V-USB and arduino environment

Hello,

recently I've seen a V-USB web page which enable simple non USB avr chips to have USB communication with PC and imitate HID devices. I'm interested in keyboard.

I can't get how to include files which are downloadable from their web page in my project.

  1. my main task is to upload code on atmega328 using Arduino Uno.
  2. then take atmega328 chip on the breadboard and connect to PC
  3. make chip act like HID (keyboard)

my main misunderstood is that I can't get how to upload this files on atmega chip and make it work
please help me, it would be very helpful for me.

I'm pretty sure that you'll have answer on my question.
please just answer me. I need to do this very much.

There is an Arduino port for the library
