OpenStack is a big project, and keeping it all running smoothly (or just learning what how to get started) can be a big undertaking. Even if you're a contributor to the project, there's a lot to keep track of, especially with the projects you might be less familiar with. Of course, the official documentation as well as a number of OpenStack training and certification programs can be a big help with learning more, but community-authored tutorials are a great supplement.
