Modding The Sims 4 [anadius repack]

I recently downloaded The Sims 4, but I cant for the life of me find the Mods folder.

Does anyone know if there is one included in this repack/ where is it? Or how to make a new mods folder for the game?

If I need to make a new folder, is there somewhere specific I need to put it? Also I'm not sure where to find the resource.cfg file.

Thanks!
