+NerD keyboard firmware
+========================
+
+Korean Keyboard designed by GON.
+
+*Note that this is not the official firmware*
+
+
+Hardware revision
+-----------------
+
+This firmware was developed and tested for NerD pcb version 1.61 and 2.0.
+
+
+Supported features
+------------------
+
+* All layout options are supported
+* All leds are supported
+
+
+Changing Bootloader
+-------------------
+
+You can't simply just upload this firmware to a new NerD board because the original
+bootloader won't accept DFU connections.
+
+You can change the bootloader of the keyboard with an ISP programmer of your choice.
+The bootloader pins are easy to access on the NerD pcb.
+
+*Be aware that after changing the bootloader the official configuration software
+won't work anymore and you'll lose your warrenty. GON won't provide any support for this firmware.*
+
+
+Build
+-----
+
+Move to this directory then just run `make`.
+
+
+Jump to Bootloader
+------------------
+
+You can jump to bootloader by software if you have a macro defined for this in your keymap. The
+default command is (LSFT+RSFT+PAUS) to access the bootloader by software jump.
