Start with the first folder "1. Main mod", it contain sounds archive and injector to load the sounds. Open it and put "mods" in your World of tanks folder (default in C:/Progam Files/World_of_Tanks).
If you want to use engine sounds, open the second folder "2. If you want engines sounds" and put "mods" in your World of Tanks folder.
If you want to use gun sounds, open the third folder "3. If you want guns sounds" and put "mods" in your World of Tanks folder.
You can use both engines and guns sounds or just one. That's all folks.
