I feel like an idiot and for someone with an engineering degree that is tough to swallow

I have installed the product, but after reading all the pages here, and every link, I cannot for the life of me understand what you all are talking about. Does ANYONE have a how to use for this? Install it by adding product I got, but then what? Edit what, click where? I see nothing new in my CPAdmin and nothing here to tell me what to do. It is like everyone has experience with vBulletin and expects us new folks to read minds and go to unknown areas. Please post some how to make peanut butter and jelly sandwich directions so we can all expand or knowledge.
Please help
