-# DC01 Arrow Cluster
-
-![DC01 Arrow Cluster](https://i.imgur.com/PTn0sp8.jpg)
-
-A hotpluggable four part keyboard which comes together with magnets and pogo pins! This is the arrow cluster.
-
-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/arrow:default
-
-See [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) then the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information.
