Git Standards

Git standards Creative Commons License

Git is the democracy of programming: it is the worst tool for version control, except all those other tools that have been tried from time to time. Among other problems, Git’s command names are obtuse (what is a “rebase”?) and non-orthogonal (how is “resetting” different than “checking out”?), and Git generally impedes the creation of an accurate mental model, but without understanding its underlying directed acyclic graph, one can’t move from beginner to intermediate user. Still, it is a necessary tool in every developer’s toolbox, and following good Git practices leads to smoother, more productive development. This guide assumes you already know how to use Git and discusses some of the higher level issues around standards for collaboration.
