+# ARM Debugging usign Eclipse
+
+This page describes how to setup debugging for ARM MCUs using an SWD adapter and open-source/free tools. In this guide we will install GNU MCU Eclipse IDE for C/C++ Developers and OpenOCD together with all the necessary dependencies.
+
+This guide is catered towards advance users and assumes you can compile an ARM compatible keyboard on your machine using the MAKE flow.
+
+## Installing the software
+
+The main objective here is to get the MCU Eclipse IDE correcly installed on our machine. The necesarry instructions are derived from [this](https://gnu-mcu-eclipse.github.io/install/) install guide.
+
+### The xPack Manager
+
+This tool is a software package manager and it is used to help us get the necesarry depencencies.
+
+XPM runs using Node.js so grab that form [here](https://nodejs.org/en/). After installation, open a terminal and type `npm -v`. A reply with the version number means that the instalation was successful.
+
+XPM instalation instructions can be found [here](https://www.npmjs.com/package/xpm) and are OS specific. Entering `xpm --version` to your terminal should return the software version.
+
+### The ARM Toolchain
+
+Using XPM it is very easy to install the ARM toolchain. Enter the command `xpm install --global @gnu-mcu-eclipse/arm-none-eabi-gcc`.
+
+### Windows build tools
+
+If you are using windows you need to install this!
+
+`xpm install --global @gnu-mcu-eclipse/windows-build-tools`
+
+### Programer/Debugger Drivers
+
+Now its the time to install your programer's drivers. This tutorial was made using an ST-Link v2 which you can get from almost anywhere.
+If you have an ST-Link the drivers can be found [here](https://www.st.com/en/development-tools/stsw-link009.html) otherwise consult the manufuturer of your tool.
+
+### OpenOCD
+
+This dependency allows SWD access from GDB and it is essential for debugging. Run `xpm install --global @gnu-mcu-eclipse/openocd`.
+
+### Java
+
+Java is needed by Eclipse so please download it from [here](https://www.oracle.com/technetwork/java/javase/downloads/index.html).
+
+### GNU MCU Eclipse IDE
+
+Now its finally time to install the IDE. Use the Release page [here](https://github.com/gnu-mcu-eclipse/org.eclipse.epp.packages/releases/) to get the latest version.
+
+## Configuring Eclipse
+
+Open up the Eclipse IDE we just downloaded. To import our QMK directory select File -> Import -> C/C++ -> Existing code as Makefile Project. Select next and use Browse to select your QMK folder. In the tool-chain list select ARM Cross GCC and select Finish.
+
+Now you can see the QMK folder on the left hand side. Right click it and select Properties. On the left hand side, expand MCU and select ARM Toolchain Paths. Press xPack and OK. Repeat for OpenOCD Path  and if you are on windows for Build Tool Path. Select Apply and Close.
+
+Now its time to install the necessary MCU packages. Go to Packs perspective by selecting Window -> Open Perspective -> Others -> Packs. Now select the yellow refresh symbol next to the Packs tab. This will take a long time as it is requesting the MCU definitions from various places. If some of the links fail you can probably select Ignore.
+
+When this finishes you must find the MCU which we will be building/debugging for. In this example I will be using the STM32F3 series MCUs. On the left, select STMicroelectonics -> STM32F3 Series. On the middle window we can see the pack. Right click and select Install. Once that is done we can go back to the default perspective, Window -> Open Perspective -> Others -> C/C++.
+
+We need to let eclipse know the device we intent to build QMK on. Right click on the QMK folder -> Properties -> C/C++ Build -> Settings. Select the Devices tab and under devices select the appropriate variant of your MCU. For my example it is STM32F303CC
+
+While we are here let's setup the build command as well. Select C/C++ Build and then the Behavior tab. On the build command, replace `all` with your necessary make command. For example for a rev6 Planck with the default keymap this would be `planck/rev6:default`. Select Apply and Close.
+
+## Building
+
+If you have setup everything correctly pressing the hammer button should build the firmware for you and a .bin file should appear.
+
+## Debugging
+
+### Connecting the Debugger
+
+ARM MCUs use the Single Wire Debug (SWD) protocol which comprises of the clock (SWCLK) signal and the data (SWDIO) signal. Connecting this two wires and ground should be enough to allow full manipulation of the MCU. Here we assume that the keyboard will be powered though USB. The RESET signal is not necessary as we can manually assert it using the reset button. For a more advance setup, the SWO signal can be used which pipes printf and scanf asynchronously to the host but for our setup we will ignore it.
+
+NOTE: Make sure the SWCLK and SWDIO pins are not used in the matrix of your keyboard. If they are you can temporarily switch them for some other pins.
+
+### Configuring the Debugger
+
+Right click on your QMK folder, select Debug As -> Debug Configuration. Here double click on GDB OpenOCD Debugging. Select the debugger tab and enter the configuration necessary for your MCU. This might take some fiddling and googleing to find out. The default script for the STM32F3 is called stm32f3discovery.cfg. To let OpenOCD know, in the Config options enter `-f board/stm32f3discovery.cfg`.
+
+NOTE: In my case this configuration script requires editing to disable the reset assertion. The locations of the scripts can be found in the actual executable field usually under the path `openocd/version/.content/scripts/board`. Here I edited `reset_config srst_only` to `reset_config none`.
+
+Select Apply and Close.
+
+### Running the Debugger.
+
+Reset your keyboard.
+
+Press the bug icon and if all goes well you should soon find yourself in the debug perspective. Here the program counter will pause at the beginning of the main function and way for you to press Play. Most of the features of all debuggers work on ARM MCUs but for exact details google is your friend!
+
+
+Happy debugging!

-  
+### Setting Handedness
+
+One thing to remember, the side that the USB port is plugged into is always the master half. The side not plugged into USB is the slave.
+
+There are a few different ways to set handedness for split keyboards (listed in order of precedence):
+
+1. Set `SPLIT_HAND_PIN`: Reads a pin to determine handedness. If pin is high, it's the left side, if low, the half is determined to be the right side
+2. Set `EE_HANDS` and flash `eeprom-lefthand.eep`/`eeprom-righthand.eep` to each half
+3. Set `MASTER_RIGHT`: Half that is plugged into the USB port is determined to be the master and right half (inverse of the default)
+4. Default: The side that is plugged into the USB port is the master half and is assumed to be the left half. The slave side is the right half
+
+* `#define SPLIT_HAND_PIN B7` 
+  * For using high/low pin to determine handedness, low = right hand, high = left hand. Replace `B7` with the pin you are using. This is optional, and if you leave `SPLIT_HAND_PIN` undefined, then you can still use the EE_HANDS method or MASTER_LEFT / MASTER_RIGHT defines like the stock Let's Split uses.
+
+* `#define EE_HANDS` (only works if `SPLIT_HAND_PIN` is not defined)
+  * Reads the handedness value stored in the EEPROM after `eeprom-lefthand.eep`/`eeprom-righthand.eep` has been flashed to their respective halves.
+
+* `#define MASTER_RIGHT`
+  * Master half is defined to be the right half.
+
+### Other Options
+
 * `#define USE_I2C`
   * For using I2C instead of Serial (defaults to serial)
 
+* `#define SOFT_SERIAL_PIN D0`
+  * When using serial, define this. `D0` or `D1`,`D2`,`D3`,`E6`.
+
+* `#define MATRIX_ROW_PINS_RIGHT { <row pins> }`
+* `#define MATRIX_COL_PINS_RIGHT { <col pins> }`
+  * If you want to specify a different pinout for the right half than the left half, you can define `MATRIX_ROW_PINS_RIGHT`/`MATRIX_COL_PINS_RIGHT`. Currently, the size of `MATRIX_ROW_PINS` must be the same as `MATRIX_ROW_PINS_RIGHT` and likewise for the definition of columns.
+
+* `#define SELECT_SOFT_SERIAL_SPEED <speed>` (default speed is 1)
+  * Sets the protocol speed when using serial communication
+  * Speeds:
+    * 0: about 189kbps (Experimental only)

+
+## USB Endpoint Limitations
+
+In order to provide services over USB, QMK has to use USB endpoints.
+These are a finite resource: each microcontroller has only a certain number.
+This limits what features can be enabled together.
+If the available endpoints are exceeded, a build error is thrown.
+
+The following features can require separate endpoints:
+
+* `MOUSEKEY_ENABLE`
+* `EXTRAKEY_ENABLE`
+* `CONSOLE_ENABLE`
+* `NKRO_ENABLE`
+* `MIDI_ENABLE`
+* `RAW_ENABLE`
+* `VIRTSER_ENABLE`
+
+In order to improve utilisation of the endpoints, the HID features can be combined to use a single endpoint.
+By default, `MOUSEKEY`, `EXTRAKEY`, and `NKRO` are combined into a single endpoint.
+
+The base keyboard functionality can also be combined into the endpoint,
+by setting `KEYBOARD_SHARED_EP = yes`.
+This frees up one more endpoint,
+but it can prevent the keyboard working in some BIOSes,
+as they do not implement Boot Keyboard protocol switching.
+
+Combining the mouse also breaks Boot Mouse compatibility.
+The mouse can be uncombined by setting `MOUSE_SHARED_EP = no` if this functionality is required.

+# Persistent Configuration (EEPROM)
+
+This allows you to configure persistent settings for your keyboard.  These settings are stored in the EEPROM of your controller, and are retained even after power loss. The settings can be read with `eeconfig_read_kb` and `eeconfig_read_user`, and can be written to using `eeconfig_update_kb` and `eeconfig_update_user`. This is useful for features that you want to be able to toggle (like toggling rgb layer indication).  Additionally, you can use `eeconfig_init_kb` and `eeconfig_init_user` to set the default values for the EEPROM. 
+
+The complicated part here, is that there are a bunch of ways that you can store and access data via EEPROM, and there is no "correct" way to do this.  However, you only have a DWORD (4 bytes) for each function.
+
+Keep in mind that EEPROM has a limited number of writes. While this is very high, it's not the only thing writing to the EEPROM, and if you write too often, you can potentially drastically shorten the life of your MCU.
+
+* If you don't understand the example, then you may want to avoid using this feature, as it is rather complicated. 
+
+### Example  Implementation
+
+This is an example of how to add settings, and read and write it. We're using the user keymap for the example here.  This is a complex function, and has a lot going on.  In fact, it uses a lot of the above functions to work! 
+
+
+In your keymap.c file, add this to the top:
+```
+typedef union {
+  uint32_t raw;
+  struct {
+    bool     rgb_layer_change :1;
+  };
+} user_config_t;
+
+user_config_t user_config;
+```
+
+This sets up a 32 bit structure that we can store settings with in memory, and write to the EEPROM. Using this removes the need to define variables, since they're defined in this structure. Remember that `bool` (boolean) values use 1 bit, `uint8_t` uses 8 bits, `uint16_t` uses up 16 bits.  You can mix and match, but changing the order can cause issues, as it will change the values that are read and written. 
+
+We're using `rgb_layer_change`, for the `layer_state_set_*` function, and use `matrix_init_user` and `process_record_user` to configure everything. 
+
+Now, using the `matrix_init_user` code above, you want to add `eeconfig_read_user()` to it, to populate the structure you've just created. And you can then immediately use this structure to control functionality in your keymap.  And It should look like: 
+```
+void matrix_init_user(void) {
+  // Call the keymap level matrix init.
+
+  // Read the user config from EEPROM
+  user_config.raw = eeconfig_read_user();
+
+  // Set default layer, if enabled
+  if (user_config.rgb_layer_change) {
+    rgblight_enable_noeeprom();
+    rgblight_sethsv_noeeprom_cyan(); 
+    rgblight_mode_noeeprom(1);
+  }
+}
+```
+The above function will use the EEPROM config immediately after reading it, to set the default layer's RGB color. The "raw" value of it is converted in a usable structure based on the "union" that you created above. 
+
+```
+uint32_t layer_state_set_user(uint32_t state) {
+    switch (biton32(state)) {
+    case _RAISE:
+        if (user_config.rgb_layer_change) { rgblight_sethsv_noeeprom_magenta(); rgblight_mode_noeeprom(1); }
+        break;
+    case _LOWER:
+        if (user_config.rgb_layer_change) { rgblight_sethsv_noeeprom_red(); rgblight_mode_noeeprom(1); }
+        break;
+    case _PLOVER:
+        if (user_config.rgb_layer_change) { rgblight_sethsv_noeeprom_green(); rgblight_mode_noeeprom(1); }
+        break;
+    case _ADJUST:
+        if (user_config.rgb_layer_change) { rgblight_sethsv_noeeprom_white(); rgblight_mode_noeeprom(1); }
+        break;
+    default: //  for any other layers, or the default layer
+        if (user_config.rgb_layer_change) { rgblight_sethsv_noeeprom_cyan(); rgblight_mode_noeeprom(1); }
+        break;
+    }
+  return state;
+}
+```
+This will cause the RGB underglow to be changed ONLY if the value was enabled.  Now to configure this value, create a new keycode for `process_record_user` called `RGB_LYR` and `EPRM`. Additionally, we want to make sure that if you use the normal RGB codes, that it turns off  Using the example above, make it look this:
+```
+
+bool process_record_user(uint16_t keycode, keyrecord_t *record) {
+  switch (keycode) {
+    case FOO:
+      if (record->event.pressed) {
+        // Do something when pressed
+      } else {
+        // Do something else when release
+      }
+      return false; // Skip all further processing of this key
+    case KC_ENTER:
+        // Play a tone when enter is pressed
+        if (record->event.pressed) {
+            PLAY_NOTE_ARRAY(tone_qwerty);
+        }
+        return true; // Let QMK send the enter press/release events
+    case EPRM:
+        if (record->event.pressed) {
+            eeconfig_init(); // resets the EEPROM to default
+        }
+        return false;
+    case RGB_LYR:  // This allows me to use underglow as layer indication, or as normal
+        if (record->event.pressed) { 
+            user_config.rgb_layer_change ^= 1; // Toggles the status
+            eeconfig_update_user(user_config.raw); // Writes the new status to EEPROM
+            if (user_config.rgb_layer_change) { // if layer state indication is enabled, 
+                layer_state_set(layer_state);   // then immediately update the layer color
+            }
+        }
+        return false; break;
+    case RGB_MODE_FORWARD ... RGB_MODE_GRADIENT: // For any of the RGB codes (see quantum_keycodes.h, L400 for reference)
+        if (record->event.pressed) { //This disables layer indication, as it's assumed that if you're changing this ... you want that disabled
+            if (user_config.rgb_layer_change) {        // only if this is enabled 
+                user_config.rgb_layer_change = false;  // disable it, and 
+                eeconfig_update_user(user_config.raw); // write the setings to EEPROM
+            }
+        }
+        return true; break;
+    default:
+      return true; // Process all other keycodes normally
+  }
+}
+```
+And lastly, you want to add the `eeconfig_init_user` function, so that when the EEPROM is reset, you can specify default values, and even custom actions. For example, if you want to set rgb layer indication by default, and save the default valued. 
+
+```
+void eeconfig_init_user(void) {  // EEPROM is getting reset! 
+  user_config.rgb_layer_change = true; // We want this enabled by default
+  eeconfig_update_user(user_config.raw); // Write default value to EEPROM now
+
+  // use the non noeeprom versions, to write these values to EEPROM too
+  rgblight_enable(); // Enable RGB by default
+  rgblight_sethsv_cyan();  // Set it to CYAN by default
+  rgblight_mode(1); // set to solid by default
+}
+```
+
+And you're done.  The RGB layer indication will only work if you want it to. And it will be saved, even after unplugging the board. And if you use any of the RGB codes, it will disable the layer indication, so that it stays on the mode and color that you set it to.

+
+You can also chain them, for example `LCTL(LALT(KC_DEL))` makes a key that sends Control+Alt+Delete with a single keypress.
+
+# Mod-Tap
+
+The Mod-Tap key `MT(mod, kc)` acts like a modifier when held, and a regular keycode when tapped. In other words, you can have a key that sends Escape when you tap it, but functions as a Control or Shift key when you hold it down.
+
+The modifiers this keycode and `OSM()` accept are prefixed with `MOD_`, not `KC_`:
+
+|Modifier  |Description                             |
+|----------|----------------------------------------|
+|`MOD_LCTL`|Left Control                            |
+|`MOD_LSFT`|Left Shift                              |
+|`MOD_LALT`|Left Alt                                |
+|`MOD_LGUI`|Left GUI (Windows/Command/Meta key)     |
+|`MOD_RCTL`|Right Control                           |
+|`MOD_RSFT`|Right Shift                             |
+|`MOD_RALT`|Right Alt (AltGr)                       |
+|`MOD_RGUI`|Right GUI (Windows/Command/Meta key)    |
+|`MOD_HYPR`|Hyper (Left Control, Shift, Alt and GUI)|
+|`MOD_MEH` |Meh (Left Control, Shift, and Alt)      |
+
+You can combine these by ORing them together like so:
 
-`MT(mod, kc)` - is *mod* (modifier key - MOD_LCTL, MOD_LSFT) when held, and *kc* when tapped. In other words, you can have a key that sends Esc (or the letter O or whatever) when you tap it, but works as a Control key or a Shift key when you hold it down.
+```c
+MT(MOD_LCTL | MOD_LSFT, KC_ESC)
+```
 
-These are the values you can use for the `mod` in `MT()` and `OSM()`:
+This key would activate Left Control and Left Shift when held, and send Escape when tapped.
 
-  * MOD_LCTL
-  * MOD_LSFT
-  * MOD_LALT
-  * MOD_LGUI
-  * MOD_RCTL
-  * MOD_RSFT
-  * MOD_RALT
-  * MOD_RGUI
-  * MOD_HYPR
-  * MOD_MEH
+For convenience, QMK includes some Mod-Tap shortcuts to make common combinations more compact in your keymap:
 
-These can also be combined like `MOD_LCTL | MOD_LSFT` e.g. `MT(MOD_LCTL | MOD_LSFT, KC_ESC)` which would activate Control and Shift when held, and send Escape when tapped.

-  * `LCAG_T(kc)` - is CtrlAltGui when held and *kc* when tapped
-  * `MEH_T(kc)` - is like Hyper, but not as cool -- does not include the Cmd/Win key, so just sends Alt+Ctrl+Shift.
+Unfortunately, these keycodes cannot be used in Mod-Taps or Layer-Taps, since any modifiers specified in the keycode are ignored.
 
-?> Due to the way that keycodes are structured, any modifiers specified as part of `kc`, such as `LCTL()` or `KC_LPRN`, will only activate when held instead of tapped.
+Additionally, you may run into issues when using Remote Desktop Connection on Windows. Because these codes send shift very fast, Remote Desktop may miss the codes.
 
-?> Additionally, if there is at least one right-handed modifier, any other modifiers in a chain of functions will turn into their right-handed equivalents, so it is not possible to "mix and match" the two.
+To fix this, open Remote Desktop Connection, click on "Show Options", open the the "Local Resources" tab. In the keyboard section, change the drop down to "On this Computer". This will fix the issue, and allow the characters to work correctly.

+
+# Tap-Hold Configuration Options
+
+While Tap-Hold options are fantastic, they are not without their issues.  We have tried to configure them with reasonal defaults, but that may still cause issues for some people. 
+
+These options let you modify the behavior of the Tap-Hold keys.
+
+## Permissive Hold
 
 As of [PR#1359](https://github.com/qmk/qmk_firmware/pull/1359/), there is a new `config.h` option:
 
-```
+```c
 #define PERMISSIVE_HOLD
 ```
 
-This makes it easier for fast typists to use dual-function keys. Without this, if you let go of a held key inside the tapping term, it won't register.
+This makes tap and hold keys (like Mod Tap) work better for fast typist, or for high `TAPPING_TERM` settings. 
 
-Example: (Tapping Term = 200ms)
+If you press a Mod Tap key, tap another key (press and release) and then release the Mod Tap key, all within the tapping term, it will output the "tapping" function for both keys.
 
-- SHFT_T(KC_A) Down
-- KC_X Down
-- KC_X Up
-- SHFT_T(KC_A) Up
+For Instance:
 
-With defaults, if above is typed within tapping term, this will emit `ax`. With permissive hold, if above is typed within tapping term, this will emit `X` (so, Shift+X).
+- `SHFT_T(KC_A)` Down
+- `KC_X` Down
+- `KC_X` Up
+- `SHFT_T(KC_A)` Up
 
-# Mod tap interrupt
+Normally, if you do all this within the `TAPPING_TERM` (default: 200ms) this will be registered as `ax` by the firmware and host system. With permissive hold enabled, this modifies how this is handled by considering the Mod Tap keys as a Mod if another key is tapped, and would registered as `X` (`SHIFT`+`x`). 
 
-When a dual role key used for a modifier is quickly followed by another keys, it is interpreted as held even before the tapping term elapsed.  This is a problem if a key is used for example inside a rolling combo because the second key will be pressed before the first key is released.
+?> If you have `Ignore Mod Tap Interrupt` enabled, as well, this will modify how both work. The regular key has the modifier added if the first key is released first or if both keys are held longer than the `TAPPING_TERM`.
 
-For example, when trying to type the rolling combo "zx" and z being configured to send Ctrl when hold, z rapidly followed by x actually sends Ctrl-x. That's bad.
+## Ignore Mod Tap Interrupt
 
-You can disable this behavior by defining `IGNORE_MOD_TAP_INTERRUPT` in `config.h`.
+To enable this setting, add this to your `config.h`:
 
-Note that this only concerns modifiers and not layer switching keys.
+```c
+#define IGNORE_MOD_TAP_INTERRUPT
+```
+
+Similar to Permissive Hold, this alters how the firmware processes input for fast typist. If you press a Mod Tap key, press another key, release the Mod Tap key, and then release the normal key, it would normally output the "tapping" function for both keys. This may not be desirable for rolling combo keys. 
+
+Setting `Ignore Mod Tap Interrupt` requires  holding both keys for the `TAPPING_TERM` to trigger the hold function (the mod).
+
+For Instance:
+
+- `SHFT_T(KC_A)` Down
+- `KC_X` Down
+- `SHFT_T(KC_A)` Up
+- `KC_X` Up
+
+Normally, this would send `X` (`SHIFT`+`x`). With `Ignore Mod Tap Interrupt` enabled, holding both keys are required for the `TAPPING_TERM` to register the hold action. A quick tap will output `ax` in this case, while a hold on both will still output `X`  (`SHIFT`+`x`).
+
+
+?> __Note__: This only concerns modifiers and not layer switching keys.
+
+?> If you have `Permissive Hold` enabled, as well, this will modify how both work. The regular key has the modifier added if the first key is released first or if both keys are held longer than the `TAPPING_TERM`.
 
-# Hold after tap
+## Tapping Force Hold
 
-When the user holds a key after tap, this repeats the tapped key rather to hold a modifier key.  This allows to use auto repeat for the tapped key.  If you prefer to hold a modifier instead, define `TAPPING_FORCE_HOLD` in `config.h`.
+To enable `tapping force hold`, add the following to your `config.h`: 
+
+```c
+#define TAPPING_FORCE_HOLD
+```

-# Retro Tapping
+## Retro Tapping
+
+To enable `retro tapping`, add the following to your `config.h`: 
+
+```c
+#define RETRO_TAPPING
+```
 
-When you hold a dual function key, and haven't pressed anything when you release the key, normally nothing happens.  However, if you enable this, if you release the key without pressing another key, it will send the original key, even if it is outside of the tapping term. 
+Holding and releasing a dual function key without pressing another key will result in nothing happening. With retro tapping enabled, releasing the key without pressing another will send the original keycode even if it is outside the tapping term.
 
-For instance, if you're using `LT(2, KC_SPACE)`, if you hold the key, don't hit anything else and then release it, normally, nothing happens. But with `RETRO_TAPPING` defined in your `config.h`, it will send `KC_SPACE`.

+### Adafruit BLE SPI Friend
+Currently The only bluetooth chipset supported by QMK is the Adafruit Bluefruit SPI Friend. It's a Nordic nRF5182 based chip running Adafruit's custom firmware. Data is transmitted via Adafruit's SDEP over Hardware SPI. The [Feather 32u4 Bluefruit LE](https://www.adafruit.com/product/2829) is supported as it's an AVR mcu connected via SPI to the Nordic BLE chip with Adafruit firmware. If Building a custom board with the SPI friend it would be easiest to just use the pin selection that the 32u4 feather uses but you can change the pins in the config.h options with the following defines:
+* #define AdafruitBleResetPin D4
+* #define AdafruitBleCSPin    B4
+* #define AdafruitBleIRQPin   E6
+
+A Bluefruit UART friend can be converted to an SPI friend, however this [requires](https://github.com/qmk/qmk_firmware/issues/2274) some reflashing and soldering directly to the MDBT40 chip.

+## Adafruit EZ-Key hid
 This requires [some hardware changes](https://www.reddit.com/r/MechanicalKeyboards/comments/3psx0q/the_planck_keyboard_with_bluetooth_guide_and/?ref=search_posts), but can be enabled via the Makefile. The firmware will still output characters via USB, so be aware of this when charging via a computer. It would make sense to have a switch on the Bluefruit to turn it off at will.

+# Bootmagic Lite
+
+In addition to the full blown Bootmagic feature, is the Bootmagic Lite feature that only handles jumping into the bootloader.  This is great for boards that don't have a physical reset button but you need a way to jump into the bootloader, and don't want to deal with the headache that Bootmagic can cause.
+
+To enable this version of Bootmagic, you need to enable it in your `rules.mk` with:
+
+```make
+BOOTMAGIC_ENABLE = lite
+```
+
+Additionally, you may want to specify which key to use.  This is especially useful for keyboards that have unusual matrices.  To do so, you need to specify the row and column of the key that you want to use. Add these entries to your `config.h` file:
+
+```c
+#define BOOTMAGIC_LITE_ROW 0
+#define BOOTMAGIC_LITE_COLUMN 1
+```
+
+By default, these are set to 0 and 0, which is usually the "ESC" key on a majority of keyboards.
+
+And to trigger the bootloader, you hold this key down when plugging the keyboard in. Just the single key. 
+
+## Advanced Bootmagic Lite
+
+The `bootmagic_lite` function is defined weakly, so that you can replace this in your code, if you need.  A great example of this is the Zeal60 boards that have some additional handling needed.
+
+To replace the function, all you need to do is add something like this to your code:
+
+```c
+void bootmagic_lite(void) {
+    matrix_scan();
+    wait_ms(DEBOUNCING_DELAY * 2);
+    matrix_scan();
+
+    if (matrix_get_row(BOOTMAGIC_LITE_ROW) & (1 << BOOTMAGIC_LITE_COLUMN)) {
+      // Jump to bootloader.
+      bootloader_jump();
+    }
+}
+```
+
+You can additional feature here. For instance, resetting the eeprom or requiring additional keys to be pressed to trigger bootmagic.  Keep in mind that `bootmagic_lite` is called before a majority of features are initialized in the firmware.

+# Combos
+
+The Combo feature is a chording type solution for adding custom actions.  It lets you hit multiple keys at once and produce a different effect.  For instance, hitting `A` and `S` within the tapping term would hit `ESC` instead, or have it perform even more complex tasks.
+
+To enable this feature, yu need to add `COMBO_ENABLE = yes` to your `rules.mk`.
+
+Additionally, in your `config.h`, you'll need to specify the number of combos that you'll be using, by adding `#define COMBO_COUNT 1` (replacing 1 with the number that you're using).
+<!-- At this time, this is necessary -->
+
+Also, by default, the tapping term for the Combos is set to the same value as `TAPPING_TERM` (200 by default on most boards). But you can specify a different value by defining it in your `config.h`.  For instance: `#define COMBO_TERM 300` would set the time out period for combos to 300ms.
+
+Then, your `keymap.c` file, you'll need to define a sequence of keys, terminated with `COMBO_END`, and a structure to list the combination of keys, and it's resulting action.
+
+```c
+const uint16_t PROGMEM test_combo[] = {KC_A, KC_B, COMBO_END};
+combo_t key_combos[COMBO_COUNT] = {COMBO(test_combo, KC_ESC)};
+```
+
+This will send "Escape" if you hit the A and B keys.
+
+!> This method only supports [basic keycodes](keycodes_basic.md). See the examples for more control.
+!> You cannot reuse (share) keys in combos. Each key should only belong to a single combo.  
+
+## Examples
+
+If you want to add a list, then you'd use something like this:
+
+```c
+enum combos {
+  AB_ESC,
+  JK_TAB
+}
+const uint16_t PROGMEM ab_combo[] = {KC_A, KC_B, COMBO_END};
+const uint16_t PROGMEM jk_combo[] = {KC_J, KC_K, COMBO_END};
+
+combo_t key_combos[COMBO_COUNT] = {
+  [AB_ESC] = COMBO(ab_combo, KC_ESC),
+  [JK_TAB] = COMBO(jk_combo, KC_TAB)
+};
+```
+
+For a more complicated implementation, you can use the `process_combo_event` function to add custom handling.
+
+```c
+enum combo_events {
+  ZC_COPY,
+  XV_PASTE
+  };
+
+const uint16_t PROGMEM copy_combo[] = {KC_Z, KC_C, COMBO_END};
+const uint16_t PROGMEM paste_combo[] = {KC_X, KC_V, COMBO_END};
+
+combo_t key_combos[COMBO_COUNT] = {
+  [ZC_COPY] = COMBO_ACTION(copy_combo),
+  [XV_PASTE] = COMBO_ACTION(paste_combo),
+};
+
+void process_combo_event(uint8_t combo_index, bool pressed) {
+  switch(combo_index) {
+    case ZC_COPY:
+      if (pressed) {
+        register_code(KC_LCTL);
+        register_code(KC_C);
+        unregister_code(KC_C);
+        unregister_code(KC_LCTL);
+      }
+      break;
+
+    case XV_PASTE:
+      if (pressed) {
+        register_code(KC_LCTL);
+        register_code(KC_V);
+        unregister_code(KC_V);
+        unregister_code(KC_LCTL);
+      }
+      break;
+  }
+}
+```
+
+This will send Ctrl+C if you hit Z and C, and Ctrl+V if you hit X and V.  But you could change this to do stuff like change layers, play sounds, or change settings.
+
+## Additional Configuration
+
+If you're using long combos, or even longer combos, you may run into issues with this, as the structure may not be large enough to accommodate what you're doing.
+
+In this case, you can add either `#define EXTRA_LONG_COMBOS` or `#define EXTRA_EXTRA_LONG_COMBOS` in your `config.h` file.
+
+You may also be able to enable action keys by defining `COMBO_ALLOW_ACTION_KEYS`.

 That's what `KC_LEAD` does. Here's an example:

-2. Include the line `#define LEADER_TIMEOUT 300` somewhere in your keymap.c file, probably near the top. The 300 there is 300ms -- that's how long you have for the sequence of keys following the leader. You can tweak this value for comfort, of course.

+2. Include the line `#define LEADER_TIMEOUT 300` in your `config.h`. This sets the timeout for the `KC_LEAD` key.  Specifically, when you press the `KC_LEAD` key, you only have a certain amount of time to complete the Leader Key sequence.  The `300` here sets that to 300ms, and you can increase this value to give you more time to hit the sequence. But any keys pressed during this timeout are intercepted and not sent, so you may want to keep this value low. .  
+   * By default, this timeout is how long after pressing `KC_LEAD` to complete your entire sequence. This may be very low for some people. So you may want to increase this timeout.  Optionally, you may want to enable the `LEADER_PER_KEY_TIMING` option, which resets the timeout after each key is tapped.  This allows you to maintain a low value here, but still be able to use the longer sequences.   To enable this option, add `#define LEADER_PER_KEY_TIMING` to your `config.h`.
+3. Within your `matrix_scan_user` function, add something like this:

 As you can see, you have a few function. You can use `SEQ_ONE_KEY` for single-key sequences (Leader followed by just one key), and `SEQ_TWO_KEYS`, `SEQ_THREE_KEYS` up to `SEQ_FIVE_KEYS` for longer sequences.
 
 Each of these accepts one or more keycodes as arguments. This is an important point: You can use keycodes from **any layer on your keyboard**. That layer would need to be active for the leader macro to fire, obviously.
+
+## Adding Leader Key Support in the `rules.mk`
+
+To add support for Leader Key you simply need to add a single line to your keymap's `rules.mk`:
+
+```make
+LEADER_ENABLE = yes
+```
+
+## Per Key Timing on Leader keys
+
+Rather than relying on an incredibly high timeout for long leader key strings or those of us without 200wpm typing skills, we can enable per key timing to ensure that each key pressed provides us with more time to finish our stroke. This is incredibly helpful with leader key emulation of tap dance (read: multiple taps of the same key like C, C, C).
+
+In order to enable this, place this in your `config.h`:
+```c
+#define LEADER_PER_KEY_TIMING
+```
+
+After this, it's recommended that you lower your `LEADER_TIMEOUT` to something less that 300ms.
+
+```c
+#define LEADER_TIMEOUT 250
+```
+
+Now, something like this won't seem impossible to do without a 1000MS leader key timeout:
+
+```c
+SEQ_THREE_KEYS(KC_C, KC_C, KC_C) {
+  SEND_STRING("Per key timing is great!!!");
+}
+```
+
+## Strict Key Processing
+
+By default, the Leader Key feature will filter the keycode out of [`Mod-Tap`](feature_advanced_keycodes.md#mod-tap) and [`Layer Tap`](feature_advanced_keycodes.md#switching-and-toggling-layers) functions when checking for the Leader sequences. That means if you're using `LT(3, KC_A)`, it will pick this up as `KC_A` for the sequence, rather than `LT(3, KC_A)`, giving a more expected behavior for newer users.
+
+While, this may be fine for most, if you want to specify the whole keycode (eg, `LT(3, KC_A)` from the example above) in the sequence, you can enable this by added `#define LEADER_KEY_STRICT_KEY_PROCESSING` to your `config.h` file.  This well then disable the filtering, and you'll need to specify the whole keycode.
+
+## Customization 
+
+The Leader Key feature has some additional customization to how the Leader Key feature works.  It has two functions that can be called at certain parts of the process.  Namely `leader_start()` and `leader_end()`.
+
+The `leader_start()` function is called when you tap the `KC_LEAD` key, and the `leader_end()` function is called when either the leader sequence is completed, or the leader timeout is hit. 
+
+You can add these functions to your code (`keymap.c` usually) to add feedback to the Leader sequences (such as beeping or playing music).
+
+```c
+void leader_start(void) {
+  // sequence started
+}
+
+void leader_end(void) {
+  // sequence ended (no success/failuer detection)
+}
+```
+
+### Example
+
+This example will play the Mario "One Up" sound when you hit `KC_LEAD` to start the Leader Sequence, and will play "All Star" if it completes successfully or "Rick Roll" you if it fails. 
+
+```c

+Supports Unicode up to `0x10FFFF` (all possible code points). You need to maintain a separate mapping table `const uint32_t PROGMEM unicode_map[] = {...}` in your keymap file. The keycode function is `X(n)`, where _n_ is an array index into the mapping table.
+
+And you may want to have an enum to make reference easier.  So you'd want to add something like this to your keymap:
+
+```c
+enum unicode_names {
+  BANG,
+  IRONY,
+  SNEK,
+};
+
+const uint32_t PROGMEM unicode_map[] = {
+  [BANG]    = 0x203D,  // ‽
+  [IRONY]   = 0x2E2E,  // ⸮
+  [SNEK]    = 0x1F40D, // 🐍
+};
+```
+
+Make sure that the order for both matches.
 
 ## UCIS_ENABLE
 
-TBD
+Supports Unicode up to `0x10FFFF` (all possible code points). As with `UNICODEMAP`, you may want to maintain a mapping table in your keymap file. However, there are no built-in keycodes for this feature — you will have to add a keycode or function that calls `qk_ucis_start()`. Once it's been called, you can type the mnemonic for your character, then hit Space or Enter to complete it or Esc to cancel. If the mnemonic matches an entry in your table, the typed text will automatically be erased and the corresponding Unicode sequence inserted.
+
+For instance, you would need to have a table like this in your keymap:
+
+```c
+const qk_ucis_symbol_t ucis_symbol_table[] = UCIS_TABLE
+(
+ UCIS_SYM("poop", 0x1f4a9),
+ UCIS_SYM("rofl", 0x1f923),
+ UCIS_SYM("kiss", 0x1f619)
+);
+```
+
+You run the function, and then type "rofl" and hit enter, it should backspace remove "rofl" and input the `0x1f923` unicode.
+
+### Customization
+
+There are several functions that you can add to your keymap to customize the functionality of this feature.
+
+* `void qk_ucis_start_user(void)` - This runs when you run the "start" function, and can be used to provide feedback. By default, it types out a keyboard emoji.
+* `void qk_ucis_success(uint8_t symbol_index)` - This runs when the unicode input has matched something, and has completed. Default doesn't do anything.
+* `void qk_ucis_symbol_fallback (void)` - This runs if the input text doesn't match anything.  The default function falls back to trying that input as a unicode code.
+
+You can find the default implementations of these functions in [`process_ucis.c`](https://github.com/qmk/qmk_firmware/blob/master/quantum/process_keycode/process_ucis.c).
+
+## Input Modes
+
+Unicode input in QMK works by inputting a sequence of characters to the OS, sort of like a macro. Unfortunately, the way this is done differs for each platform. Specifically, each platform requires a different combination of keys to trigger Unicode input. Therefore, a corresponding input mode has to be set in QMK.
+
+The following input modes are available:
+
+* **`UC_OSX`**: Mac OS X built-in Unicode hex input. Supports code points up to `0xFFFF` (`0x10FFFF` with `UNICODEMAP`).
+
+  To enable, go to _System Preferences > Keyboard > Input Sources_, add _Unicode Hex Input_ to the list (it's under _Other_), then activate it from the input dropdown in the Menu Bar.
+  By default, this mode uses the left Option key (`KC_LALT`), but this can be changed by defining [`UNICODE_OSX_KEY`](#input-key-configuration) with another keycode.
+
+* **`UC_LNX`**: Linux built-in IBus Unicode input. Supports all possible code points (`0x10FFFF`).
+
+  Enabled by default and works almost anywhere on IBus-enabled distros. Without IBus, this mode works under GTK apps, but rarely anywhere else.
+
+* **`UC_WIN`**: _(not recommended)_ Windows built-in hex numpad Unicode input. Supports code points up to `0xFFFF`.
+
+  To enable, create a registry key under `HKEY_CURRENT_USER\Control Panel\Input Method\EnableHexNumpad` of type `REG_SZ` called `EnableHexNumpad` and set its value to `1`. This can be done from the Command Prompt by running `reg add "HKCU\Control Panel\Input Method" -v EnableHexNumpad -t REG_SZ -d 1` with administrator privileges. Afterwards, reboot.
+  This mode is not recommended because of reliability and compatibility issues; use the `UC_WINC` mode instead.
+
+* **`UC_BSD`**: _(non implemented)_ Unicode input under BSD. Not implemented at this time. If you're a BSD user and want to help add support for it, please [open an issue on GitHub](https://github.com/qmk/qmk_firmware/issues).
+
+* **`UC_WINC`**: Windows Unicode input using [WinCompose](https://github.com/samhocevar/wincompose). As of v0.8.2, supports code points up to `0xFFFFF`.
+
+  To enable, install the [latest release](https://github.com/samhocevar/wincompose/releases/latest). Once installed, WinCompose will automatically run on startup. Works reliably under all version of Windows supported by the app.
+  By default, this mode uses the right Alt key (`KC_RALT`), but this can be changed in the WinCompose settings and by defining [`UNICODE_WINC_KEY`](#input-key-configuration) with another keycode.
+
+### Switching Input Modes
+
+There are two ways to set the input mode for Unicode: by keycode or by function. Keep in mind that both methods write to persistent storage (EEPROM), and are loaded each time the keyboard starts. So once you've set it the first time, you don't need to set it again unless you want to change it, or you've reset the EEPROM settings.
 
-Unicode input in QMK works by inputing a sequence of characters to the OS,
-sort of like macro. Unfortunately, each OS has different ideas on how Unicode is inputted.
+You can switch the input mode at any time by using one of the following keycodes. The easiest way is to add the ones you use to your keymap.
 
-This is the current list of Unicode input method in QMK:
+|Keycode                |Alias    |Input mode   |Description                              |
+|-----------------------|---------|-------------|-----------------------------------------|
+|`UNICODE_MODE_FORWARD` |`UC_MOD` |             |Cycles forwards through the available modes. [(Disabled by default)](#input-method-cycling)|
+|`UNICODE_MODE_REVERSE` |`UC_RMOD`|             |Cycles forwards through the available modes. [(Disabled by default)](#input-method-cycling)|
+|`UNICODE_MODE_OSX`     |`UC_M_OS`|`UC_OSX`     |Switch to Mac OS X input.                |
+|`UNICODE_MODE_LNX`     |`UC_M_LN`|`UC_LNX`     |Switch to Linux input.                   |
+|`UNICODE_MODE_WIN`     |`UC_M_WI`|`UC_WIN`     |Switch to Windows input.                 |
+|`UNICODE_MODE_BSD`     |`UC_M_BS`|`UC_BSD`     |Switch to BSD input (not implemented).   |
+|`UNICODE_MODE_WINC`    |`UC_M_WC`|`UC_WINC`    |Switch to Windows input using WinCompose.|
 
-* UC_OSX: MacOS Unicode Hex Input support. Works only up to 0xFFFF. Disabled by default. To enable: go to System Preferences -> Keyboard -> Input Sources, and enable Unicode Hex.
-* UC_OSX_RALT: Same as UC_OSX, but sends the Right Alt key for unicode input
-* UC_LNX: Unicode input method under Linux. Works up to 0xFFFFF. Should work almost anywhere on ibus enabled distros. Without ibus, this works under GTK apps, but rarely anywhere else.
-* UC_WIN: (not recommended) Windows built-in Unicode input. To enable: create registry key under `HKEY_CURRENT_USER\Control Panel\Input Method\EnableHexNumpad` of type `REG_SZ` called `EnableHexNumpad`, set its value to 1, and reboot. This method is not recommended because of reliability and compatibility issue, use WinCompose method below instead.
-* UC_WINC: Windows Unicode input using WinCompose. Requires [WinCompose](https://github.com/samhocevar/wincompose). Works reliably under many (all?) variations of Windows.
+You can also switch the input mode by calling `set_unicode_input_mode(x)` in your code, where _x_ is one of the above input mode constants (e.g. `UC_LNX`). Since the function only needs to be called once, it's recommended that you do it in `eeconfig_init_user` (or a similar function). For example:
 
-# Additional Language Support
+```c
+void eeconfig_init_user(void) {
+  set_unicode_input_mode(UC_LNX);
+}
+```
+
+### Audio Feedback
+
+If you have the [Audio feature](feature_audio.md) enabled on the board, you can set melodies to be played when you press the above keys. That way you can have some audio feedback when switching input modes.
+
+For instance, you can add these definitions to your `config.h` file:
+
+```c
+#define UNICODE_SONG_OSX  COIN_SOUND
+#define UNICODE_SONG_LNX  UNICODE_LINUX
+#define UNICODE_SONG_BSD  MARIO_GAMEOVER
+#define UNICODE_SONG_WIN  UNICODE_WINDOWS
+#define UNICODE_SONG_WINC UNICODE_WINDOWS
+```
+
+### Additional Customization
+
+Because Unicode is such a large and variable feature, there are a number of options that you can customize to work better on your system. 
+
+#### Start and Finish input functions
+
+The functions for starting and finishing Unicode input on your platform can be overridden locally. Possible uses include customizing input mode behavior if you don't use the default keys, or adding extra visual/audio feedback to Unicode input.
+
+* `void unicode_input_start(void)` – This sends the initial sequence that tells your platform to enter Unicode input mode. For example, it presses Ctrl+Shift+U on Linux and holds the Option key on Mac.
+* `void unicode_input_finish(void)` – This is called to exit Unicode input mode, for example by pressing Space or releasing the Option key.
+
+You can find the default implementations of these functions in [`process_unicode_common.c`](https://github.com/qmk/qmk_firmware/blob/master/quantum/process_keycode/process_unicode_common.c).
+
+
+#### Input Key Configuration
+
+Additionally, you can customize the keys used to trigger the unicode input for macOS and WinCompose by adding defines to your `config.h`
+
+```c
+#define UNICODE_OSX_KEY  KC_LALT
+#define UNICODE_WINC_KEY KC_RALT
+```
+
+#### Input Method Cycling
+
+Also, you can choose which input methods are availble for cycling through.  By default, this is disabled. But if you want to enabled it, then limiting it to just those modes makes sense.  Note that `UNICODE_SELECTED_MODES` define is comma delimited.
+
+```c
+#define UNICODE_SELECTED_MODES UC_OSX, UC_LNX, UC_WIN, UC_BSD, UC_WINC
+```
+
+## `send_unicode_hex_string`
+
+To type multiple characters for things like (ノಠ痊ಠ)ノ彡┻━┻, you can use `send_unicode_hex_string()` much like `SEND_STRING()` except you would use hex values separate by spaces.
+For example, the table flip seen above would be `send_unicode_hex_string("0028 30CE 0CA0 75CA 0CA0 0029 30CE 5F61 253B 2501 253B")`
+
+There are many ways to get a hex code, but an easy one is [this site](https://r12a.github.io/app-conversion/). Just make sure to convert to hexadecimal, and that is your string.
+
+## Additional Language Support
 
 In `quantum/keymap_extras/`, you'll see various language files - these work the same way as the alternative layout ones do. Most are defined by their two letter country/language code followed by an underscore and a 4-letter abbreviation of its name. `FR_UGRV` which will result in a `ù` when using a software-implemented AZERTY layout. It's currently difficult to send such characters in just the firmware.

+The `rules.mk` is one of the two files that gets processed automatically.  This is how you add additional source files (such as  `<name>.c`) will be added when compiling.
 
-So you should use the `config.h` for QMK settings, and the `<name>.h` file for user or keymap specific settings.
+It's highly recommended that you use `<name>.c` as the default source file to be added. And to add it, you need to add it the SRC in `rules.mk` like this:
 
-`/users/<name>/rules.mk` will be included in the build _after_ the `rules.mk` from your keymap. This allows you to have features in your userspace `rules.mk` that depend on individual QMK features that may or may not be available on a specific keyboard. For example, if you have RGB control features shared between all your keyboards that support RGB lighting, you can `define RGB_ENABLE` in your keymap `rules.mk` and then check for the variable in your userspace `rules.mk` like this:
+    SRC += <name>.c
+
+Additional files may be added in the same way - it's recommended you have one named `<name>`.c/.h to start off with, though. 
+
+The `/users/<name>/rules.mk` file will be included in the build _after_ the `rules.mk` from your keymap. This allows you to have features in your userspace `rules.mk` that depend on individual QMK features that may or may not be available on a specific keyboard. 
+
+For example, if you have RGB control features shared between all your keyboards that support RGB lighting, you can add support for that if the RGBLIGHT feature is enabled:
 ```make
-ifdef RGB_ENABLE
-    # Include my fancy rgb functions source here
+ifeq ($(strip $(RGBLIGHT_ENABLE)), yes)
+  # Include my fancy rgb functions source here
+  SRC += cool_rgb_stuff.c
 endif
 ```
-Because of this, any time you turn on QMK features in your `users/<name>/rules.mk`, you should conditionally enable them only if the flag isn't already defined, like this:
+
+Alternatively, you can `define RGB_ENABLE` in your keymap's `rules.mk` and then check for the variable in your userspace's `rules.mk` like this:
 ```make
-ifndef TAP_DANCE_ENABLE
-    TAP_DANCE_ENABLE = yes
+ifdef RGB_ENABLE
+  # Include my fancy rgb functions source here
+  SRC += cool_rgb_stuff.c
 endif
 ```
-This will ensure that you can explicitly turn off features for an individual keymap.
 
-## Readme
+### Override default userspace
+
+By default the userspace used will be the same as the keymap name. In some situations this isn't desirable. For instance, if you use the [layout](feature_layouts.md) feature you can't use the same name for different keymaps (e.g. ANSI and ISO). You can name your layouts `mylayout-ansi` and `mylayout-iso` and add the following line to your layout's `rules.mk`:
+
+```
+USER_NAME := mylayout
+```
+
+This is also useful if you have multiple different keyboards with different features physically present on the board (such as one with RGB Lights, and one with Audio, or different number of LEDs, or connected to a different PIN on the controller).
+
+## Configuration Options (`config.h`)
+
+Additionally, `config.h` here will be processed like the same file in your keymap folder.  This is handled separately from the `<name>.h` file.
+
+The reason for this, is that `<name>.h` won't be added in time to add settings (such as `#define TAPPING_TERM 100`), and including the `<name.h>` file in any `config.h` files will result in compile issues.
+
+!>You should use the `config.h` for [configuration options](config_options.md), and the `<name>.h` file for user or keymap specific settings (such as the enum for layer or keycodes)

+
+
+## Customized Functions
+
+QMK has a bunch of [functions](custom_quantum_functions.md) that have [`_quantum`, `_kb`, and `_user` versions](custom_quantum_functions.md#a-word-on-core-vs-keyboards-vs-keymap) that you can use.  You will pretty much always want to use the user version of these functions.  But the problem is that if you use them in your userspace, then you don't have a version that you can use in your keymap. 
+
+However, you can actually add support for keymap version, so that you can use it in both your userspace and your keymap! 
 
-If you do add a `config,h` file, you want to make sure that it only gets processed once.  So you may want to start off with something like this:
 
+For instance, lets looks at the `layer_state_set_user` function.  Lets enable the [Tri Layer State](ref_functions.md#olkb-tri-layers) functionalitly to all of our boards, and then still have your `keymap.c` still able to use this functionality. 
+
+In your `<name.c>` file, you'd want to add this: 
 ```c
-#ifndef USERSPACE_CONFIG_H
-#define USERSPACE_CONFIG_H
+__attribute__ ((weak))
+uint32_t layer_state_set_keymap (uint32_t state) {
+  return state;
+}
+
+uint32_t layer_state_set_user (uint32_t state) {
+  state = update_tri_layer_state(state, 2, 3, 5);
+  return layer_state_set_keymap (state);
+}
+```
+The `__attribute__ ((weak))` part tells the compiler that this is a placeholder function that can then be replaced by a version in your `keymap.c`.  That way, you don't need to add it to your `keymap.c`, but if you do, you won't get any conflicts because the function is the same name. 
 
-// Put normal config.h settings here:
+The `_keymap` part here doesn't matter, it just needs to be something other than `_quantum`, `_kb`, or `_user`, since those are already in use. So you could use `layer_state_set_mine`, `layer_state_set_fn`, or anything else.
 
-#endif // !USERSPACE_CONFIG_H
+You can see a list of this and other common functions in [`template.c`](https://github.com/qmk/qmk_firmware/blob/master/users/drashna/template.c) in [`users/drashna`](https://github.com/qmk/qmk_firmware/tree/master/users/drashna).
+
+## Custom Features
+
+Since the Userspace feature can support a staggering number of boards, you may have boards that you want to enable certain functionality for, but not for others. And you can actually create "features" that you can enable or disable in your own userspace.  
+
+For instance, if you wanted to have a bunch of macros available, but only on certain boards (to save space), you could "hide" them being a `#ifdef MACROS_ENABLED`, and then enable it per board.  To do this, add this to your rules.mk
+```make
+ifeq ($(strip $(MACROS_ENABLED)), yes)
+    OPT_DEFS += -DMACROS_ENABLED
+endif
 ```
+The `OPT_DEFS` setting causes `MACROS_ENABLED` to be defined for your keyboards (note the `-D` in front of the name), and you could use `#ifdef MACROS_ENABLED` to check the status in your c/h files, and handle that code based on that. 
 
-You can use any option hre that you could use in your keymap's `config.h` file. You can find a list of vales [here](config_options.md).
+Then you add `MACROS_ENABLED = yes` to the `rules.mk` for you keymap to enable this feature and the code in your userspace.
 
-## Example
+And in your `process_record_user` function, you'd do something like this: 
+```c
+bool process_record_user(uint16_t keycode, keyrecord_t *record) {
+  switch (keycode) {
+#ifdef MACROS_ENABLED
+  case MACRO1:
+    if (!record->event.pressed) {
+      SEND_STRING("This is macro 1!");
+    }
+    break;
+  case MACRO2:
+    if (!record->event.pressed) {
+      SEND_STRING("This is macro 2!");
+    }
+    break;
+#endif
+  }
+  return true;
+}
+```

-### Consolidated Macros
+## Consolidated Macros
 
-If you wanted to consolidate macros and other functions into your userspace for all of your keymaps, you can do that.  The issue is that you then cannot call any function defined in your userspace, or it gets complicated.  To better handle this, you can call the functions here and create new functions to use in individual keymaps.
+If you wanted to consolidate macros and other functions into your userspace for all of your keymaps, you can do that.  This builds upon the [Customized Functions](#customized-functions) example above. This lets you maintain a bunch of macros that are shared between the different keyboards, and allow for keyboard specific macros, too. 
 
 First, you'd want to go through all of your `keymap.c` files and replace `process_record_user` with `process_record_keymap` instead.   This way, you can still use keyboard specific codes on those boards, and use your custom "global" keycodes as well.   You'll also want to replace `SAFE_RANGE` with `NEW_SAFE_RANGE` so that you wont have any overlapping keycodes
 
 Then add `#include <name.h>` to all of your keymap.c files.  This allows you to use these new keycodes without having to redefine them in each keymap.
 
 Once you've done that, you'll want to set the keycode definitions that you need to the `<name>.h`  file. For instance:
-```
-#ifndef USERSPACE
-#define USERSPACE
+```c
+#pragma once
 
 #include "quantum.h"
+#include "action.h"
+#include "version.h"
 
 // Define all of
 enum custom_keycodes {
   KC_MAKE = SAFE_RANGE,
   NEW_SAFE_RANGE  //use "NEW_SAFE_RANGE" for keymap specific codes
 };
-
-#endif
 ```
 
 Now you want to create the `<name>.c` file, and add this content to it:
 
-```
+```c
 #include "<name>.h"
-#include "quantum.h"
-#include "action.h"
-#include "version.h"
 
 __attribute__ ((weak))

And this will work with any keyboard and any keymap as it will output the current boards info, so that you don't have to type this out every time.
 
 Additionally, this should flash the newly compiled firmware automatically, using the correct utility, based on the bootloader settings (or default to just generating the HEX file). However, it should be noted that this may not work on all systems. AVRDUDE doesn't work on WSL, namely (and will dump the HEX in the ".build" folder instead).

 ### Keyboard Matrix Configuration
 
 The next section of the `config.h` file deals with your keyboard's matrix. The first thing you should set is the matrix's size. This is usually, but not always, the same number of rows and columns as the physical key arrangement.
 
-```
+```c
 #define MATRIX_ROWS 2
 #define MATRIX_COLS 3
 ```
 
 Once you've defined the size of your matrix you need to define which pins on your MCU are connected to rows and columns. To do so simply specify the names of those pins:

+
+### Configuration
+
+The following defines can be used to configure the I2C master driver.
+
+|Variable          |Description                                        |Default|
+|------------------|---------------------------------------------------|-------|
+|`#F_SCL`          |Clock frequency in Hz                              |400KHz |
+|`#Prescaler`      |Divides master clock to aid in I2C clock selection |1      |
+
+AVRs usually have set GPIO which turn into I2C pins, therefore no further configuration is required.
+
+## ARM
+
+For ARM the Chibios I2C HAL driver is under the hood.
+This section assumes an STM32 MCU.
+
+### Configuration
+
+The configuration for ARM MCUs can be quite complex as often there are multiple I2C drivers which can be assigned to a variety of ports.
+
+Firstly the `mcuconf.h` file must be setup to enable the necessary hardware drivers.
+
+|Variable                      |Description                                                                        |Default|
+|------------------------------|------------------------------------------------------------------------------------|-------|
+|`#STM32_I2C_USE_XXX`          |Enable/Disable the hardware driver XXX (each driver should be explicitly listed)    |FALSE  |
+|`#STM32_I2C_BUSY_TIMEOUT`     |Time in ms until the I2C command is aborted if no response is received              |50     |
+|`#STM32_I2C_XXX_IRQ_PRIORITY` |Interrupt priority for hardware driver XXX (THIS IS AN EXPERT SETTING)              |10     |
+|`#STM32_I2C_USE_DMA`          |Enable/Disable the ability of the MCU to offload the data transfer to the DMA unit  |TRUE   |
+|`#STM32_I2C_XXX_DMA_PRIORITY` |Priority of DMA unit for hardware driver XXX (THIS IS AN EXPERT SETTING)            |1      |
+
+Secondly, in the `halconf.h` file, `#define HAL_USE_I2C` must be set to `TRUE`. This allows ChibiOS to load its I2C driver.
+
+Lastly, we need to assign the correct GPIO pins depending on the I2C hardware driver we want to use.
+
+By default the I2C1 hardware driver is assumed to be used. If another hardware driver is used,  `#define I2C_DRIVER I2CDX` should be added to the `config.h` file with X being the number of hardware driver used. For example is I2C3 is enabled, the `config.h` file should contain `#define I2C_DRIVER I2CD3`. This aligns the QMK I2C driver with the Chibios I2C driver.
+
+STM32 MCUs allows a variety of pins to be configured as I2C pins depending on the hardware driver used. By default B6 and B7 are set to I2C.
+
+This can be changed by declaring the `i2c_init` function which intentionally has a weak attribute. Please consult the datasheet of your MCU for the available GPIO configurations. The following is an example initialization function:
+
+```C
+void i2c_init(void)
+{
+  setPinInput(B6); // Try releasing special pins for a short time
+  setPinInput(B7);
+  chThdSleepMilliseconds(10); // Wait for the release to happen
+
+  palSetPadMode(GPIOB, 6, PAL_MODE_ALTERNATE(4) | PAL_STM32_OTYPE_OPENDRAIN | PAL_STM32_PUPDR_PULLUP); // Set B6 to I2C function
+  palSetPadMode(GPIOB, 7, PAL_MODE_ALTERNATE(4) | PAL_STM32_OTYPE_OPENDRAIN | PAL_STM32_PUPDR_PULLUP); // Set B7 to I2C function
+}
+```

+# GPIO Control
+
+QMK has a GPIO control abstraction layer which is micro-controller agnostic. This is done to allow easy access to pin control across different platforms.
+
+## Functions
+
+The following functions can provide basic control of GPIOs and are found in `quantum/quantum.h`.
+
+|Function              |Description                                                       |
+|----------------------|------------------------------------------------------------------|
+|`setPinInput(pin)`    |Set pin as input with high impedance (High-Z)                     |
+|`setPinInputHigh(pin)`|Set pin as input with build in pull-up                            |
+|`setPinInputLow(pin)` |Set pin as input with build in pull-down (Supported only on STM32)|
+|`setPinOutput(pin)`   |Set pin as output                                                 |
+|`writePinHigh(pin)`   |Set pin level as high, assuming it is an output                   |
+|`writePinLow(pin)`    |Set pin level as low, assuming it is an output                    |
+|`writePin(pin, level)`|Set pin level, assuming it is an output                           |
+|`readPin(pin)`        |Returns the level of the pin                                      |
+
+## Advance settings
+
+Each micro-controller can have multiple advance settings regarding its GPIO. This abstraction layer does not limit the use of architecture specific functions. Advance users should consult the datasheet of there desired device and include any needed libraries. For AVR the standard avr/io.h library is used and for STM32 the Chibios [PAL library](http://chibios.sourceforge.net/docs3/hal/group___p_a_l.html) is used.

 Unfortunately, these keycodes cannot be used in Mod-Taps or Layer-Taps, since any modifiers specified in the keycode are ignored.
 
+Additionally, you may run into issues when using Remote Desktop Connection on Windows. Because these codes send shift very fast, Remote Desktop may miss the codes.

+To fix this, open Remote Desktop Connection, click on "Show Options", open the the "Local Resources" tab. In the keyboard section, change the drop down to "On this Computer". This will fix the issue, and allow the characters to work correctly.

+# Best Practices
+
+## Or, "How I Learned to Stop Worrying and Love Git."
+
+This document aims to instruct novices in the best ways to have a smooth experience in contributing to QMK. We will walk through the process of contributing to QMK, detailing some ways to make this task easier, and then later we'll break some things in order to teach you how to fix them.
+
+This document assumes a few things:
+
+1. You have a GitHub account, and have [forked the qmk_firmware repository](getting_started_github.md) to your account.
+2. You've [set up your build environment](newbs_getting_started.md?id=environment-setup).
+
+
+## Your fork's master: Update Often, Commit Never
+
+It is highly recommended for QMK development, regardless of what is being done or where, to keep your `master` branch updated, but ***never*** commit to it. Instead, do all your changes in a development branch and issue pull requests from your branches when you're developing.
+
+To reduce the chances of merge conflicts &mdash; instances where two or more users have edited the same part of a file concurrently &mdash; keep your `master` branch relatively up-to-date, and start any new developments by creating a new branch.
+
+### Updating your master branch
+
+To keep your `master` branch updated, it is recommended to add the QMK Firmware repository ("repo") as a remote repository in git. To do this, open your Git command line interface and enter:
+
+```
+git remote add upstream https://github.com/qmk/qmk_firmware.git
+```
+
+To verify that the repository has been added, run `git remote -v`, which should return the following:
+
+```
+$ git remote -v
+origin  https://github.com/<your_username>/qmk_firmware.git (fetch)
+origin  https://github.com/<your_username>/qmk_firmware.git (push)
+upstream        https://github.com/qmk/qmk_firmware.git (fetch)
+upstream        https://github.com/qmk/qmk_firmware.git (push)
+```
+
+Now that this is done, you can check for updates to the repo by running `git fetch upstream`. This retrieves the branches and tags &mdash; collectively referred to as "refs" &mdash; from the QMK repo, which now has the nickname `upstream`. We can now compare the data on our fork `origin` to that held by QMK.
+
+To update your fork's master, run the following, hitting the Enter key after each line:
+
+```
+git checkout master
+git fetch upstream
+git pull upstream master
+git push origin master
+```
+
+This switches you to your `master` branch, retrieves the refs from the QMK repo, downloads the current QMK `master` branch to your computer, and then uploads it to your fork.
+
+### Making Changes
+
+To make changes, create a new branch by entering:
+
+```
+git checkout -b dev_branch
+git push --set-upstream origin dev_branch
+```
+
+This creates a new branch named `dev_branch`, checks it out, and then saves the new branch to your fork. The `--set-upstream` argument tells git to use your fork and the `dev_branch` branch every time you use `git push` or `git pull` from this branch. It only needs to be used on the first push; after that, you can safely use `git push` or `git pull`, without the rest of the arguments.
+
+!> With `git push`, you can use `-u` in place of `--set-upstream` &mdash; `-u` is an alias for `--set-upstream`.
+
+You can name your branch nearly anything you want, though it is recommended to name it something related to the changes you are going to make.
+
+By default `git checkout -b` will base your new branch on the branch that is checked out. You can base your new branch on an existing branch that is not checked out by adding the name of the existing branch to the command:
+
+```
+git checkout -b dev_branch master
+```
+
+Now that you have a development branch, open your text editor and make whatever changes you need to make. It is recommended to make many small commits to your branch; that way, any change that causes issues can be more easily traced and undone if needed. To make your changes, edit and save any files that need to be updated, add them to Git's *staging area*, and then commit them to your branch:
+
+```
+git add path/to/updated_file
+git commit -m "My commit message."
+```
+
+`git add` adds files that have been changed to Git's *staging area*, which is Git's "loading zone." This contains the changes that are going to be *committed* by `git commit`, which saves the changes to the repo. Use descriptive commit messages so you can know what was changed at a glance.
+
+!> If you've changed a lot of files, but all the files are part of the same change, you can use `git add .` to add all the changed files that are in your current directory, rather than having to add each file individually.
+
+### Publishing Your Changes
+
+The last step is to push your changes to your fork. To do this, enter `git push`. Git now publishes the current state of `dev_branch` to your fork.
+
+
+## Resolving Merge Conflicts
+
+Sometimes when your work in a branch takes a long time to complete, changes that have been made by others conflict with changes you have made to your branch when you open a pull request. This is called a *merge conflict*, and is what happens when multiple people edit the same parts of the same files.
+
+### Rebasing Your Changes
+
+A *rebase* is Git's way of taking changes that were applied at one point, reversing them, and then applying the same changes to another point. In the case of a merge conflict, you can rebase your branch to grab the changes that were made between when you created your branch and the present time.
+
+To start, run the following:
+
+```
+git fetch upstream
+git rev-list --left-right --count HEAD...upstream/master
+```
+
+The `git rev-list` command entered here returns the number of commits that differ between the current branch and QMK's master branch. We run `git fetch` first to make sure we have the refs that represent the current state of the upstream repo. The output of the `git rev-list` command entered returns two numbers:
+
+```
+$ git rev-list --left-right --count HEAD...upstream/master
+7       35
+```
+
+The first number represents the number of commits on the current branch since it was created, and the second number is the number of commits made to `upstream/master` since the current branch was created, and thus, the changes that are not recorded in the current branch.
+
+Now that the current states of both the current branch and the upstream repo are known, we can start a rebase operation:
+
+```
+git rebase upstream/master
+```
+
+This tells Git to undo the commits on the current branch, and then reapply them against QMK's master branch.
+
+```
+$ git rebase upstream/master
+First, rewinding head to replay your work on top of it...
+Applying: Commit #1
+Using index info to reconstruct a base tree...
+M       conflicting_file_1.txt
+Falling back to patching base and 3-way merge...
+Auto-merging conflicting_file_1.txt
+CONFLICT (content): Merge conflict in conflicting_file_1.txt
+error: Failed to merge in the changes.
+hint: Use 'git am --show-current-patch' to see the failed patch
+Patch failed at 0001 Commit #1
+
+Resolve all conflicts manually, mark them as resolved with
+"git add/rm <conflicted_files>", then run "git rebase --continue".
+You can instead skip this commit: run "git rebase --skip".
+To abort and get back to the state before "git rebase", run "git rebase --abort".
+```
+
+This tells us that we have a merge conflict, and gives the name of the file with the conflict. Open the conflicting file in your text editor, and somewhere in the file, you'll find something like this:
+
+```
+<<<<<<< HEAD
+<p>For help with any issues, email us at support@webhost.us.</p>
+=======
+<p>Need help? Email support@webhost.us.</p>
+>>>>>>> Commit #1
+```
+
+The line `<<<<<<< HEAD` marks the beginning of a merge conflict, and the `>>>>>>> Commit #1` line marks the end, with the conflicting sections separated by `=======`. The part on the `HEAD` side is from the QMK master version of the file, and the part marked with the commit message is from the current branch and commit.
+
+Because Git tracks *changes to files* rather than the contents of the files directly, if Git can't find the text that was in the file previous to the commit that was made, it won't know how to edit the file. Re-editing the file will solve the conflict. Make your changes, and then save the file.
+
+```
+<p>Need help? Email support@webhost.us.</p>
+```
+
+Now run:
+
+```
+git add conflicting_file_1.txt
+git rebase --continue
+```
+
+Git logs the changes to the conflicting file, and continues applying the commits from our branch until it reaches the end.

This means that any time that you use a keycode to change the layer, this will be checked.  So you could use `LT(layer, kc)` to change the layer and it will trigger the same layer check. 
+This function is useful if you want to create specific keys that have this functionality, but other layer keycodes won't do this.
 
-The caveat to this method is that you cannot access the `z` layer without having `x` and `y` layers on, since if you try to activate just layer `z`, it will run this code and turn off layer `z` before you could use it.

+      }
+      return false;
+      break;

+      }
+      return false;
+      break;
+    }
+  return true;
+}
+```

+# Supporting Your Keyboard in QMK Configurator
+
+This page covers how to properly support keyboards in the [QMK Configurator](https://config.qmk.fm/).
+
+
+## How the Configurator Understands Keyboards
+
+To understand how the Configurator understands keyboards, first one must understand layout macros. For this exercise, we're going to imagine a 17-key numpad PCB, which we're going to call `numpad`.
+
+```
+┌───┬───┬───┬───┐
+│NLk│ / │ * │ - │
+├───┼───┼───┼───┤
+│7  │8  │9  │ + │
+├───┼───┼───┤   │
+│4  │5  │6  │   │
+├───┼───┼───┼───┤
+│1  │2  │3  │Ent│
+├───┴───┼───┤   │
+│0      │ . │   │
+└───────┴───┴───┘
+```
+
+?> For more on layout macros, see [Understanding QMK: Matrix Scanning](understanding_qmk.md?id=matrix-scanning) and [Understanding QMK: Matrix to Physical Layout Map](understanding_qmk.md?id=matrix-to-physical-layout-map).
+
+The Configurator's API reads the keyboard's `.h` file from `qmk_firmware/keyboards/<keyboard>/<keyboard>.h`. For our numpad, this file would be `qmk_firmware/keyboards/numpad/numpad.h`:
+
+```c
+#pragma once
+
+#define LAYOUT( \
+    k00, k01, k02, k03, \
+    k10, k11, k12, k13, \
+    k20, k21, k22,      \
+    k30, k31, k32, k33, \
+    k40,      k42       \
+  ) { \
+    { k00, k01,   k02, k03   }, \
+    { k10, k11,   k12, k13   }, \
+    { k20, k21,   k22, KC_NO }, \
+    { k30, k31,   k32, k33   }, \
+    { k40, KC_NO, k42, KC_NO }  \
+}
+```
+
+QMK uses `KC_NO` to designate places in the switch matrix where there is no switch. Sometimes, `XXX`, `___` or `____` are used as shorthand to make this section easier to read if it needs to be debugged. This is usually defined near the beginning of the `.h` file:
+
+```c
+#pragma once
+
+#define XXX KC_NO
+
+#define LAYOUT( \
+    k00, k01, k02, k03, \
+    k10, k11, k12, k13, \
+    k20, k21, k22,      \
+    k30, k31, k32, k33, \
+    k40,      k42       \
+  ) { \
+    { k00, k01, k02, k03 }, \
+    { k10, k11, k12, k13 }, \
+    { k20, k21, k22, XXX }, \
+    { k30, k31, k32, k33 }, \
+    { k40, XXX, k42, XXX }  \
+}
+```
+
+!> This usage differs from that of keymap macros, which almost always use `XXXXXXX` (seven capital X's) for `KC_NO` and `_______` (seven underscores) for `KC_TRNS`.
+
+!> To prevent user confusion, using `KC_NO` is preferred.
+
+The layout macro tells the Configurator that our keyboard has 17 keys, arranged in five rows of four columns each. Our switch positions are named `k<row><column>`, counting from 0. The names themselves actually don't matter, as long as they match between the top section, which receives the keycodes from the keymap, and the bottom half which designates where each key is in the matrix.
+
+To display our keyboard in a way that resembles the physical keyboard, we need to build a JSON file that tells the Configurator how to tie the physical locations and sizes of our keys to our switch matrix.
+
+## Building the JSON file
+
+To build the JSON file, the easiest way is to build the layout in [Keyboard Layout Editor](http://www.keyboard-layout-editor.com/) ("KLE"), from which we'll feed the Raw Data into a QMK tool that converts this data into a JSON the Configurator will read and use. Since KLE opens by default with a numpad layout, we're just going to remove the Getting Started instructions, and use what's left.
+
+Once the layout is as desired, move to the Raw Data tab in KLE, and copy the contents:
+
+```
+["Num Lock","/","*","-"],
+["7\nHome","8\n↑","9\nPgUp",{h:2},"+"],
+["4\n←","5","6\n→"],
+["1\nEnd","2\n↓","3\nPgDn",{h:2},"Enter"],
+[{w:2},"0\nIns",".\nDel"]
+```
+
+To convert this data into our JSON, go to the [QMK KLE-JSON Converter](https://qmk.fm/converter/), paste the Raw Data into the Input field, and click the Convert button. After a moment, our JSON data will appear in the Output field. Copy the contents to a new text document, and name the document `info.json`, saving it in the same folder that contains `numpad.h`.
+
+Use the `keyboard_name` object to set the name of the keyboard. The `bootloader` object is deprecated, so it can be deleted. For instruction purposes, we will put each key's object on its own line. This is only to make the file more human-readable, and does not affect the Configurator's functionality.

+    "keyboard_name": "Numpad",
+    "url": "",
+    "maintainer": "qmk",
+    "tags": {

+                {"label":"8", "x":1, "y":1},
+                {"label":"9", "x":2, "y":1},
+                {"label":"+", "x":3, "y":1, "h":2},
+                {"label":"4", "x":0, "y":2},

+                {"label":"6", "x":2, "y":2},
+                {"label":"1", "x":0, "y":3},
+                {"label":"2", "x":1, "y":3},

+            ]
+        }
+    }
+}
+```
+
+The `layouts` object contains the data that represents the physical layout of the keyboard. It has an object `LAYOUT`, which needs to match the name of our layout macro from `numpad.h`. The `LAYOUT` object itself has an object named `layout`, which contains one JSON object for each physical key on our keyboard, formatted as follows:
+
+```
+  ┌ The name of the key. Not displayed in the Configurator.
+  │                   ┌ The key's X-axis location, in key units from the
+  │                   │ keyboard's left edge.
+  │                   │      ┌ The key's Y-axis location, in key units from
+  │                   │      │ the keyboard's top (rear-facing) edge.
+  ↓                   ↓      ↓
+{"label":"Num Lock", "x":0, "y":0},
+```
+
+Some objects will also have `"w"` and `"h"` keys, which represent a key's width and height, respectively.
+
+?> For more on the `info.json` files, see [QMK Keyboard Guidelines: Keyboard Metadata](hardware_keyboard_guidelines.md?id=keyboard-metadata)
+
+
+## How the Configurator Programs Keys
+
+The Configurator's API uses the layout macro and the JSON file we've given it to create a visual representation of the keyboard that has each visual object tied to a specific key, in sequence:
+
+key in layout macro | JSON object used
+:---: | :----
+k00   | {"label":"Num Lock", "x":0, "y":0}
+k01   | {"label":"/", "x":1, "y":0}
+k02   | {"label":"*", "x":2, "y":0}
+k03   | {"label":"-", "x":3, "y":0}
+k10   | {"label":"7", "x":0, "y":1}
+k11   | {"label":"8", "x":1, "y":1}
+k12   | {"label":"9", "x":2, "y":1}
+k13   | {"label":"+", "x":3, "y":1, "h":2}
+k20   | {"label":"4", "x":0, "y":2}
+k21   | {"label":"5", "x":1, "y":2}
+k22   | {"label":"6", "x":2, "y":2}
+k30   | {"label":"1", "x":0, "y":3}
+k31   | {"label":"2", "x":1, "y":3}
+k32   | {"label":"3", "x":2, "y":3}
+k33   | {"label":"Enter", "x":3, "y":3, "h":2}
+k40   | {"label":"0", "x":0, "y":4, "w":2}
+k42   | {"label":".", "x":2, "y":4}
+
+When a user selects the top-left key in the Configurator, and assigns Num Lock to it, the Configurator builds a keymap file with `KC_NLCK` as the first key, and so on as the keymap is built. The `label` keys are not used; they are only for the user's reference in identifying specific keys when debugging the `info.json` file.
+
+
+## Issues and Hazards
+
+Currently, the Configurator does not support key rotation or non-rectangular key shapes like ISO Enter. Additionally, keys that are vertically-offset from their "row" &mdash; the arrow keys on 1800-layouts like the [TKC1800](https://github.com/qmk/qmk_firmware/tree/4ac48a61a66206beaf2fdd5f2939d8bbedd0004c/keyboards/tkc1800/) being a prominent example &mdash; confuse the KLE-to-JSON Converter, if not adjusted for by the contributor of the `info.json` file.
+
+### Workarounds
+
+#### Non-rectangular keys
+
+For ISO Enter keys, QMK custom is to display it as a rectangular key, 1.25u wide and 2u high, aligned so its right edge is aligned with the right edge of the alphanumeric key block.

+*A 60% keyboard in standard ISO layout, as rendered by QMK Configurator.*
+
+#### Vertically-offset keys
+
+For vertically-offset keys, place them in KLE as if they were not offset, then edit the Y-values as needed in the converted JSON file

+# Support
+
+If you need help with something, the best place to get quick support is going to be on our [Discord Server](https://discord.gg/Uq7gcHh).  There is usually somebody online, and there are a bunch of very helpful people there.
+
+Don't forget to read our [Code of Conduct](https://qmk.fm/coc/).
+
+## Help! I don't know where to start! 
+
+If this is the case, then you should start with our [Newbs Guide](https://docs.qmk.fm/#/newbs). There is a lot of great info there, and that should cover everything you need to get started.
+
+If that's an issue, hop onto the [QMK Configurator](https://config.qmk.fm), as that will handle a majority of what you need there. 
+
+## Help! I'm having issues flashing!
+
+First, head to the [Compiling/Flashing FAQ Page](https://docs.qmk.fm/#/faq_build). There is a good deal of info there, and you'll find a bunch of solutions to common issues there. 
+
+## Help, I have an issue that isn't covered by the links above
+
+Okay, that's fine. Then please check the [open issues in our GitHub](https://github.com/qmk/qmk_firmware/issues) to see if somebody is experiencing the same thing (make sure it's not just similar, but actually the same).  
+
+If you can't find anything, then please open a [new issue](https://github.com/qmk/qmk_firmware/issues/new)!
+
+## What if I found a bug? 
+
+Then please open an [issue](https://github.com/qmk/qmk_firmware/issues/new), and if you know how to fix it, open up a Pull Request on GitHub with the fix.
+
+## But `git` and `GitHub` are intimidating! 
+
+Don't worry, we have some pretty nice [Guidelines](https://docs.qmk.fm/#/newbs_best_practices) on how to start using `git` and GitHub to make things easier to develop. 
+
+Additionally, you can find additional `git` and GitHub related links [here](https://docs.qmk.fm/#/newbs_learn_more_resources).
+
+## I have a Keyboard that I want to add support for
+
+Awesome! Open up a Pull Request for it. We'll review the code, and merge it!  
+
+### What if I want to do brand it with `QMK`? 
+
+That's amazing! We would love to assist you with that! 
+
+In fact, we have a [whole page](https://qmk.fm/powered/) dedicated to adding QMK Branding to your page and keyboard. This covers pretty much everything you need (knowledge and images) to officially support QMK.
+
+If you have any questions about this, open an issue or head to [Discord](https://discord.gg/Uq7gcHh).

+
+## 什麼是QMK固件？
+
+QMK是一個由社群維護的開源鍵盤韌體，其中包含了QMK Toolbox、qmk.fm和其它文件。QMK韌體是以[tmk\_keyboard](http://github.com/tmk/tmk_keyboard)為基礎，讓一些有用的功能在Atmel AVR控制器實現，使用於[OLKB](https://olkb.com)、[ergodox EZ](http://www.ergodox-ez.com)，和[Clueboard](http://clueboard.co/)的產品中。它也被移植到使用ChibiOS的ARM晶片上。你也可以用它來讓你徒手佈線，或是客製的鍵盤PCB發揮功能。
+
+## 如何得到QMK
+
+如果你打算貢獻鍵盤佈局，鍵盤或功能QMK，最容易做的事情是[叉通過Github上爬行](https://github.com/qmk/qmk_firmware#fork-destination-box)，和克隆你爬在本地進行更改，推動他們，然後打開從你的叉子[拉請求](https://github.com/qmk/qmk_firmware/pulls)。
+
+否則，您可以直接下載([拉鍊](https://github.com/qmk/qmk_firmware/zipball/master) [焦油](https://github.com/qmk/qmk_firmware/tarball/master))，或者通過GIT中克隆它(`git@github.com:qmk/qmk_firmware.git`)或HTTP(`https://github.com/qmk/qmk_firmware.git`)。
+
+## 如何編譯
+
+你可以編譯之前，你需要[安裝環境](getting_started_build_tools.md)用於AVR或/和ARM開發。一旦完成，你會使用`make`命令建立一個鍵盤並用以下符號鍵盤佈局
+
+    make planck/rev4:default
+
+這將建立`rev4` `planck`的修訂與`default`鍵盤映射。並非所有鍵盤有一個修訂版(也稱為子項目或文件夾)，在這種情況下，它可以被省略：
+
+    make preonic:default
+
+## 如何赶近
+
+QMK有很多[特點](features.md)探索和很好的協議[參考文獻](http://docs.qmk.fm)挖通的。大部分功能通過修改[鍵盤映射(keymap.md)，並改變[鍵碼](keycodes.md)冤大頭。
