+If gbwm ever gets contributors, here's a short memo with the rules:
+
+1. Do not combine multiple unrelated changes in a single commit.
+   If your commit touches several independent features or fixes and isn't logically atomic, split it.
+
+2. Use natural-language commit prefixes.
+   Examples of valid prefixes:
+   - feat, feature, featured — for small useful improvements
+   - add, added — for new functionality
+   - del, deleted, removed — for removed functionality
+   - refactor, refactored — for code improvements that don't change behavior
+
+   Good commit messages look like:
+   ```
+   featured useful keybindings for laptop users
+   XF86 keybindings fix
+   added remembering for last focused window
+   feat: moved config out of the main file
+   ```
