Does anyone know where I can learn more about CI in general? A good article/book?

CircleCI looks great.

I'd advise against trying to learn "about" CI. There are articles and even books about CI, and they over complicate it I feel. The way I would think about is simple: each time you push code, tests run. That's all there is to it :)

And thanks!
