MyBB Community Forums

Good day,
I just installed MyBB forum and want to start creating my own theme, but i don't know were to start. First i want to say that i have html/css and some php knowledge and experiance in wordpress theme editing, but this forum themes is nothing like that. First i was looking at some tutorials or documentation but i couldn't find any good information. Can some one help me get started?

See [wiki]Admin_CP_Themes#Create_New_Theme[/wiki]

And how about adding something like JavaScripts, adding some php code or removing?
P.s i said that i know css

You cannot use PHP in templates, as that's a security risk.

To add javascript, add the reference to the 'headerinclude' template under 'Ungrouped Templates'.

Thx i have some idea how things works here.
