 ## Programming The Behavior Of Any Keycode
 
-When you want to override the behavior of an existing key, or define the behavior for a new key, you should use the `process_record_kb()' and `process_record_user()` functions. These are called by QMK during key processing before the actual key event is handled. If these functions return `true` QMK will process the keycodes as usual. That can be handy for extending the functionality of a key rather than replacing it. If these functions return `false` QMK will skip the normal key handling, and it will be up you to send any key up or down events that are required.

 ## Audio output from a speaker
 
-Your keyboard can make sounds! If you've got a Planck, Preonic, or basically any keyboard that allows access to the C6 or B5 port (`#define C6_AUDIO` and `#define B5_AUDIO`), you can hook up a simple speaker and make it beep. You can use those beeps to indicate layer transitions, modifiers, special keys, or just to play some funky 8bit tunes.
+Your keyboard can make sounds! If you've got a Planck, Preonic, or basically any AVR keyboard that allows access to the C6 or B5 port (`#define C6_AUDIO` and/or `#define B5_AUDIO`), you can hook up a simple speaker and make it beep. You can use those beeps to indicate layer transitions, modifiers, special keys, or just to play some funky 8bit tunes.
 
-The audio code lives in [quantum/audio/audio.h](https://github.com/qmk/qmk_firmware/blob/master/quantum/audio/audio.h) and in the other files in the audio directory. It's enabled by default on the Planck [stock keymap](https://github.com/qmk/qmk_firmware/blob/master/keyboards/planck/keymaps/default/keymap.c). Here are the important bits:
+If you add `AUDIO_ENABLE = yes` to your `rules.mk`, there's a couple different sounds that will automatically be enabled without any other configuration:
 
 ```
-#include "audio.h"
+STARTUP_SONG // plays when the keyboard starts up (audio.c)
+GOODBYE_SONG // plays when you press the RESET key (quantum.c)
+AG_NORM_SONG // plays when you press AG_NORM (quantum.c)
+AG_SWAP_SONG // plays when you press AG_SWAP (quantum.c)
+MUSIC_ON_SONG // plays when music mode is activated (process_music.c)
+MUSIC_OFF_SONG // plays when music mode is deactivated (process_music.c)
+CHROMATIC_SONG // plays when the chromatic music mode is selected (process_music.c)
+GUITAR_SONG // plays when the guitar music mode is selected (process_music.c)
+VIOLIN_SONG // plays when the violin music mode is selected (process_music.c)
+MAJOR_SONG // plays when the major music mode is selected (process_music.c)
 ```
 
-Then, lower down the file:
+You can override the default songs by doing something like this in your `config.h`:
 
-```
-float tone_startup[][2] = {
-    ED_NOTE(_E7 ),
-    E__NOTE(_CS7),
-    E__NOTE(_E6 ),
-    E__NOTE(_A6 ),
-    M__NOTE(_CS7, 20)
-};
+```c
+#ifdef AUDIO_ENABLE
+  #define STARTUP_SONG SONG(STARTUP_SOUND)
+#endif
 ```
 
-This is how you write a song. Each of these lines is a note, so we have a little ditty composed of five notes here.
+A full list of sounds can be found in [quantum/audio/song_list.h](https://github.com/qmk/qmk_firmware/blob/master/quantum/audio/song_list.h) - feel free to add your own to this list! All available notes can be seen in [quantum/audio/musical_notes.h](https://github.com/qmk/qmk_firmware/blob/master/quantum/audio/musical_notes.h).
 
-Then, we have this chunk:
+To play a custom sound at a particular time, you can define a song like this (near the top of the file):
 
-```
-float tone_qwerty[][2]     = SONG(QWERTY_SOUND);
-float tone_dvorak[][2]     = SONG(DVORAK_SOUND);
-float tone_colemak[][2]    = SONG(COLEMAK_SOUND);
-float tone_plover[][2]     = SONG(PLOVER_SOUND);
-float tone_plover_gb[][2]  = SONG(PLOVER_GOODBYE_SOUND);
-
-float music_scale[][2] = SONG(MUSIC_SCALE_SOUND);
-float goodbye[][2] = SONG(GOODBYE_SOUND);
+```c
+float my_song[][2] = SONG(QWERTY_SOUND);
 ```
 
-Wherein we bind predefined songs (from [quantum/audio/song_list.h](https://github.com/qmk/qmk_firmware/blob/master/quantum/audio/song_list.h)) into named variables. This is one optimization that helps save on memory: These songs only take up memory when you reference them in your keymap, because they're essentially all preprocessor directives.
+And then play your song like this:
 
-So now you have something called `tone_plover` for example. How do you make it play the Plover tune, then? If you look further down the keymap, you'll see this:
-
-```
-PLAY_NOTE_ARRAY(tone_plover, false, 0); // Signature is: Song name, repeat, rest style
+```c
+PLAY_SONG(my_song);
 ```
 
-This is inside one of the macros. So when that macro executes, your keyboard plays that particular chime.
+Alternatively, you can play it in a loop like this:
 
-"Rest style" in the method signature above (the last parameter) specifies if there's a rest (a moment of silence) between the notes.
+```c
+PLAY_LOOP(my_song);
+```
+
+It's advised that you wrap all audio features in `#ifdef AUDIO_ENABLE` / `#endif` to avoid causing problems when audio isn't built into the keyboard.

 * `KC_UP` - speed-up playback
 * `KC_DOWN` - slow-down playback
 
+By default, `MUSIC_MASK` is set to `keycode < 0xFF` which means keycodes less than `0xFF` are turned into notes, and don't output anything. You can change this by defining this in your `config.h` like this:
+
+    #define MUSIC_MASK keycode != KC_NO
+
+Which will capture all keycodes - be careful, this will get you stuck in music mode until you restart your keyboard!
+
+The pitch standard (`PITCH_STANDARD_A`) is 440.0f by default - to change this, add something like this to your `config.h`:

+MiniDox
+=====
+
+![MimiDox](http://i.imgur.com/iWb3yO0.jpg)
+
+A compact version of the ErgoDox
+
+Keyboard Maintainer: That-Canadian
+Hardware Supported: MiniDox PCB rev1 Pro Micro
+
+Make example for this keyboard (after setting up your build environment):
+
+    make minidox-rev1-default
+
+See [build environment setup](https://docs.qmk.fm/build_environment_setup.html) then the [make instructions](https://docs.qmk.fm/make_instructions.html) for more information.
+
+## Build Guide
+
+A build guide for putting together the MiniDox v1 can be found here: [MiniDox Build Log / Guide](http://imgur.com/a/vImo6)
+
+Flashing
+-------
+Note: Most of this is copied from the Let's Split readme, because it is awesome
+
+From the keymap directory run `make SUBPROJECT-KEYMAP-avrdude` for automatic serial port resolution and flashing.
+Example: `make rev1-default-avrdude`
+
+Choosing which board to plug the USB cable into (choosing Master)
+--------
+Because the two boards are identical, the firmware has logic to differentiate the left and right board.
+
+It uses two strategies to figure things out: look at the EEPROM (memory on the chip) or looks if the current board has the usb cable.
+
+The EEPROM approach requires additional setup (flashing the eeeprom) but allows you to swap the usb cable to either side.
+
+The USB cable approach is easier to setup and if you just want the usb cable on the left board, you do not need to do anything extra.
+
+### Setting the left hand as master
+If you always plug the usb cable into the left board, nothing extra is needed as this is the default. Comment out `EE_HANDS` and comment out `I2C_MASTER_RIGHT` or `MASTER_RIGHT` if for some reason it was set.
+
+### Setting the right hand as master
+If you always plug the usb cable into the right board, add an extra flag to your `config.h`
+```
+ #define MASTER_RIGHT
+```
+
+### Setting EE_hands to use either hands as master
+If you define `EE_HANDS` in your `config.h`, you will need to set the
+EEPROM for the left and right halves.
+
+The EEPROM is used to store whether the
+half is left handed or right handed. This makes it so that the same firmware
+file will run on both hands instead of having to flash left and right handed
+versions of the firmware to each half. To flash the EEPROM file for the left
+half run:
+```
+avrdude -p atmega32u4 -P $(COM_PORT) -c avr109 -U eeprom:w:eeprom-lefthand.eep
+// or the equivalent in dfu-programmer
+
+```
+and similarly for right half
+```
+avrdude -p atmega32u4 -P $(COM_PORT) -c avr109 -U eeprom:w:eeprom-righhand.eep
+// or the equivalent in dfu-programmer
+```
+
+NOTE: replace `$(COM_PORT)` with the port of your device (e.g. `/dev/ttyACM0`)
+
+After you have flashed the EEPROM, you then need to set `EE_HANDS` in your config.h, rebuild the hex files and reflash.
+
+Note that you need to program both halves, but you have the option of using
+different keymaps for each half. You could program the left half with a QWERTY
+layout and the right half with a Colemak layout using bootmagic's default layout option.
+Then if you connect the left half to a computer by USB the keyboard will use QWERTY and Colemak when the
+right half is connected.
