 ## Lighting Layers
 
 By including `#define RGBLIGHT_LAYERS` in your `config.h` file you can enable lighting layers. These make
-it easy to use your underglow LEDs as status indicators to show which keyboard layer is currently active, or the state of caps lock, all without disrupting any animations. [Here's a video](https://youtu.be/uLGE1epbmdY) showing an example of what you can do.

 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
+    {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}
+    {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}, 
+    {11, 2, HSV_PURPLE}
 );
