Working with a new client, with poor previous documentation, I found a .git folder in their site files. But when I check for a git install via terminal with `git --version` I get "command not found", so I reason git is not installed.

Any ideas what this might mean? For example, how was the .git folder created? Is there a GUI that uses .git without a terminal git version?

**Update:**
Copied files over to my local machine (that has git) and ran `git remote show origin` to try and back-trace what they were doing before. But I get the following message: `fatal: Not a git repository (or any of the parent directories): .git`

I've checked questions and answers at the following and they aren't applicable :
