Help installing mods

Please don't combine this with the mega thread. That thread is just people complaining. I need assistance understanding how these things work. I don't understand where to equip what.

Can anyone explain how these things should be installed? I don't understand. The tutorial was worthless. A friend of mine played summoners war and says these are an exact copy of mods there. However I've never played summoners war. Anyway, can anyone help explain the installation of these things?
