Is there a centralised 'modding vB' guide/document/resource?

[geebusUK]

Hi,
New here.

I'm looking to do some mods to a moderately sized vB system a friend runs.

Initially I was planning to just hack it, but thought it'd be nice if I can do it all 'properly', with plugins/a product.

I've been searching and reading the various guides etc on here, but having had no experience with vB before it's a bit confusing consolidating all this information into useful knowledge.

So, is there any centralised resource going through the basics of modding vB?
Even just some documents explaining the basics of what to use when would be a good start.
