That post you mentioned is the right start. Follow the steps outlined there, and if something's not quite clear just ask.
I'm currently putting a guide together which will be posted on the wiki, every feedback from you users is helpful to me.
For me as a dev who's into that stuff it's the other way round, too many things are obvious to me and I might forget mentioning them. Knowing about these things and what's not really obvious to you will help me creating the guide.
so long,
