lutinut

Ok so I understand there is a tutorial on how to do it but knowing how to do it and doing it are two different things. My computer just isn't equiped for this kind of thing but it lets me download and play modpacks so i was wondering if someone could help me. All I want is a LOTR modpackpack that is up to date with battle gear, custom npcs, minecraft comes alive, and a few other mods that would go good with it. Will someone please help?
