multiple users with a public repository

start a new project or change to an existing project

initialize a personal git repo

clone this repo to a bare repo, and move it to a public place

	git clone --bare /path/to/myproject sharedfoldername

either (1) set the public repo up as a remote in the personal repo, or (2) remove the original project directory, and clone the new bare repository

(1)
git remote add origin /Volumes/Seagate-1/gitbackup/Autofill/

(2)
rm -Rf myproject
git clone /path/to/sharedfoldername myproject

now use git fetch, git merge, and/or git pull
