Frequently Asked Questions

How do I work with a bare repository?

A bare repository only consists of the history and is not intended to be used directly. If you want to work on a specific repository you must first convert it into a non-bare Git repository. That will give you the working tree of a specific branch.

Execute the following to clone the bare Git repository .\my_project.git into a non-bare Git repository .\my_project:

git clone .\my_project.git
