======================================

Hardware requirement
--------------------
-Arduino Leonardo
+There are two options.
+
+### TMK USB-USB Converter
+You can buy a fully assembled converter from me here.

+
+### Arduino Leonardo + Circuit@Home USB Host Shield 2.0
+Buying Arduino Leonardo and USB Host Shield 2.0(from Circuit@home) will be better, you won't need even soldering iron.

+ https://www.circuitsathome.com/products-page/arduino-shields/usb-host-shield-2-0-for-arduino-assembled/
+
+Other compatible boards like Arduino's Shield will also work well but I think Sparkfun's needs to be modified.
+
+ http://arduino.cc/en/Main/ArduinoUSBHostShield
+ https://www.sparkfun.com/products/9947
+
+Also Pro Micro 3.3V(not Mini) or Teensy with mini host shield will work with some fixes on signal/power routing.

Build firmware
--------------
- $ git clone git://github.com/tmk/tmk_keyboard.git
+Build.
+
+ $ git clone https://github.com/tmk/tmk_keyboard.git
$ cd tmk_keyboard
$ git submodule init
$ git submodule update
$ cd converter/usb_usb
$ make
-You will get usb_usb.hex if you are lucky.
-Program your Leonardo with avrdude(or easy-going Arduino IDE):
+And Program converter. Push button on TMK converter and just run this.
+
+ $ make dfu
+
+
+In case of Leonardo push reset button then run command. Serial port name(COM17) depends your system. On Linux I got /dev/ttyACM0.
+
+ $ DEV=COM17 make program
+ or
+ $ avrdude -patmega32u4 -cavr109 -b57600 -Uflash:w:usb_usb.hex -PCOM17
- $ avrdude -patmega32u4 -cavr109 -PCOM17 -b57600 -Uflash:w:usb_usb.hex
Limitation
----------
Only supports 'HID Boot protocol'.
-Not support keyboard LED yet.
+
+Note that the converter can host only USB "boot protocol" keyboard(6KRO), not NKRO, it is possible to support NKRO keyboard but you will need to write HID report parser for that. Every NKRO keyboard can have different HID report and it is difficult to support all kind of NKRO keyboards in the market.
+
+
+
+Keymap editor
+-------------
+You can editor keymap and download firmware with web brwoser.
