Overview
Let’s face it, the entire software industry is moving over to git. Open source has already moved. A fairly old, but still interesting, StackOverflow article shows some data on how the open source community has largely moved over to git. You can view the article HERE. The TLDR is this, you need to understand Git.
If your team isn’t already asking for it, they will be shortly. You need to understand what the implications are to your software project, and determine a migration strategy. Also, you need to understand the basic workflow and terminology that Git introduces.
