Git Upstream
The upstream of a branch is the remote branch it tracks, like origin/main for main. With an upstream set, a plain git pull and git push know where to go, and git status tells you if you are ahead or behind.
In a fork, upstream is also the usual name for a second remote that points to the original repository.
Set the upstream when you push a new branch
A new branch has no upstream yet. Use -u the first time you push it:
git push -u origin html-skeleton
Total 0 (delta 0), reused 0 (delta 0), pack-reused 0 (from 0)
branch 'html-skeleton' set up to track 'origin/html-skeleton'.
