It’s important to know how to revert a commit, because sometimes you accidentally commit strait to master.

If you caught yourself before pushing upstream, you’re good. Just

git checkout -b temporary
git branch -D master
git checkout master

This assuming it automatically pulls master back down from upstream, which is my default setup.

If you did push upstream, you’ll basically want to create a commit that reverts the latest commit. Hopefully it’s only one commit.

git format-patch -1 HEAD
git apply [newly_created_patch_name] -R
