 ### Build one yourself using 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.

 Other compatible boards like Arduino's Shield will also work well but I think Sparkfun's needs to be modified.

 Also Pro Micro 3.3V(not Mini) or Teensy with mini host shield will work with some fixes on signal/power routing.

+# narze's layout for usb-usb converter

+## Key features
+- Qwerty + [Colemak](https://colemak.com) layouts, and you can type Qwerty on software-level Colemak as well. Very useful for gaming or when your friend wanna type something but don't use Colemak.
+- [(S)uper (D)uper Mode](https://github.com/jasonrudolph/keyboard#super-duper-mode) inspired by [jasonrudolph](https://github.com/jasonrudolph), with [some extensions](https://gist.github.com/narze/861e2167784842d38771) such as backspace & forward delete.
+
+## Build instructions
+- `cd /path/to/qmk_firmware`
+- Ensure latest libraries are loaded `make git-submodule`
+- Build & flash : `make converter/usb_usb:narze:flash`
