XF 2.0 How to get started with development


Active member
This is about version 2.0

I am searching and searching but I can't really find a manual (or a bunch of tips) on how to:

- set up a page with a php-callback
--- what do I put in the field "Class"
--- what do i put in the field "method"
--- where do I need to put the php-file
--- how can i let this php-file print "hello" on the page

- make an add-on to do something
--- where to start?

Thanks. Help is much appreciated.
