"Put the folders in the THUGPRO data folder and the .prx file in the pre folder.
Disable the internet before launching the game or the updater will remove these files." ~ The readme file.
The readme says everything.
The "code" and "qb" folders go in the "data" folder.
The .prx file goes in the "pre" folder.
If you still don't get it then I don't know how to explain it any other way.
