+# Default Keymap
+
+This default keymap follows many of the norms seen in non-programmable keyboards
+  to ease initial use of the Hillside keyboard.
+It is a starting point for you to tweak over time to better suit _your_ preferences.
+You can easily customize it with the
+  [QMK configurator](https://config.qmk.fm/#/hillside/0_1/LAYOUT)
+  or with the [via firmware](https://caniusevia.com).
+
+Some of its key features are:
+- A mostly standard base layer with letters, some symbols, shift, modifier and delete keys
+  in the expected places for non-programmable keyboards.
+- QWERTY, Colemak-DH and Dvorak options for the letter and symbol layout.
+- Comfortable modifier and function or symbol combinations on the non-base layers
+  using modifiers on the home row of the navigation/edit, symbol/function and number-pad layers.
+- Word navigation and cut/copy/paste keys on the navigation layer.
+- A slightly optimized number pad with the more frequently used numbers on the home row.
+
+We've deliberately omitted some features:
+- Combos: because the online configuration tools do not handle them
+  and because they would add to the initial learning curve,
+  as helpful to a keymap as a light sprinkling of combos can be.
+- Multi-function mod-tap keys, auto shift capitalization and auto-exit modes such as CAPWORD or NUMWORD:
+  as they may be too large a step for someone new to programmable keyboards.
+
+## Base Layer
+
+```
+| TAB   |  Q  |  W  |  E  |  R  |  T  |---------------------------|  Y  |  U  |  I  |  O  |  P  | BKSPC |
+| CTRL  |  A  |  S  |  D  |  F  |  G  |---------------------------|  H  |  J  |  K  |  L  |  ;  |   '   |
+| SHIFT |  Z  |  X  |  C  |  V  |  B  |  ~  |---------------| ESC |  N  |  M  |  ,  |  .  |  /  | SHIFT |
+--------------|ENTER|-----| GUI | ALT | Num | Nav |---| Sym |SPACE| ALT | GUI |-----| APP |--------------
+```
+
+The base layer can be either of QWERTY, Colemak-DH or Dvorak,
+  with identical non-alpha and non-symbol keys.
+QWERTY is the default.
+
+A standard keyboard layout is used for:
+
+- Tab, backspace and shift keys in the outer columns.
+- Alt/option and GUI/command keys on both thumbs, with the location swappable for windows or mac.
+- A space key on the right thumb.
+
+The differences from a standard layout are:
+
+- There are three additional "shift" keys
+  to access the navigation/editing, symbol/function, and number layers.
+- Enter is on the left thumb or ring finger.
+  This location allowed preserving the more common right-hand keys.
+  Feel free to swap it with the quote key or have it share the right shift key
+    as a mod-tap key.
+- Control is in the caps lock spot.
+- Esc and `~ are above the thumbs.
+- The rarer AltGr key is in a layer.
+
+<details>
+<summary>Details of Dvorak and Colemak-DH</summary>
+In the Dvorak layout, the outer home row key is the "/?" symbols
+  so that the same 12 symbols are taken care of on the base layer.
+
+```
+Dvorak
+| TAB   |  '  |  ,  |  .  |  P  |  Y  |---------------------------|  F  |  G  |  C  |  R  |  L  | BKSPC |
+| CTRL  |  A  |  O  |  E  |  U  |  I  |---------------------------|  D  |  H  |  T  |  N  |  S  |  /    |
+| SHIFT |  ;  |  Q  |  J  |  K  |  X  |  ~  |---------------| ESC |  B  |  M  |  W  |  V  |  Z  | SHIFT |
+--------------|ENTER|-----| GUI | ALT | Num | Nav |---| Sym |SPACE| ALT | GUI |-----| APP |--------------
+
+Colemak-DH
+| TAB   |  Q  |  W  |  F  |  P  |  B  |---------------------------|  J  |  L  |  U  |  Y  |  ;  | BKSPC |
+| CTRL  |  A  |  R  |  S  |  T  |  G  |---------------------------|  M  |  N  |  E  |  I  |  O  |   '   |
+| SHIFT |  Z  |  X  |  C  |  D  |  V  |  ~  |---------------| ESC |  K  |  H  |  ,  |  .  |  /  | SHIFT |
+--------------|ENTER|-----| GUI | ALT | Num | Nav |---| Sym |SPACE| ALT | GUI |-----| APP |--------------
+```
+</details>
+
+## Navigation, Editing and Media Layer
+
+```
+| CAPS  | INS |     |     |     |VOL+ |---------------------------|PG_UP|HOME |     |  END|     | DEL   |
+| CTRL  | GUI | ALT |CTRL |SHIFT|VOL- |---------------------------|PG_DN|LEFT | UP  |RIGHT|     | CTRL  |
+| SHIFT |UNDO | CUT |COPY |PASTE|REDO |MUTE |---------------| ESC |     |WORDL|DOWN |WORDR|RALT | SHIFT |
+--------------|ENTER|-----| GUI | ALT | Num | *** |---| Adj |BSPC | ALT | GUI |-----| APP |--------------
+```
+Holding down the Nav key accesses a navigation and editing layer:
+
+- Navigation arrows are on and below the right home row in a cross pattern.
+  This feels more natural for a column stagger keyboard than an inverted T.
+  The keys below that move left or right by a word.
+  Home, end, and page up/down are beside them.
+- Modifiers in the left home row make it easier to use the arrows
+  to select text with the shift key or move between desktops or tabs.
+- Editing keys appear on the lower left.
+  The edit keys, modifiers and arrows make it easy to move text around without leaving the layer.
+- Delete is in the upper right, and a backspace key is on the thumb.
+- The base layer modifiers and escape are in the same spots as on the base layer,
+  and a right-hand control key is added.
+- Media volume and play keys are on the left, accessible with one hand.
+- AltGr and caps lock fill out the layer.
+- A few keys do nothing and are available for more user-specific needs.
+
+## Symbol and Function Layer
+
+```
+| F12   |  !  |  @  |  #  |  $  |  %  |---------------------------|  ^  |  &  |  *  |  (  |  )  | BSPC  |
+| CTRL  | F1  | F2  | F3  | F4  | F5  |---------------------------|  |  |SHIFT|CTRL | ALT | GUI | CTRL  |
+| SHIFT | F6  | F7  | F8  | F9  | F10 | F11 |---------------| ESC |  \  |  [  |  ]  |  {  |  }  | SHIFT |
+--------------|ENTER|-----| GUI | ALT | Num | Adj |---| *** |SPACE| ALT | GUI |-----| APP |--------------
+```
+Holding down the Sym key accesses a layer of symbol and function keys:
+
+- The symbols usually found on the number keys are in the top row.
+  If desired, you can use these positions for other things,
+  as the symbols are also accessible from the number pad layer with the shift key.
+- The remaining symbols appear on the right.
+- The function keys are on the left, beginning with two rows of five.
+- A row of modifiers in the home row allows the comfortable creation of any modifier and function key combination.  
+- The base layer modifier and escape keys are still available, as is a right-hand control key.
+
+##  Number Pad and Algebraic Layer
+```
+|       |  -  |  +  |  =  |  /  |  *  |---------------------------|  .  |  7  |  8  |  9  |     | BSPC  |
+| CTRL  | GUI | ALT |CTRL |SHIFT|     |---------------------------|  0  |  1  |  2  |  3  |  _  | CTRL  |
+| SHIFT |     |     |     |     |     |     |---------------| ESC |  ,  |  4  |  5  |  6  |     | SHIFT |
+--------------|ENTER|-----| GUI | ALT | *** |     |---|     |BSPC | ALT | GUI |-----| APP |--------------
+```
+Holding down the Num key accesses a number pad and arithmetic symbols:
+
+- The number pad has the lowest numbers swapped into the home row as these are the most commonly used.
+- A row of modifiers in the home row allows the comfortable creation of any modifier and number combination.
+- Symbols commonly used with numbers fill out the layer
+   and can be combined with the home row mods or the existing base layer modifiers on the right hand.
+- Several keys remain unused and await more user-specific needs.
+
+
+## Adjust Layer
+```
+|       |QWERT|DVORK|COLMK|AG_SWAP|AG_NORM|-----------------------|     |     |     |     |     |       |
+|       |     |     |     |     |     |---------------------------|MOD+ |BRI+ |HUE+ |SAT+ |     |       |
+| RESET |     |     |     |     |     |     |--------------|RGBTOG|MOD- |BRI- |HUE- |SAT- |     |       |
+--------------|     |-----|     |     |     | *** |---| *** |     |     |     |-----|     |--------------
+```
+Simultaneously holding down the Nav and Sym keys enables keys to adjust various keyboard settings:
+
+- The base layer can be set to QWERTY, Colemak-DH or Dvorak,
+  but the keyboard reverts to QWERTY each time it is plugged in.
+- Alt/option and GUI/command can be swapped for mac users or restored to the windows norm.
+  This setting persists over power loss.
+- The backlight LEDs can be enabled, disabled, and controlled.
+  These settings also persist over power loss.
+
+
+## Make it Yours
+
+If you are coming from a traditional keyboard,
+  with a row-staggered layout and a large set of physical keys,
+  learning to use a column staggered (ergo) and layer-based keyboard,
+  which uses layers instead of finger reaches to access numbers, symbols and functions,
+  will be an adjustment for your muscle memory and your mental keyboard map.
+This default layout tries to simplify that adjustment by keeping things    in the expected spots when possible.
+
+Yet this layout is only a decent compromise and is not optimal for each user.
+
+The online configurator makes it easy to tweak this layout to your needs.
+You can add additional layers or completely switch around what these do.
+
+Some changes you might consider making:
+- Put some of your most-used key combinations on the unused keys on the navigation layer.
+- If you are on a mac, switch the editing and word navigation keys from ctrl-x to cmd-x.
+- Change the shift keys to one-shot shift keys,
+  where pressing and releasing them shifts the next key pressed.
+  That is much easier on your hands than holding them down.
+  Yet, they can still be held as usual if desired.
+- Instead of holding down the thumb key to keep the symbol layer active,
+  you could use a one-shot layer key.
+  One-shot modifiers are likely less stress on your hands and may even be faster.
+  You would still be able to hold it down instead.
+- Instead of holding down the key for the number pad layer,
+  you could make it a layer toggle, like caps lock is a capitalization toggle key.
+
+Here are some other keymaps for inspiration and ideas:
+- The [Ferris default](https://github.com/qmk/qmk_firmware/tree/master/keyboards/ferris/keymaps/default) uses more advanced features as it has far fewer keys to work with.
+- The [Miryoku](https://github.com/manna-harbour/miryoku/tree/master/docs/reference) keymap ensures that all modifiers are comfortably available with each character key.
+- The [Kyria default](https://github.com/qmk/qmk_firmware/tree/master/keyboards/splitkb/kyria/keymaps/default) has different keymap choices and a couple more keys.
+
+A good metaphor is to think of your keymap as a bonsai tree that you tweak slightly over time
+  in response to ideas of how it might serve you better.
+
+
+## Why no keymap.c
+
+Via and the online configurator provide straightforward visual ways to work with a simple layout,
+  and both use a .json keymap format.
+So this default ```keymap.json``` was created with the online configurator
+  and formatted for easier reading and editing.
+
+If you wish, you can edit the ```keymap.json``` directly in a text editor, optionally use the below ```json2hill.py``` to restore the spacing, and then compile and flash it.
+
+Or, you can use the graphical configurator to edit the keymap. To do that:
+
+- Open the [QMK configurator](https://config.qmk.fm/#/handwired/hillside/LAYOUT)
+- Using the green up arrow button, load the keymap from ```qmk_firmware/keyboards/handwired/hillside/keymaps/default/keymap.json```
+- Make the changes you wish to the layout
+- Save the keymap using the green down arrow button.
+- Copy those changes back into your QMK repository and reformat for easy reading using the format script:
+```
+./keyboards/handwired/hillside/keymaps/json2hill.py --input <Your download directory>/default.json > ./keyboards/handwired/hillside/keymaps/default/keymap.json
+```
+   You may need to make that script executable with ```chmod +x```. After your keymap is safely copied and formated, you may want to remove the keymap from your download directory so later downloads will automatically receive the same file name.
+
+After either method of editing, compile and flash the keymap as usual.
+
+You can combine a .json based keymap with more advanced features specified in .c files
+  with a bit more complexity.
+For example, see
+[pierrec83's Kyria map](https://github.com/qmk/qmk_firmware/tree/master/keyboards/splitkb/kyria/keymaps/pierrec83).
