# convert "bare" git repo to a "normal"  by doing the following:
Make a .git folder in the top-level of your repository.
Move the repository management things  into the .git you just created.
git config --local --bool core.bare false - to convert the local git-repository to non-bare.
checkout master, or do a git reset --hard, and you are done.
