+Pointing devices can now be shared across a split keyboard with support for a single pointing device or a pointing device on each side.
+
+This feature can be enabled with `#define SPLIT_POINTING_ENABLE` and one of the following options:

 ## Modifier Combos
 If a combo resolves to a Modifier, the window for processing the combo can be extended independently from normal combos. By default, this is disabled but can be enabled with `#define COMBO_MUST_HOLD_MODS`, and the time window can be configured with `#define COMBO_HOLD_TERM 150` (default: `TAPPING_TERM`). With `COMBO_MUST_HOLD_MODS`, you cannot tap the combo any more which makes the combo less prone to misfires.

+By defining `COMBO_MUST_PRESS_IN_ORDER` combos only activate when the keys are pressed in the same order as they are defined in the key array.
 
-For example, tap-only combos are useful if any (or all) of the underlying keys is a Mod-Tap or a Layer-Tap key. When you tap the combo, you get the combo result. When you press the combo and hold it down, the combo doesn't actually activate. Instead the keys are processed separately as if the combo wasn't even there.

+## Generic hook to (dis)allow a combo activation
+
+By defining `COMBO_SHOULD_TRIGGER` and its companying function `bool combo_should_trigger(uint16_t combo_index, combo_t *combo, uint16_t keycode, keyrecord_t *record)` you can block or allow combos to activate on the conditions of your choice.
+For example, you could disallow some combos on the base layer and allow them on another. Or disable combos on the home row when a timer is running.
+
+Examples:
+```c
+bool combo_should_trigger(uint16_t combo_index, combo_t *combo, uint16_t keycode, keyrecord_t *record) {
+    /* Disable combo `SOME_COMBO` on layer `_LAYER_A` */
+    switch (combo_index) {
+        case SOME_COMBO:
+            if (layer_state_is(_LAYER_A)) {
+                return false;
+            }
+    }
+
+    return true;
+}

 ### Custom data sync between sides :id=custom-data-sync
 
 QMK's split transport allows for arbitrary data transactions at both the keyboard and user levels. This is modelled on a remote procedure call, with the master invoking a function on the slave side, with the ability to send data from master to slave, process it slave side, and send data back from slave to master.

+== Layout
+Based on the stock layout but making use of CAPS as FN similar to laptop keyboards.
+This frees up the left row for other uses (although not remapped yet).
+Since both Delete and Insert are used for coding they are part of the CAPS layer as well.
+
+The differences are as follows:
+
+=== Layer 0 (`_BASE`)
+Mostly stock + CAPS goes to layer `_MOV`.
+FN toggles the layer `_RGB`.
+
+=== Layer 1 (`_MOV`), accessed by pressing `CAPS` on layer `_BASE`
+[%header]

+
+== RGB light
+
+The code customizing RGB light usage is decribed here:
+
+* link:../../../../../../users/vitoni/readme.adoc[/users/vitoni/readme.adoc]
+
+When using  `RGB_DISABLE_TIMEOUT` addtional options are available:
+
+* `RGB_FADE_IN` makes the RGB lights fade in instead of setting the value/brightness to 100% (implicitly due to HSV including the brightness) when resuming after RGB lights have been turned off.
+Fade in occurs when the keyboard is initialized and when the RGB brightness has been changed (e.g. suspending, fade out, etc.).
+* `RGB_DISABLE_WITH_FADE_OUT` activates fade out before the keyboard is disabled by `RGB_DISABLE_TIMEOUT`.
+
+Parameters used to define the behavior are:
+[%header]
+|===
+|Key | Default | Description
+
+| RGB_MATRIX_MAXIMUM_BRIGHTNESS
+| 200 (&lt;= UNIT8_MAX)
+| Maximum assumed value for brightness.
+Used to calculate lead time for fade out before suspend timeout.
+
+|===
+
+`RGB_IDLE_TIMEOUT` enables fading out after being idle for the defined time and allows
+* `RGB_IDLE_BREATHE` also activates a brethe effect while idling.
+
+[%header]
+|===
+|Key | Default | Description
+
+|RGB_IDLE_TIMEOUT
+|4500
+|Time in milliseconds without activity before considered to be idle.
+
+|RGB_IDLE_MINIMUM_BRIGHTNESS
+|`RGB_MATRIX_MAXIMUM_BRIGHTNESS` / 5
+|Brightness value RGB is dimmed to when starting to idle. +
+When breathing used as the lower bound of the brightness value.
+
+|RGB_IDLE_MAXIMUM_BRIGHTNESS
+|`RGB_MATRIX_MAXIMUM_BRIGHTNESS` * 2/5
+|Upper bound of brightness value of the RGB light while breathing.

-# Just60
-
-Just60 keyboard produced by Yang. The keyboard comes with a custom Mass Storage Device bootloader and a TMK based firmware from ydkb.io.
-
-To use a QMK based firmware, you might want to install a QMK bootloader. The PCB exposes 6 pins for ISP(In-System Programming), and they are located just under the ATMega32U4 chip. From left to right, the pins are `VCC`, `SCLK`, `MOSI`, `MISO`, `RESET`, `GND`. The `GND` is the square one. You could program the flash with any AVR programmer, or a Raspberry Pi with `avrdude`.
-
-Backlight LEDs and Bluetooth are not working yet.

-My first custom mech design. 4x10(ish), pro micro based, unibody, split, ortho (any more adjectives?), with OLED and (optional) rotary encoder.
-
-![Default layout](https://i.imgur.com/rCOwsoy.png)
-This is the default layout, at least the base layer. By default the OLED displays "rainkeeb" at the top in case you forget what you're typing on, a layer indicator below that (Default, Raised, Alt), and a WPM counter below that. Encoder toggles Play/Pause on click on the Default and Raised layers, and is supposed to RESET into flash-mode on the Alt layer but that's not working for some reason. Clockwise turn increases volume, scrolls down, and scrolls right on the Default, Raise, and Alt layers respectively. Counterclockwise does the opposite of the clockwise turns, you get the picture.

+# rainkeeb
+
+![rainkeeb](https://i.imgur.com/GpVBRMw.jpg)
+
+My first custom mech design. 4x10(ish), pro micro based, unibody, split, ortho (any more adjectives?), with OLED and (optional) rotary encoder.
+
+![Default layout](https://i.imgur.com/rCOwsoy.png)
+This is the default layout, at least the base layer. By default the OLED displays "rainkeeb" at the top in case you forget what you're typing on, a layer indicator below that (Default, Raised, Alt), and a WPM counter below that. Encoder toggles Play/Pause on click on the Default and Raised layers, and is supposed to RESET into flash-mode on the Alt layer but that's not working for some reason. Clockwise turn increases volume, scrolls down, and scrolls right on the Default, Raise, and Alt layers respectively. Counterclockwise does the opposite of the clockwise turns, you get the picture.
+
+* Keyboard Maintainer: [rain](https://github.com/rainsff)
+* Hardware Supported: rainkeeb PCB v1
+* Hardware Availability: GB soon
+
+Make example for this keyboard (after setting up your build environment):
+
+    make rainkeebs/rainkeeb:default
+
+To put reset into bootloader mode just push the reset button from the left side of the board using a pair of tweezers or similar object.
+
+Install example for this keyboard:
+
+    make rainkeebs/rainkeeb:default:flash
+
+See the [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) and the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information. Brand new to QMK? Start with our [Complete Newbs Guide](https://docs.qmk.fm/#/newbs).

+# Just60
+
+Just60 keyboard produced by Yang. The keyboard comes with a custom Mass Storage Device bootloader and a TMK based firmware from ydkb.io.
+
+To use a QMK based firmware, you might want to install a QMK bootloader. The PCB exposes 6 pins for ISP(In-System Programming), and they are located just under the ATMega32U4 chip. From left to right, the pins are `VCC`, `SCLK`, `MOSI`, `MISO`, `RESET`, `GND`. The `GND` is the square one. You could program the flash with any AVR programmer, or a Raspberry Pi with `avrdude`.
+
+Backlight LEDs and Bluetooth are not working yet.

- * AVR Boot section size are defined by setting BOOTSZ fuse in fact. Consult with your MCU datasheet.
- * Note that 'Word'(2 bytes) size and address are used in datasheet while TMK uses 'Byte'.
- *
- * Size of Bootloaders in bytes:
- *   Atmel DFU loader(ATmega32U4)   4096

- *   Teensy   halfKay(ATmega32U4)   512
- *   Teensy++ halfKay(AT90USB128)   1024
- *
- * AVR Boot section is located at the end of Flash memory like the followings.
