-Alternative Controller for HHKB Pro
-===================================
-I wanted to add some features like vi cursor and mouse keys to my [HHKB][HHKB] but its controller is not programmable and
-firmware source code is not open, of course. This means customizing this keyboard needs to replace original
-controller with programmable one. For this purpose I used PJRC [Teensy++][Teensy] as alternative controller.

+## Quantum MK Firmware
+You have access to a bunch of goodies! Check out the Makefile to enable/disable some of the features. Uncomment the `#` to enable them. Setting them to `no` does nothing and will only confuse future you.
-My keyboard firmware source tree is here: http://github.com/tmk/tmk_keyboard
-See directory keyboard/hhkb to build firmware for HHKB.
+ BACKLIGHT_ENABLE = yes # Enable keyboard backlight functionality
+ MIDI_ENABLE = yes # MIDI controls
+ # UNICODE_ENABLE = yes # Unicode support - this is commented out, just as an example. You have to use #, not //
+ BLUETOOTH_ENABLE = yes # Enable Bluetooth with the Adafruit EZ-Key HID
+## Quick aliases to common actions
-##Features
-* Customizable keymap
-* More keymap layers(more Fn keys)
-* Mouse keys
-* USB NKRO
+Your keymap can include shortcuts to common operations (called "function actions" in tmk).
-###Pros
-* Without PCB trace cutting, case mod or any destructives
-* Can keep original controller intact
-* Can change all HHKB behaviour as you like
+### Switching and toggling layers
-###Cons
-* Void your warranty
-* Lose USB hub function in case of Pro2
+`MO(layer)` - momentary switch to *layer*. As soon as you let go of the key, the layer is deactivated and you pop back out to the previous layer. When you apply this to a key, that same key must be set as `KC_TRNS` on the destination layer. Otherwise, you won't make it back to the original layer when you release the key (and you'll get a keycode sent). You can only switch to layers *above* your current layer. If you're on layer 0 and you use `MO(1)`, that will switch to layer 1 just fine. But if you include `MO(3)` on layer 5, that won't do anything for you -- because layer 3 is lower than layer 5 on the stack.
-##DISCLAIMER
-I'm not a professional of electronics or MCU programming. This may damage your HHKB.
-And my English writing is poor, I'm not sure I can convey my notions accurately.
+`LT(layer, kc)` - momentary switch to *layer* when held, and *kc* when tapped. Like `MO()`, this only works upwards in the layer stack (`layer` must be higher than the current layer).
+`TG(layer)` - toggles a layer on or off. As with `MO()`, you should set this key as `KC_TRNS` in the destination layer so that tapping it again actually toggles back to the original layer. Only works upwards in the layer stack.
+### Fun with modifier keys
+* `LSFT(kc)` - applies left Shift to *kc* (keycode) - `S(kc)` is an alias
+* `RSFT(kc)` - applies right Shift to *kc*
+* `LCTL(kc)` - applies left Control to *kc*
+* `RCTL(kc)` - applies right Control to *kc*
+* `LALT(kc)` - applies left Alt to *kc*
+* `RALT(kc)` - applies right Alt to *kc*
+* `LGUI(kc)` - applies left GUI (command/win) to *kc*
+* `RGUI(kc)` - applies right GUI (command/win) to *kc*
+You can also chain these, like this:
+ LALT(LCTL(KC_DEL)) -- this makes a key that sends Alt, Control, and Delete in a single keypress.
-##Build Firmware
-You can choose some combination of MCU and USB protocol stack.
+The following shortcuts automatically add `LSFT()` to keycodes to get commonly used symbols. Their long names are also available and documented in `/quantum/keymap_common.h`.

-1. Edit **keymap.c** to use your favoirte keymap.
+`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.
-2. Edit **Makefile** if you want to use other `MCU` than Teensy++ 2.0.
+These are the values you can use for the `mod` in `MT()` (right-hand modifiers are not available):
-3. Build firmware binary file:
- `$ make -f Makefile.lufa`
+ * MOD_LCTL
+ * MOD_LSFT
+ * MOD_LALT
+ * MOD_LGUI
-4. Program MCU with PJRC [Teensy Loader] tool. If you install command line version of the loader just run:
- `$ make -f Makefile.lufa teensy`
+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.

-[Teensy Loader]: http://www.pjrc.com/teensy/loader.html
+We've added shortcuts to make common modifier/tap (mod-tap) mappings more compact:
+ * `CTL_T(kc)` - is LCTL when held and *kc* when tapped
+ * `SFT_T(kc)` - is LSFT when held and *kc* when tapped
+ * `ALT_T(kc)` - is LALT when held and *kc* when tapped
+ * `GUI_T(kc)` - is LGUI when held and *kc* when tapped
+ * `ALL_T(kc)` - is Hyper (all mods) when held and *kc* when tapped. To read more about what you can do with a Hyper key, see [this blog post by Brett Terpstra](http://brettterpstra.com/2012/12/08/a-useful-caps-lock-key/)
-###AVR Mega with [V-USB]
-Follow below if you want to use AVR with V-USB as .
+### Temporarily setting the default layer
-0. Edit **matrix.c** to use your pin configuration. See doc/HHKB.txt for detail.
+`DF(layer)` - sets default layer to *layer*. The default layer is the one at the "bottom" of the layer stack - the ultimate fallback layer. This currently does not persist over power loss. When you plug the keyboard back in, layer 0 will always be the default. It is theoretically possible to work around that, but that's not what `DF` does.
-1. Edit **keymap.c** to use your favoirte keymap.
+### Remember: These are just aliases
-2. Edit **usbconfig.h** to configure V-USB options.
+These functions work the same way that their `ACTION_*` functions do - they're just quick aliases. To dig into all of the tmk ACTION_* functions, please see the [TMK documentation](https://github.com/jackhumbert/qmk_firmware/blob/master/tmk_core/doc/keymap.md#2-action).
-3. Edit **Makefile.vusb** to define `MCU` and `F_CPU`.
+Instead of using `FNx` when defining `ACTION_*` functions, you can use `F(x)` - the benefit here is being able to use more than 32 function actions (up to 4096), if you happen to need them.
-4. Build firmware binary file:
- `$ make -f Makefile.vusb`
+## Macro shortcuts: Send a whole string when pressing just one key
-5. Program MCU with AVR programmer like AVRISPmkII. If you already have [USBaspLoader] on MCU just run:
- `$ make -f Makefile.vusb program`
+Instead of using the `ACTION_MACRO` function, you can simply use `M(n)` to access macro *n* - *n* will get passed into the `action_get_macro` as the `id`, and you can use a switch statement to trigger it. This gets called on the keydown and keyup, so you'll need to use an if statement testing `record->event.pressed` (see keymap_default.c).
-[V-USB]: http://www.obdev.at/products/vusb/index.html
-[USBaspLoader]: http://www.obdev.at/products/vusb/usbasploader.html
+```c
+const macro_t *action_get_macro(keyrecord_t *record, uint8_t id, uint8_t opt) // this is the function signature -- just copy/paste it into your keymap file as it is.
+{
+ switch(id) {
+ case 0: // this would trigger when you hit a key mapped as M(0)
+ if (record->event.pressed) {
+ return MACRO( I(255), T(H), T(E), T(L), T(L), W(255), T(O), END ); // this sends the string 'hello' when the macro executes
+ }
+ break;
+ }
+ return MACRO_NONE;
+};
+```
+A macro can include the following commands:
+* I() change interval of stroke in milliseconds.
+* D() press key.
+* U() release key.
+* T() type key(press and release).
+* W() wait (milliseconds).
+* END end mark.
-###How to Customize Keymap
-Later...
-See **keymap.c**.
+So above you can see the stroke interval changed to 255ms between each keystroke, then a bunch of keys being typed, waits a while, then the macro ends.
+Note: Using macros to have your keyboard send passwords for you is a bad idea.
-##Hardware
+### Additional keycode aliases for software-implemented layouts (Colemak, Dvorak, etc)
-###Teensy++ installation
-Angled USB mini B adapter is used to install Teensy++ laterally.
-![Teensy install](doc/HHKB_img/teensy_install.jpg)
+Everything is assuming you're in Qwerty (in software) by default, but there is built-in support for using a Colemak or Dvorak layout by including this at the top of your keymap:
-Bread baord wires are used to connect Teensy++.
-![Teensy wiring](doc/HHKB_img/teensy_wiring.jpg)
-![Connector](doc/HHKB_img/connector_contact.jpg)
+ #include "keymap_<layout>.h"
+Where <layout> is "colemak" or "dvorak". After including this line, you will get access to:
+
+ * `CM_*` for all of the Colemak-equivalent characters
+ * `DV_*` for all of the Dvorak-equivalent characters
+
+These implementations assume you're using Colemak or Dvorak on your OS, not on your keyboard - this is referred to as a software-implemented layout. If your computer is in Qwerty and your keymap is in Colemak or Dvorak, this is referred to as a firmware-implemented layout, and you won't need these features.

+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 `รน` when using a software-implemented AZERTY layout. It's currently difficult to send such characters in just the firmware (but it's being worked on - see Unicode support).
+
+## Unicode support
+
+You can currently send 4 hex digits with your OS-specific modifier key (RALT for OSX with the "Unicode Hex Input" layout) - this is currently limited to supporting one OS at a time, and requires a recompile for switching. 8 digit hex codes are being worked on. The keycode function is `UC(n)`, where *n* is a 4 digit hexidecimal. Enable from the Makefile.
+
+## Other firmware shortcut keycodes
+
+* `RESET` - puts the MCU in DFU mode for flashing new firmware (with `make dfu`)
+* `DEBUG` - the firmware into debug mode - you'll need hid_listen to see things
+* `BL_ON` - turns the backlight on
+* `BL_OFF` - turns the backlight off
+* `BL_<n>` - sets the backlight to level *n*
+* `BL_INC` - increments the backlight level by one
+* `BL_DEC` - decrements the backlight level by one
+* `BL_TOGG` - toggles the backlight
+* `BL_STEP` - steps through the backlight levels
+
+Enable the backlight from the Makefile.
+
+## MIDI functionalty
+
+This is still a WIP, but check out `quantum/keymap_midi.c` to see what's happening. Enable from the Makefile.
+
+## Bluetooth functionality
+
+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.
+
+## Building
+
+Download or clone the whole firmware and navigate to the keyboard/planck folder. Once your dev env is setup, you'll be able to type `make` to generate your .hex - you can then use `make dfu` to program your PCB once you hit the reset button.
+
+Depending on which keymap you would like to use, you will have to compile slightly differently.
+
+### Default
+To build with the default keymap, simply run `make`.
+
+### Other Keymaps
+Several version of keymap are available in advance but you are recommended to define your favorite layout yourself. To define your own keymap create a file in the keymaps folder named `<name>.c` and see keymap document (you can find in top README.md) and existent keymap files.
+
+To build the firmware binary hex file with a keymap just do `make` with `KEYMAP` option like:
+```
+$ make KEYMAP=[default|jack|<name>]
+```
+Keymaps follow the format **__\<name\>.c__** and are stored in the `keymaps` folder.
