CMS Made Simple Forums

If I understand it right pimenu can do what I want to do. But the problem is I have no idea at all how to use it.  I don't know how to install the files it comes with into my site and I definitely don't know how to adapt them to make a menu. I've tried looking at the translated help file but I know so little about these things even in english I can't make any sense out of it.    I don't know where to start to get it figured out.  It's frustrating because I think if I understood what was going on that it would be easy to do what I want to do with it.
