+GH60 keyboard firmware
+======================
+DIY compact keyboard designed and run by komar007 and Geekhack community.
+
+- Both Rev.A and Rev.B PCB are supported by one firmware binary(issue #64)
+
+## GH60 Resources
+- [KOMAR's project page](http://blog.komar.be/projects/gh60-programmable-keyboard/)
+- [Prototyping](http://geekhack.org/index.php?topic=34959.0)
+- [Rev.A PCB test](http://geekhack.org/index.php?topic=37570.0)
+- [Rev.B PCB test](http://geekhack.org/index.php?topic=50685.0)
+- [Group buy](http://geekhack.org/index.php?topic=41464.0)
+
+
+## Build
+Move to this directory then just run `make` like:
+
+    $ make
+
+Use `make -f Makefile.pjrc` if you want to use PJRC stack but I find no reason to do so now.
+
+
+## Keymap
+Several version of keymap are available in advance but you are recommended to define your favorite layout yourself. To define your own keymap create file named `keymap_<name>.c` and see keymap document(you can find in top README.md) and existent keymap files.
+
+To build firmware binary hex file with a certain keymap just do `make` with `KEYMAP` option like:
+
+    $ make KEYMAP=[poker|poker_set|poker_bit|plain|hasu|spacefn|hhkb|<name>]
+
+
+### 1  Poker
+[keymap_poker.c](keymap_poker.c) emulates original Poker layers
+while both [keymap_poker_bit.c](keymap_poker_bit.c) and [keymap_poker_set.c](keymap_poker_set.c) implements same layout in different way and they fix a minor issue of original Poker and enhance arrow keys.

+This is my favorite keymap with HHKB Fn, Vi cursor and Mousekey layer. See [keymap_hasu.c](keymap_hasu.c) for detail.
+
+
+### 4. SpaceFN
+This layout proposed by spiceBar uses space bar to change layer with using Dual role key technique. See [keymap_spacefn.c](keymap_spacefn.c) and [SpaceFN discussion](http://geekhack.org/index.php?topic=51069.0).
