+## ZMK Firmware adapted for duckboard/nice!nano combo
+
+Last Updated: 31 Dec 2020
+
+**_warning:_** this is beta firmware that is in its very early stages, many functions still need to be tested
+
+Please message me on [discord](https://discord.gg/K3SJrtN5PJ) if you find any bugs
+
+Credit for the ZMK Firmware to [The ZMK Contributors](https://zmkfirmware.dev/)  
+Hardware credit for the duckboard to [doodboard](https://doodboard.xyz/)  
+Hardware credit for the nice!nano to Nicell of [nice keyboards](https://nicekeyboards.com/)  
+
+Join the [ZMK Discord Server](https://zmkfirmware.dev/community/discord/invite) and the [doodboard Discord Server](https://discord.gg/UCEnxWk)
+
+Flashing Instructions:
+*download the duck.uf2 file
+*plug in the nice!nano to your computer and put it in bootloader (short gnd+rst twice)
+*the nano should appear as a storage device on your computer once in bootloader mode
+*drag the duck.uf2 file into the nano storage and it should flash automatically
+
+further flashing instructions in the [nice!nano docs](https://docs.nicekeyboards.com/#/nice!nano/getting_started?id=flashing-firmware-and-bootloaders) 
+
+*Default Layout:*
+
+| Layer 0 (Default) | Layer 1 (Function) | Layer 2 (RGB and BT) |
+  ------  | ------ | ------
