+
+### 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
+   * For boards with DFU bootloader you can use `:dfu-split-left`/`:dfu-split-right` to flash these EEPROM files
+   * For boards with Caterina bootloader (like stock Pro Micros), use `:avrdude-split-left`/`:avrdude-split-right`
+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
+
+#### Defines for handedness
+
 * `#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 you can still use the EEHANDS method or MASTER_LEFT / MASTER_RIGHT defines like the stock Let's Split uses.
-  
+  * 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 RGBLED_SPLIT { 6, 6 }`
+  * See [RGB Light Configuration](#rgb-light-configuration)
+
+* `#define SELECT_SOFT_SERIAL_SPEED <speed>` (default speed is 1)
+  * Sets the protocol speed when using serial communication
+  * Speeds:
+    * 0: about 189kbps (Experimental only)

   * Enables split keyboard support (dual MCU like the let's split and bakingpy's boards) and includes all necessary files located at quantum/split_common
+* `CUSTOM_MATRIX`
+  * Allows replacing the standard matrix scanning routine with a custom one.
+* `DEBOUNCE_TYPE`
+  * Allows replacing the standard key debouncing routine with an alternative or custom one.
 * `WAIT_FOR_USB`
   * Forces the keyboard to wait for a USB connection to be established before it starts up
 * `NO_USB_STARTUP_CHECK`
   * Disables usb suspend check after keyboard startup. Usually the keyboard waits for the host to wake it up before any tasks are performed. This is useful for split keyboards as one half will not get a wakeup call but must send commands to the master.

+## 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.

+# Auto-formatting with clang-format
+
+[Clang-format](https://clang.llvm.org/docs/ClangFormat.html) is part of LLVM and can automatically format your code for you, because ain't nobody got time to do it manually. We supply a configuration file for it that applies most of the coding conventions listed above. It will only change whitespace and newlines, so you will still have to remember to include optional braces yourself.
+
+Use the [full LLVM installer](http://llvm.org/builds/) to get clang-format on Windows, or use `sudo apt install clang-format` on Ubuntu.
+
+If you run it from the command-line, pass `-style=file` as an option and it will automatically find the .clang-format configuration file in the QMK root directory.
+
+If you use VSCode, the standard C/C++ plugin supports clang-format, alternatively there is a [separate extension](https://marketplace.visualstudio.com/items?itemName=LLVMExtensions.ClangFormat) for it.
+
+Some things (like LAYOUT macros) are destroyed by clang-format, so either don't run it on those files, or wrap the sensitive code in `// clang-format off` and `// clang-format on`.

-These functions allow you to activate layers in various ways. Note that layers are not generally independent layouts -- multiple layers can be activated at once, and it's typical for layers to use `KC_TRNS` to allow keypresses to pass through to lower layers.

For a detailed explanation of layers, see [Keymap Overview](keymap.md#keymap-and-layers). When using momentary layer switching with MO(), LM(), TT(), or LT(), make sure to leave the key on the above layers transparent or it may not work as intended.
 
 * `DF(layer)` - switches the default layer. The default layer is the always-active base layer that other layers stack on top of. See below for more about the default layer. This might be used to switch from QWERTY to Dvorak layout. (Note that this is a temporary switch that only persists until the keyboard loses power. To modify the default layer in a persistent way requires deeper customization, such as calling the `set_single_persistent_default_layer` function inside of [process_record_user](custom_quantum_functions.md#programming-the-behavior-of-any-keycode).)
 * `MO(layer)` - momentarily activates *layer*. As soon as you let go of the key, the layer is deactivated. 
-* `LM(layer, mod)` - Momentarily activates *layer* (like `MO`), but with modifier(s) *mod* active. Only supports layers 0-15 and the left modifiers.

+## Callbacks
 
-# Permissive Hold
+When you'd like to perform custom logic when pressing a one shot key, there are several callbacks you can choose to implement. You could indicate changes in one shot keys by flashing an LED or making a sound, for example.
+
+There is a callback for `OSM(mod)`. It is called whenever the state of any one shot modifier key is changed: when it toggles on, but also when it is toggled off. You can use it like this:
+
+```c
+void oneshot_mods_changed_user(uint8_t mods) {
+  if (mods & MOD_MASK_SHIFT) {
+    println("Oneshot mods SHIFT");
+  }
+  if (mods & MOD_MASK_CTRL) {
+    println("Oneshot mods CTRL");
+  }
+  if (mods & MOD_MASK_ALT) {
+    println("Oneshot mods ALT");
+  }
+  if (mods & MOD_MASK_GUI) {
+    println("Oneshot mods GUI");
+  }
+  if (!mods) {
+    println("Oneshot mods off");
+  }
+}
+```
+
+The `mods` argument contains the active mods after the change, so it reflects the current state.
+
+When you use One Shot Tap Toggle (by adding `#define ONESHOT_TAP_TOGGLE 2` in your `config.h` file), you may lock a modifier key by pressing it the specified amount of times. There's a callback for that, too:
+
+```c
+void oneshot_locked_mods_changed_user(uint8_t mods) {
+  if (mods & MOD_MASK_SHIFT) {
+    println("Oneshot locked mods SHIFT");
+  }
+  if (mods & MOD_MASK_CTRL) {
+    println("Oneshot locked mods CTRL");
+  }
+  if (mods & MOD_MASK_ALT) {
+    println("Oneshot locked mods ALT");
+  }
+  if (mods & MOD_MASK_GUI) {
+    println("Oneshot locked mods GUI");
+  }
+  if (!mods) {
+    println("Oneshot locked mods off");
+  }
+}
+```
+
+Last, there is also a callback for the `OSL(layer)` one shot key:
+
+```c
+void oneshot_layer_changed_user(uint8_t layer) {
+  if (layer == 1) {
+    println("Oneshot layer 1 on");
+  }
+  if (!layer) {
+    println("Oneshot layer off");
+  }
+}
+```
+
+If any one shot layer is switched off, `layer` will be zero. When you're looking to do something on any layer change instead of one shot layer changes, `layer_state_set_user` is a better callback to use.
+
+If you are making your own keyboard, there are also `_kb` equivalent functions:
+
+```c
+void oneshot_locked_mods_changed_kb(uint8_t mods);
+void oneshot_mods_changed_kb(uint8_t mods);
+void oneshot_layer_changed_kb(uint8_t layer);
+```
+
+As with any callback, be sure to call the `_user` variant to allow for further customizability.

-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
+```
 
-# Hold after tap
+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. 
 
-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`.
+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`.
+
+## Tapping Force Hold
+
+To enable `tapping force hold`, add the following to your `config.h`: 
+
+```c
+#define 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.

+# Debounce algorithm
+
+QMK supports multiple debounce algorithms through its debounce API.
+
+The logic for which debounce method called is below. It checks various defines that you have set in rules.mk
+
+```
+DEBOUNCE_DIR:= $(QUANTUM_DIR)/debounce
+DEBOUNCE_TYPE?= sym_g
+ifneq ($(strip $(DEBOUNCE_TYPE)), custom)
+    QUANTUM_SRC += $(DEBOUNCE_DIR)/$(strip $(DEBOUNCE_TYPE)).c
+endif
+```
+
+# Debounce selection
+
+| DEBOUNCE_TYPE    | Description                                          | What else is needed           |
+| -------------    | ---------------------------------------------------  | ----------------------------- |
+| Not defined      | Use the default algorithm, currently sym_g           | Nothing                       |
+| custom           | Use your own debounce.c                              | ```SRC += debounce.c``` add your own debounce.c and implement necessary functions |
+| anything_else    | Use another algorithm from quantum/debounce/*        | Nothing                       |
+
+**Regarding split keyboards**:
+The debounce code is compatible with split keyboards.
+
+# Use your own debouncing code
+* Set ```DEBOUNCE_TYPE = custom ```.
+* Add ```SRC += debounce.c```
+* Add your own ```debounce.c```. Look at current implementations in ```quantum/debounce``` for examples.
+* Debouncing occurs after every raw matrix scan.
+* Use num_rows rather than MATRIX_ROWS, so that split keyboards are supported correctly.
+
+# Changing between included debouncing methods
+You can either use your own code, by including your own debounce.c, or switch to another included one.
+Included debounce methods are:
+* eager_pr - debouncing per row. On any state change, response is immediate, followed by locking the row ```DEBOUNCE_DELAY``` milliseconds of no further input for that row. 
+For use in keyboards where refreshing ```NUM_KEYS``` 8-bit counters is computationally expensive / low scan rate, and fingers usually only hit one row at a time. This could be
+appropriate for the ErgoDox models; the matrix is rotated 90°, and hence its "rows" are really columns, and each finger only hits a single "row" at a time in normal use.
+* eager_pk - debouncing per key. On any state change, response is immediate, followed by ```DEBOUNCE_DELAY``` milliseconds of no further input for that key
+* sym_g - debouncing per keyboard. On any state change, a global timer is set. When ```DEBOUNCE_DELAY``` milliseconds of no changes has occured, all input changes are pushed.
