At minimum you must define the data pin your LED strip is connected to, and the number of LEDs in the strip, in your `config.h`. If your keyboard has onboard RGB LEDs, and you are simply creating a keymap, you usually won't need to modify these.
-|Define |Description |
-|------------|---------------------------------------------|
-|`RGB_DI_PIN`|The pin connected to the data pin of the LEDs|
-|`RGBLED_NUM`|The number of LEDs connected |
+|Define |Description |
+|---------------|---------------------------------------------------------------------------------------------------------|
+|`RGB_DI_PIN` |The pin connected to the data pin of the LEDs |
+|`RGBLED_NUM` |The number of LEDs connected |
+|`RGBLED_SPLIT` |(Optional) For split keyboards, the number of LEDs connected on each half directly wired to `RGB_DI_PIN` |
Then you should be able to use the keycodes below to change the RGB lighting to your liking.
You can also modify the speeds that the different modes animate at:
+Here is a quick demo on Youtube (with NPKC KC60) (https://www.youtube.com/watch?v=VKrpPAHlisY).
+
```c
// How long (in milliseconds) to wait between animation steps for each of the "Solid color breathing" animations
const uint8_t RGBLED_BREATHING_INTERVALS[] PROGMEM = {30, 20, 10, 5};
If you need to change your RGB lighting in code, for example in a macro to change the color whenever you switch layers, QMK provides a set of functions to assist you.

Additionally, [`rgblight_list.h`](https://github.com/qmk/qmk_firmware/blob/master/quantum/rgblight_list.h) defines several predefined shortcuts for various colors. Feel free to add to this list!
-## Hardware Modification
+## Changing the order of the LEDs
+
+If you want to make the logical order of LEDs different from the electrical connection order, you can do this by defining the `RGBLIGHT_LED_MAP` macro in your `config.h`.
+
+Normally, the contents of the LED buffer are output to the LEDs in the same order.
+<img src="https://user-images.githubusercontent.com/2170248/55743718-01866c80-5a6e-11e9-8134-25419928327a.JPG" alt="simple dicrect" width="50%"/>
+
+By defining `RGBLIGHT_LED_MAP` as in the example below, you can specify the LED with addressing in reverse order of the electrical connection order.
+
+```c
+// config.h
+
+#define RGBLED_NUM 4
+#define RGBLIGHT_LED_MAP { 3, 2, 1, 0 }
+
+```
+<img src="https://user-images.githubusercontent.com/2170248/55743725-08ad7a80-5a6e-11e9-83ed-126a2b0209fc.JPG" alt="simple mapped" width="50%"/>
+
+For keyboards that use the RGB LEDs as a backlight for each key, you can also define it as in the example below.
+
+```c
+// config.h
+
+#define RGBLED_NUM 30
+
+/* RGB LED Conversion macro from physical array to electric array */
+#define LED_LAYOUT( \
+ L00, L01, L02, L03, L04, L05, \
+ L10, L11, L12, L13, L14, L15, \
+ L20, L21, L22, L23, L24, L25, \
+ L30, L31, L32, L33, L34, L35, \
+ L40, L41, L42, L43, L44, L45 ) \
+ { \
+ L05, L04, L03, L02, L01, L00, \
+ L10, L11, L12, L13, L14, L15, \
+ L25, L24, L23, L22, L21, L20, \
+ L30, L31, L32, L33, L34, L35, \
+ L46, L45, L44, L43, L42, L41 \
+ }
+
+/* RGB LED logical order map */
+/* Top->Bottom, Right->Left */
+#define RGBLIGHT_LED_MAP LED_LAYOUT( \
+ 25, 20, 15, 10, 5, 0, \
+ 26, 21, 16, 11, 6, 1, \
+ 27, 22, 17, 12, 7, 2, \
+ 28, 23, 18, 13, 8, 3, \
+ 29, 24, 19, 14, 9, 4 )
+
+```
+## Clipping Range
+
+Using the `rgblight_set_clipping_range()` function, you can prepare more buffers than the actual number of LEDs, and output some of the buffers to the LEDs. This is useful if you want the split keyboard to treat left and right LEDs as logically contiguous.
+
+You can set the Clipping Range by executing the following code.
+
+```c
+// some soruce
+ rgblight_set_clipping_range(3, 4);
+```
+<img src="https://user-images.githubusercontent.com/2170248/55743785-2bd82a00-5a6e-11e9-9d4b-1b4ffaf4932b.JPG" alt="clip direct" width="70%"/>
+
+In addition to setting the Clipping Range, you can use `RGBLIGHT_LED_MAP` together.
+
+```c
+// config.h
+#define RGBLED_NUM 8
+#define RGBLIGHT_LED_MAP { 7, 6, 5, 4, 3, 2, 1, 0 }
+
+// some soruce
+ rgblight_set_clipping_range(3, 4);
+```
+<img src="https://user-images.githubusercontent.com/2170248/55743747-119e4c00-5a6e-11e9-91e5-013203ffae8a.JPG" alt="clip mapped" width="70%"/>
If your keyboard lacks onboard underglow LEDs, you may often be able to solder on an RGB LED strip yourself. You will need to find an unused pin to wire to the data pin of your LED strip. Some keyboards may break out unused pins from the MCU to make soldering easier. The other two pins, VCC and GND, must also be connected to the appropriate power pins.
