GitLab Under the Hood

This is a reference for those who are interested in how GitLab works under the hood and how things are linked together.

GitLab is first and foremost a Ruby on Rails project. So some familiarity with both Ruby and Rails are essential. But for GitLab to do what you expect it to do, a few extra pieces are necessary beyond Rails and a database. The following topics are meant to help you understand GitLab in the areas which go beyond what you would find in a "normal" Rails project.
