Angular 1.4.5 -- pre-Angular-2 resources

I was learning the latest Angular (4+). Then I got a job working on an Angular 1.x app. I have compiled a fairly healthy stack of documentation to go through. Coupling that with the official documentation and existing code that I can reference on the project, I am off to a very solid start. However, I thought it worth bringing up here in case any one had pointers / links.

Thanks!
