 There is basic support for addressable LED matrix lighting with the I2C IS31FL3731 RGB controller. To enable it, add this to your `rules.mk`:
 
-    LED_MATRIX_ENABLE = IS31FL3731
+    LED_MATRIX_ENABLE = yes
+    LED_MATRIX_DRIVER = IS31FL3731
     
 You can use between 1 and 4 IS31FL3731 IC's. Do not specify `LED_DRIVER_ADDR_<N>` defines for IC's that are not present on your keyboard. You can define the following items in `config.h`:
