Experience with PhpBB?

Who here has experience with the coding of phpBB? Because I am trying to make a new ACP module but I can’t figure out how to do it… I’ll go into more detail on what I’ve done once someone responds.

phpBB have a wiki with all the information you need http://wiki.phpbb.com/Creating_modules

I’m aware of that, but I know I’m not doing something right because I can’t get the module to show up to install…
