Background[edit]
Introduction[edit]
Source control enables us to track and manage changes to our code. This functionality becomes increasingly critical as the size of our projects grows both in terms of the lines of code and the number of coders. Source control shows us who changed the code and when. We're able to compare one revision of code to another. And, when necessary, we can rollback changes to a previous revision.
Git[edit]
There are many options to choose from when selecting a source control system. We'll be using one called git, created by Linus Torvalds in 2005. It's a distributed version-control system, meaning that every Git directory on every computer is a repository with a complete history and full version-tracking abilities.
