+There is basic support for addressable RGB matrix lighting with a WS2811/WS2812{a,b,c} addressable LED strand. To enable it, add this to your `rules.mk`:
+
+```C
+RGB_MATRIX_ENABLE = WS2812
+```
+
+Configure the hardware via your `config.h`:
+
+```C
+// The pin connected to the data pin of the LEDs
+#define RGB_DI_PIN D7
+// The number of LEDs connected
+#define DRIVER_LED_TOTAL 70
+```
+
+---
+
 From this point forward the configuration is the same for all the drivers.
