Hello everybody, Its my first time installing a mod and I got stuck after dowloading a zip file with a mod. I've tried extracting it into the game's folder but didnt work (no file asking to be substitute as for exact name) So how do I proceed from here lads? Am I suppose to download an app to manage all mods? Thanks in advance for reading this! Apologies for typos and if this post broke anyrules
