Which forum software has the best manual?

Which forum software has the most comprehensive manual, that allows Admins to get to grips with and fully understand how to admin a forum running on that software?

I've never used a forum manual when running a software I'm not familiar with. I'm the kind of person who likes to experiment and try to figure out what to do, how to do it, etc, on my own. But that's just me though.

In my experience, vBulletin has the best user manual with their product.

Thanks for your opinions. Anyone else?
