+arrow_pad keyboard firmware
+======================
+
+## Quantum MK Firmware
+
+For the full Quantum feature list, see [the parent README.md](/README.md).
+
+## Building
+
+Download or clone the whole firmware and navigate to the keyboard/arrow_pad folder. Once your dev env is setup, you'll be able to type `make` to generate your .hex - you can then use the Teensy Loader to program your .hex file. 
+
+Depending on which keymap you would like to use, you will have to compile slightly differently.
+
+### Default
+To build with the default keymap, simply run `make`.
+
+### Other Keymaps
+Several version of keymap are available in advance but you are recommended to define your favorite layout yourself. To define your own keymap create file named `<name>.c` in the keymaps folder, and see keymap document (you can find in top README.md) and existent keymap files.
+
+To build the firmware binary hex file with a keymap just do `make` with `KEYMAP` option like:
+```
+$ make KEYMAP=[default|jack|<name>]
+```
+Keymaps follow the format **__\<name\>.c__** and are stored in the `keymaps` folder.
