 QMK can leverage the Analog-to-Digital Converter (ADC) on supported MCUs to measure voltages on certain pins. This can be useful for implementing things such as battery level indicators for Bluetooth keyboards, or volume controls using a potentiometer, as opposed to a [rotary encoder](feature_encoders.md).
 
-This driver is currently AVR-only. The values returned are 10-bit integers (0-1023) mapped between 0V and VCC (usually 5V or 3.3V).
+This driver currently supports both AVR and a limited selection of ARM devices. On AVR devices, the values returned are 10-bit integers (0-1023) mapped between 0V and VCC (usually 5V or 3.3V). On supported ARM devices, there is more flexibility in control of operation through `#define`s, but by default the values returned are 12-bit integers (0-4095) mapped between 0V and VCC (usually 3.3V).

+### ARM
+
+Note that care was taken to match all of the functions used for AVR devices, however complications in the ARM platform prevent that from always being possible. For example, the `STM32` chips do not have assigned Arduino pins. We could use the default pin numbers, but those numbers change based on the package type of the device. For this reason, please specify your target pins with their identifiers (`A0`, `F3`, etc.). Also note that there are some variants of functions that accept the target ADC for the pin. Some pins can be used for multiple ADCs, and this specified can help you pick which ADC will be used to interact with that pin.

+|ADC_BUFFER_DEPTH   |`int` |`2`                  |Sets the depth of each result. Since we are only getting a 12-bit result by default, we set this to `2` bytes so we can contain our one value. This could be set to 1 if you opt for a 8-bit or lower result.|
+|ADC_SAMPLING_RATE  |`int` |`ADC_SMPR_SMP_1P5`   |Sets the sampling rate of the ADC. By default, it is set to the fastest setting. Please consult the corresponding `hal_adc_lld.h` in ChibiOS for your specific microcontroller for further documentation on your available options.|

 * Setting `MOUSEKEY_DELAY` too low makes the cursor unresponsive. Setting it too high makes small movements difficult.
 * For smoother cursor movements, lower the value of `MOUSEKEY_INTERVAL`. If the refresh rate of your display is 60Hz, you could set it to `16` (1/60). As this raises the cursor speed significantly, you may want to lower `MOUSEKEY_MAX_SPEED`.
 * Setting `MOUSEKEY_TIME_TO_MAX` or `MOUSEKEY_WHEEL_TIME_TO_MAX` to `0` will disable acceleration for the cursor or scrolling respectively. This way you can make one of them constant while keeping the other accelerated, which is not possible in constant speed mode.

 Cursor acceleration uses the same algorithm as the X Window System MouseKeysAccel feature. You can read more about it [on Wikipedia](https://en.wikipedia.org/wiki/Mouse_keys).

+
+To define a layer, we modify `keymap.c` to list out LED ranges and the colors we want to overlay on them using an array of `rgblight_segment_t` using the `RGBLIGHT_LAYER_SEGMENTS` macro. We can define multiple layers and enable/disable them independently:
+
+```c
+// Light LEDs 6 to 9 and 12 to 15 red when caps lock is active. Hard to ignore!
+const rgblight_segment_t PROGMEM my_capslock_layer[] = RGBLIGHT_LAYER_SEGMENTS(
+	{6, 4, HSV_RED},       // Light 4 LEDs, starting with LED 6
+	{12, 4, HSV_RED}       // Light 4 LEDs, starting with LED 12
+);
+// Light LEDs 9 & 10 in cyan when keyboard layer 1 is active
+const rgblight_segment_t PROGMEM my_layer1_layer[] = RGBLIGHT_LAYER_SEGMENTS(
+	{9, 2, HSV_CYAN}
+);
+// Light LEDs 11 & 12 in purple when keyboard layer 2 is active
+const rgblight_segment_t PROGMEM my_layer2_layer[] = RGBLIGHT_LAYER_SEGMENTS(
+	{11, 2, HSV_PURPLE}, 
+);
+// etc..
+```
+
+We combine these layers into an array using the `RGBLIGHT_LAYERS_LIST` macro, and assign it to the `rgblight_layers` variable during keyboard setup. Note that you can only define up to 8 lighting layers. Any extra layers will be ignored. Since the different lighting layers overlap, the order matters in the array, with later layers taking precedence:
+
+```c
+// Now define the array of layers. Later layers take precedence
+const rgblight_segment_t* const PROGMEM my_rgb_layers[] = RGBLIGHT_LAYERS_LIST(
+	my_capslock_layer,
+	my_layer1_layer,    // Overrides caps lock layer
+	my_layer2_layer     // Overrides other layers
+);
+
+void keyboard_post_init_user(void) {
+	// Enable the LED layers
+	rgblight_layers = my_rgb_layers;
+}
+```
+
+Finally, we enable and disable the lighting layers whenever the state of the keyboard changes:
+
+```c
+layer_state_t layer_state_set_user(layer_state_t state) {
+	// Both layers will light up if both kb layers are active
+	rgblight_set_layer_state(1, layer_state_cmp(state, 1));
+	rgblight_set_layer_state(2, layer_state_cmp(state, 2));
+	return state;
+}
+
+bool led_update_user(led_t led_state) {
+	rgblight_set_layer_state(0, led_state.caps_lock);
+	return true;
+}
+```

 Plover can work with any standard QWERTY keyboard, although it is more efficient if the keyboard supports NKRO (n-key rollover) to allow Plover to see all the pressed keys at once. An example keymap for Plover can be found in `planck/keymaps/default`. Switching to the `PLOVER` layer adjusts the position of the keyboard to support the number bar.
 
 To use Plover with QMK just enable NKRO and optionally adjust your layout if you have anything other than a standard layout. You may also want to purchase some steno-friendly keycaps to make it easier to hit multiple keys.

 Firstly, enable steno in your keymap's Makefile. You may also need disable mousekeys, extra keys, or another USB endpoint to prevent conflicts. The builtin USB stack for some processors only supports a certain number of USB endpoints and the virtual serial port needed for steno fills 3 of them.

 In your keymap create a new layer for Plover. You will need to include `keymap_steno.h`. See `planck/keymaps/steno/keymap.c` for an example. Remember to create a key to switch to the layer as well as a key for exiting the layer. If you would like to switch modes on the fly you can use the keycodes `QK_STENO_BOLT` and `QK_STENO_GEMINI`. If you only want to use one of the protocols you may set it up in your initialization function:

-## Interfacing with the code
+## Interfacing with the code :id=interfacing-with-the-code
 
 The steno code has three interceptible hooks. If you define these functions, they will be called at certain points in processing; if they return true, processing continues, otherwise it's assumed you handled things.
 
-```C
+```c
 bool send_steno_chord_user(steno_mode_t mode, uint8_t chord[6]);
 ```
 
 This function is called when a chord is about to be sent. Mode will be one of `STENO_MODE_BOLT` or `STENO_MODE_GEMINI`. This represents the actual chord that would be sent via whichever protocol. You can modify the chord provided to alter what gets sent. Remember to return true if you want the regular sending process to happen.
 
-```C
+```c
 bool process_steno_user(uint16_t keycode, keyrecord_t *record) { return true; }
 ```
 
 This function is called when a keypress has come in, before it is processed. The keycode should be one of `QK_STENO_BOLT`, `QK_STENO_GEMINI`, or one of the `STN_*` key values.
 
-```C
+```c
 bool postprocess_steno_user(uint16_t keycode, keyrecord_t *record, steno_mode_t mode, uint8_t chord[6], int8_t pressed);
 ```
 
 This function is called after a key has been processed, but before any decision about whether or not to send a chord. If `IS_PRESSED(record->event)` is false, and `pressed` is 0 or 1, the chord will be sent shortly, but has not yet been sent. This is where to put hooks for things like, say, live displays of steno chords or keys.

+Github can be a little tricky to those that aren't familiar with it - this guide will walk through each step of forking, cloning, and submitting a pull request with QMK.
+
+?> This guide assumes you're somewhat comfortable with running things at the command line, and have git installed on your system.
+
+Start on the [QMK Github page](https://github.com/qmk/qmk_firmware), and you'll see a button in the upper right that says "Fork":
+
+![Fork on Github](http://i.imgur.com/8Toomz4.jpg)
+
+If you're a part of an organization, you'll need to choose which account to fork it to. In most circumstances, you'll want to fork it to your personal account. Once your fork is completed (sometimes this takes a little while), click the "Clone or Download" button:

 The I2C Master drivers used in QMK have a set of common functions to allow portability between MCUs.
 
-## Available functions
+## An important note on I2C Addresses :id=note-on-i2c-addresses
+
+All of the addresses expected by this driver should be pushed to the upper 7 bits of the address byte.  Setting
+the lower bit (indicating read/write) will be done by the respective functions.  Almost all I2C addresses listed 
+on datasheets and the internet will be represented as 7 bits occupying the lower 7 bits and will need to be
+shifted to the left (more significant) by one bit.  This is easy to do via the bitwise shift operator `<< 1`.
+
+You can either do this on each call to the functions below, or once in your definition of the address.  For example if your device has an address of `0x18`:
+
+`#define MY_I2C_ADDRESS (0x18 << 1)`
+
+See https://www.robot-electronics.co.uk/i2c-tutorial for more information about I2C addressing and other technical details.

-## Advanced Settings
+## Advanced Settings :id=advanced-settings
 
 Each microcontroller can have multiple advanced settings regarding its GPIO. This abstraction layer does not limit the use of architecture-specific functions. Advanced users should consult the datasheet of their desired device and include any needed libraries. For AVR, the standard avr/io.h library is used; for STM32, the ChibiOS [PAL library](http://chibios.sourceforge.net/docs3/hal/group___p_a_l.html) is used.
