And of course we can't not mention the tutorials on this website:
The index covers everything in OP's program and each section has snippets of running code as demonstration. It is up there with the best, if not the best, for new starters especially.
The reference section is a good place too!

I don't believe that it's not the case that we can't not mention not to forgo the reading (or not) of the tutorials. Not.
