Inside the folder you should see another folder and inside it yet another folder. You should now see 3 things inside the Mod's folder, 2 files and 1 folder. Unzip the Mod and put its folder in there. There create a folder named "Mods" (without the quotes). Once that's done you need to go to your AppData folder (I'm assuming you're on Windows btw) and then you should locate the game's "hidden" folders: through LocalLow -> AtomTeam -> Atom. So the first thing you need to do is go here and download the Mod.

And although the Devs did gave all the resources for it they haven't done much in the instructions department, so.here you go, comrades. No one seems to have done it yet and personally I think it's a very cool feature to have.
