap doesn't support many of features that new keymap offers. ***It is not recommended to use Legacy Keymap for new project.***
+
+To enable Legacy Keymap support define this macro in `config.h`.
+
+    #define USE_LEGACY_KEYMAP
+
+Legacy Keymap uses two arrays `fn_layer[]` and `fn_keycode[]` to define Fn key. The index of arrays corresponds with postfix number of `Fn` key. Array `fn_layer[]` indicates destination layer to switch and `fn_keycode[]` has keycodes to send when tapping `Fn` key.
+
+In following setting example, `Fn0`, `Fn1` and `Fn2` switch layer to 1, 2 and 2 respectively. `Fn2` registers `Space` key when tapping while `Fn0` and `Fn1` doesn't send any key.
+
+    static const uint8_t PROGMEM fn_layer[] = {
+        1,              // Fn0
+        2,              // Fn1
+        2,              // Fn2
+    };
+
+    static const uint8_t PROGMEM fn_keycode[] = {
+        KC_NO,          // Fn0
+        KC_NO,          // Fn1
+        KC_SPC,         // Fn2
+    };
+
+
+## 6. Terminology
+***TBD***
+### keymap
+is comprised of multiple layers.
+### layer
+is matrix of keycodes.
+### key
+is physical button on keyboard or logical switch on software.
+### keycode
+is codes used on firmware.
+### action
+is a function assigned on a key.
+### layer transparency
+Using transparent keycode one layer can refer key definition on other lower layer.
+### layer precedence
+Top layer has higher precedence than lower layers.
+### tapping
+is to press and release a key quickly.
