I have put together an Orac tutorial in the past that you can find here in this forum post. I am planning on redoing it soon since I feel like I could have explained things better but maybe it will help things click for you
I’m almost done with written documentation which I think will probably serve a lot better rather then me trying to film a tutorial with only a couple takes. It has details on all of the stock modules, the different types of modules, and a couple of typical use cases
