Interesting (I had never noticed that).
I think we should properly document $resourceProvider instead.

@yilinglu, would you be interested in submitting a PR, properly documenting the $resourceProvider ?

By "properly documenting", I mean adding ngdoc comments (to the provider and its methods/properties), so that $resourceProvider appears in the docs as a separate entry (under ngResource -> provider).
To get an idea of what I am talking about, you can take a look at any other documented provider (e.g. $routeProvider).

OK. I will write it up and submit a PR in the next couple of days.

Awesome, thx !
Feel free to ping me if you need anything (or if you want me to take a look when it's ready).

PR submitted. Please review.
Thanks.

Closing in favor of #11910.
