 ### Turning LEDS on
 To turn the LEDs on, you have to edit the `rules.mk` file. If you use the default layout, it can be found here `keyboards/crkbd/keymaps/default/rules.mk`. Add the following line to the top of the file:
 ```
-RGBLIGHT_ENABLED = yes
+RGBLIGHT_ENABLE = yes
 ```
 
 Compile and flash to both sides and all LEDs should turn on and __glow red__ if you have soldered everything correctly. If you run the default firmware and the LEDs turn a differrent color, the data to the LEDs is probably corrupted somewhere along the way. Check the LED before the first one turning a different color using the troubleshooting guide below.
