 This is for building your own physical controller for the game called [K-Shoot Mania](http://kshoot.client.jp) with an Arduino Uno as a USB interface.
 
-Previous alternatives are connecting buttons to disassembled [Joystick circuit](http://homingpuyo.blog91.fc2.com/blog-entry-650.html), or using an [Arduino Leonardo](http://sdvxii.pancakeapps.com/LEONARDO). Arduino Uno cannot interface as a keyboard as easily as Leonardo. Only [Leonardo, Micro, and Due](https://www.arduino.cc/en/Reference/MouseKeyboard) can use the built-in keyboard function.

 ##Requires
-- A firmware flash hack that will make your Arduino HID compatible but loses ability to program. (Need to flash the firmware back to reprogram) (Cannot brick your Uno.)

-Please wait after I tested the code more.
+Please wait for more information after I tested the code more. But if you want to go ahead here are rough steps :
+- Make a controller.
+- Look at the code's top part and config things according to your connections to Uno's pin. Please read the comments. (Important)
+- Upload the code to your Uno with the [Arduino IDE](https://www.arduino.cc/en/Main/Software).
+- Do the [firmware flash hack](http://mitchtech.net/arduino-usb-hid-keyboard/).
+- Reconnect and done!
