title: IntelliJ IDEA doesn't recognize that my project is in git, has "N/A" for branch name
body: <p>I am expanding on work done by another developer, and was given their existing code base over sneakernet. I started working on my local machine before the Git repository for the project was set up. Now, after getting access to the repository, I've cloned the repository to my local machine, set up my feature branch, added my changes to that directory, and have pushed my changes to the origin.</p>
  
  <p>However, when I switched back to IntelliJ IDEA to continue working, it doesn't recognize that the project is now using Git. Where I would normally expect to see my branch name, it just says "N/A". How do I get IntelliJ to recognize that my project is a Git project now?</p>
