+# DC01 Right Half
+
+![DC01 Right Half](https://i.imgur.com/PTn0sp8.jpg)
+
+A hotpluggable four part keyboard which comes together with magnets and pogo pins! This is the right part
+
+Keyboard Maintainer: [Yiancar](https://github.com/yiancar)  
+Hardware Supported: Runs on an atmega32u4  
+Hardware Availability: [Mechboards](https://mechboards.co.uk/)  
+
+Make example for this keyboard (after setting up your build environment):
+
+    make dc01/right:default
+
+See [build environment setup](https://docs.qmk.fm/build_environment_setup.html) then the [make instructions](https://docs.qmk.fm/make_instructions.html) for more information.
