 1. Supply power with VCC and GND.
 2. Connect CLOCK to PD1 and DATA to PD0. You can change pin with config.h.
 3. Optionally you may need pull-up register. 1KOhm probably work.

 Build Firmware
 --------------
 Just run `make`:
 
-    $ make
+    $ make -f <makefile>
+
+For TMK Converter rev.1 use `Makefile.tmk_rev1` as makefile:
+
+    $ make -f Makefile.tmk_rev1
+
+For TMK Converter rev.2 use `Makefile.tmk_rev2` as makefile:
+
+    $ make -f Makefile.tmk_rev2
 
 To select keymap:
 
-    $ make KEYMAP=[plain|...]
