Hi [USER] - thank you for this clear explanation of you problems with finding documentation on how to integrate Angular with Firebase.

As you say there is https://github.com/angular/angularfire which has quite good docs. I am not sure what your concerns are about that library. It is probably the most up to date resource on such an integration.

Regarding the Angular team documenting this integration directly, I'm afraid that is not going to happen. There are lots of potential backends out there that can be accessed via Angular apps and it is beyond our ability to document them all. I would recommend using AngularFire and filing issues or feature requests with them if there are areas that do not work as you wish.
