Making vbulletin plugins

[ZiG]

Are there any good resourced or tutorials for learning how to make vBulletin plugins and modifications? I've never really run into any documentation on this and I'd like to learn how.

There is a simple documentation in the vBulletin User Manual here.

Plugins basically let you insert code wherever there is a "$hook" variable in a file.
You will need PHP knowledge.

There are plenty of articles/threads about it, if you do a search you should find plenty of results.
