+# The default ANSI keymap for DC01 Left
+
+The keymap looks like a full layout keymap.
+
+This is because the left part of the keyboard acts as the masterm coordinating all four part.
+
+When using the keyboard to connect the other three parts, this keymap overwrites the individual keymaps of the single modules.
+
+When using a module individually, the keymap of that module will take effect.

+# DC01 Left Half
+
+
+
+A hotpluggable four part keyboard which comes together with magnets and pogo pins! This is the left part that also acts as the master.
+
+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/left: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.
