+
+Forces an update of the remote branch adter rewriting the history locally.
+
+- Use `git push -f` to force update the remote branch, overwriting it using the local branch's changes.
+- This operation is necessary anytime your local and remote repository diverge.
+
+```sh
+git push -f
+```
+
+```sh
+git checkout patch-1
+git pull
+git rebase master
+# Local `patch-1` branch has been rebased onto `master`, thus diverging
+# from the remote `patch-1` branch
+
+git push -f # Force update the remote `patch-1` branch
+```
