+Lightpad keypad firmware
+======================
+Korean custom keypad designed by Duck.
+
+*Note that this is not the official firmware*
+
+
+Supported models
+----------------
+All pcb options are supported.
+
+
+Build
+-----
+Move to this directory then just run `make` like:
+
+ $ make -f Makefile.lufa
+
+
+Bootloader
+---------
+The PCB is hardwired to run the bootloader if the key at the `top left` position is held down when connecting the keyboard.
+
+It is still possible to use Boot Magic and Command to access the bootloader though.
