-Delete your merged branch (optional)
-------------------------------------
-
-Once your feature branch is accepted into upstream, you'll probably want to get rid of
-the branch. First, merge upstream main into your branch so git knows it is safe to
-delete your branch::
-
-    git fetch upstream
-    git checkout main
-    git merge upstream/main
-
-Then you can do::
-
-    git branch -d shiny-new-feature
-
-Make sure you use a lower-case ``-d``, or else git won't warn you if your feature
-branch has not actually been merged.
-
-The branch will still exist on GitHub, so to delete it there do::
-
-    git push origin --delete shiny-new-feature
