+Splitting a commit
+------------------
+
+From [docs](https://git-scm.com/docs/git-rebase#_splitting_commits):
+
+- Start an interactive rebase with `git rebase -i <commit>^`, where `<commit>`
+  is the commit you want to split.
+- Mark the commit you want to split with the action "edit".
+- When it comes to editing that commit, execute `git reset HEAD^`. The effect
+  is that the HEAD is rewound by one, and the index follows suit. However, the
+  working tree stays the same.
+- Now add the changes to the index that you want to have in the first commit
+  (`git add`)
+- Commit the now-current index with whatever commit message is appropriate now.
+- Repeat the last two steps until your working tree is clean.
+- Continue the rebase with `git rebase --continue`.
