making a PHPBB2 chat forum?

I want to make a PHPBB2 chat forum for my clan on Jedi Knight 2. I have read the readme and the installation but I am not making any sense out of it. I am provided by angelfire, but if I have to ill go find something else like Geocities or something like that. I use Microsoft Frontpage and I upload my webpage from the web shell on angelfire. I just want to at least know how to make it, but making stuff like background or special pictures I can do later. If someone knows where I could find a MAKING CHAT FORUMS FROM PHPBB2 FOR IDIOTS GUIDE, ide love to see it. Or could someone really go through it and tell me like as though I was only 12 yo. Cause I need a really deep how-to guide. I already have mysql program installed and im pretty sure you need it to make one. I used it to make a 4.4 eqemu server.... so any readme's or idiot guides plz post them here. (im 17 of course)
