 Build Firmware
 --------------
-Just use 'make'
+For TMK converter with ATmega32U2 just run `make` to build firmware hex file.
+For other DIY converters with ATmega32U4 like Teensy2 or Pro Micro use `make -f Makefile.atmega32u4` instead of `make`.
 
     $ cd sun_usb
     $ make
 
-Then, load the binary to MCU with your favorite programmer.
+Then, load the hex file into MCU with your favorite programmer. If you have `dfu-programmer` installed you can use `make dfu`.

+    $ make dfu
