base: mine 
head fork: original

Change repo remote url from http to ssh

change url in .git/config from:

https://github.com/USERNAME/OTHERREPOSITORY.git

to

git@github.com:USERNAME/OTHERREPOSITORY.git

Having already cloned the repo, but not forked it

  • Ideally, create the repo with: https://developer.github.com/v3/repos/#create
  • If not, create it via forking the repo.
  • In this example, it will be https://github.com/JAremko/alpine-vim
  • Forking it will result in https://github.com/octosh/alpine-vim
  • In your local, add a new remote to your fork; then fetch it, and push your changes up to it
    git remote add my-fork https://github.com/octosh/alpine-vim
    git fetch my-fork
    git push my-fork master

Traditionally

Otherwise, if you want to follow convention:

  1. Fork their repo on Github

  2. In your local, rename your origin remote to upstream

    git remote rename origin upstream

  3. Add a new origin

    git remote add origin git@github...my-fork

  4. Fetch & push

    git fetch origin git push origin
