+GON NerD keyboard firmware
+======================
+
+## Changing Bootloader
+
+It's not possible to simply flash this firmware on the GON NerD keyboard as the original bootloader does not support DFU connections.
+
+It is possible to change the bootloader of the GON NerD with an ISP programmer. A guide on how to change the bootloader on your GON NerD can be found here:
+[Converting NerD60 to TMK](https://deskthority.net/wiki/Converting_NerD60_to_TMK). After changing the bootloader you can flash your QMK keymap onto the keyboard.
+
+_After changing the bootloader on your GON NerD PCB you will not be able to go back to the original firmware and the official configuration software will
+not work anymore. You will lose your warranty and official support from GON!_
+
+## Reset button
+
+To run the `make dfu` command to flash keymaps onto the board, you need to put the board into DFU mode. As the GON NerD PCBs do not have a reset button on the board to put it into DFU mode, be sure to include a `RESET` button on your keymap. Otherwise you'll have to unscrew your keyboard from the case and short the GND and RST pins.
+
+## Building
+
+Download or clone the whole firmware and navigate to the keyboards/gonnerd 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 default`.
+
+### 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 folder with the name of your keymap in the keymaps folder, and see keymap documentation (you can find in top readme.md) and existant keymap files.
+
+To build the firmware binary hex file with a keymap just do `make` with a keymap like this:
+
+```
+$ make [default|jack|<name>]
+```
+
+Keymaps follow the format **__\<name\>.c__** and are stored in the `keymaps` folder.
