Im lost

Ok i searched for this so dont get mad at me ;(. But well I don't know how to install codes for ftb1. I got the nitepr working great. I just dont know how to install codes. I tried youtube videos i cant find a tut here. Please do me a favor and just give me a step by step instructions. Thanks To Whoever posts.

1. Open notepad or any word processor.
2. Save as "UCUS-98615.txt" without quotes. UCUS-98615 is the game ID for Socom Fireteam Bravo. Every official game has one.
3 .Place the txt file in the NitePr folder
4. add all codes for that game in the txt file

thanks a bunch hope it works :)
