where do I find a complete openframework documentation?

the site’s documentation only shows the functions but does not describe what it means and what each one does.

There is a ofBook

Also a copy of “Mastering openframeworks, creative coding demystified” by Denis Perevalov is well worth its price.

By the way the examples (in the “examples” dir) are invaluable, and it is often a good idea to peek the OF source code as there are lots of helpful comments in it.
