Search, search, search as dumdum says the interweb has the answer if you just look. Welcome to the club! And choose your mod path wisely. Don't jump into something your not ready for or you will regret it later. Remember your not pioneering new ground here at all someone here has already done it. As far as a first mod goes go with some sort of em and build from there.
