For example a typical use-case like git clone http://example.com/my-public-fork git remote add main http://example.com/project-main-repo git pull --set-upstream main master or, instead of the last line git fetch --set-upstream main master git merge # or git rebase This fonctionality works like git push --set-upstream.
