Understanding the manual - how to change the heading
 

I'm trying to finsd out if vBulletin does what I need. Its forum facilities are very good, but I need to integrate it neatly (or rather make it look integrated) with a main static website. So I need a heading there all the time, with a navigation bar and links to parts of the other website. The Forum link would of course be to the vBulletin site.

I've just tried reading through the manual and it isn't easy to understand how I can do this - I'm sure it can do it, but where is it described please?

At the moment I can't even figure out how to replace the graphic saying vBulletin at top left? Let alone how to add the HTML with the navigation bar.

I'd be grateful if you could point me to where in the manual this is covered. I think part of the problem is that I don't yet know enough to understand all of the manual.

Thank you.
