Angular plus the WordPress REST API

More and more examples are popping up of the WordPress REST API and other platforms playing together. Michael Bromley has a post and source code for how he built his blog with AngularJS and the WordPress REST API.

I really can't get enough of these examples, but I also am seeking advice for where to start. Finished projects are good, but for many, a step by step series on {technology} + the WordPress REST API would be really useful.
