-Preonic keyboard firmware
-======================
-DIY/Assembled compact ortholinear 50% keyboard by [Ortholinear Keyboards](http://ortholinearkeyboards.com).
-
-## 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 keyboards/preonic folder. Once your dev env is setup, you'll be able to type `make` to generate your .hex - you can then use `make dfu` to program your PCB once you hit the reset button. 
-
-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 a file in the keymaps folder named `<name>.c` 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.
