 * Keyboard Maintainer: QMK Community
-* Hardware Supported: YD60MQ PCB, ATmega32U4
+* Hardware Supported: YD60MQ PCB
+    * 12led (unknown revision number, has 12 RGB LEDs on the back) – _default variant_

 Make example for this keyboard (after setting up your build environment):
 
-    make yd60mq:default
+```sh
+make yd60mq:default        # builds the 12 LED variant
+make yd60mq/12led:default  # also builds the 12 LED variant
+make yd60mq/16led:default  # builds the 16 LED variant
+```
 
 The keyboard uses a DFU bootloader. To make a keymap and use dfu to flash it:
 
-    make yd60mq:default:flash
+```sh
+make yd60mq:default:flash        # builds and flashes the 12 LED variant
+make yd60mq/12led:default:flash  # also builds and flashes the 12 LED variant
+make yd60mq/16led:default:flash  # builds and flashes the 16 LED variant
+```
