I want to improve geany's php autocompletion for php functions, adding some extra info and missing functions (also, in my case, some basic drupal function i use quite often).

How can i create my own functions autocompletion suggestion?

I saw the php.tags in /usr/share/geany folder, but looks a bit confusing about syntax.. and does it get ovverride by a php.tags files placed into my ~/.config/geany folder?

Please help, geany is really great and i want to improve it writing more verbose php functions helpers
