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.
   
   Minor related fixes—such as typos, formatting, preparatory refactoring tightly coupled to a new feature, or immediate bug fixes for issues introduced in the same PR—are acceptable in a single commit if they are logically cohesive and splitting them would reduce clarity or create broken intermediate states.

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
   ```

3. Mercurial is the main VCS.  
   The canonical repo is at https://hg.qwa.su/gbwm  
   GitHub is a read-only mirror - do not send PRs.

   Submit changes as GPG signed patches (e.g. `hg export` output) to <a@qwa.su>.  
   If you want push access to your own namespace on hg.qwa.su, include your public SSH key.
