I would highly recommend that you start with our "Getting Started" guide. You can find that here: aurelia.io/docs.html
There is also a Pluralsight course by Scott Allen. There are two more Pluralsight courses coming in the next month or two. Three books coming as well.
We're constantly working on our docs. It's a big part of what we're doing in the beta period. If you have trouble getting started or can't find the answers you need, we would invite you to join our gitter chat: gitter.im/aurelia/dicuss.
Also, if you aren't apposed, you can sign up for our mailing list. We aren't evil...promise. I hate junk email. We will use it for major announcements only. durandal.us10.list-manage1.com/subscribe
