This is great. I've been looking for an angular tutorial that leads you through the process of building an application. I learn by doing and the angular tutorial on the official website has way too many 404 links to keep my interest level high. Please continue!
Author here. This article shouldn't be about using Yeoman or not, and if that is what you are getting from the article, I might need to do a better job at writing. As I get further along in 'An Angular Workflow', it will be more about using angular than it is now.
The bootstrap project is a combination of tools, including some ideas taken directly from Yeoman itself. I have it there as a starting point so we can just get to coding.
