What should go here, as opposed to webdev.dartlang.org/angular?
Eventually this page will have guidelines on what goes where. (Is there a better place for this?)
Please comment on https://github.com/dart-lang/site-webdev/issues/471.
Background: There are plenty of docs at (aka angulardart.org), and that site is publicly editable at https://github.com/dart-lang/site-webdev. However, the process for creating a new page is much more heavyweight than here.
