file based repository

(1)

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

You also need to tell git you have a master branch, and where to pull from. Add these to your .gitconfig:

[branch "master"]
  remote = origin
  merge = refs/heads/master

(2)

rm -Rf myproject
git clone /path/to/sharedfoldername myproject
