+- **Contributors.** Anyone contributing content to a given document, with no special privileges. They cannot contribute directly to `master` branch, so they have to contribute pushing branches and issuing a _merge request_ (i.e. requesting their intergration).
+- **Editor/Reviewer**. The person (or people) in charge of integrating (_merging_) contributions into the main document. In consequence, they can push changes directly to the `master` branch.
