Hey revanmg, welcome to the forums
, If your just getting into modding i suggest that you start with a few smaller mods first, as Module editing can be very difficult, i found that out when i wanted to do what you are wanting to do, i went ahead and did it anyway and failed miserably, though now module editing is my specialty.
You should go to the Getting started with modding + List of Tools + downloads
thread to get you started.
There are some tutorials here
that you can read through and see what you want to do.
But just because you asked and I'm nice
there is a Module Creation guide here
, It's a little outdated but it does the job, I'm currently writing an updated Module Creation guide with all the easier ways to do this.
Hope this helped.
