Dominate unruly files with the Git technique
You have a folder with some files in. Right now you have no way of finding out what those files contained yesterday, or which of them is the latest version of that doc you've been emailing back and forth with those other change makers. If you are really, really disciplined, there is a tiny chance that you won't lose something important, at some point. But no matter what delusions you may have picked up, you are, like the rest of us, fallible, so chances are you already did.
Lets discipline these unruly files with the wonder of version control. Bring out the git.
The first step is to run git on your local project directory, turning it into a local git repository.
