+## Committing
+
+This project uses [semantic release](https://github.com/semantic-release/semantic-release) to ensure version bumps
+follow semver so that projects depending on it don't break unexpectedly.
+
+In order to automatically determine version updates, semantic release expects commit messages to follow the
+[conventional-changelog](https://github.com/bcoe/conventional-changelog-standard/blob/master/convention.md)
+specification.
+
+You can use the [commitizen CLI](https://github.com/commitizen/cz-cli) to make commits formatted in this way:
+
+```bash
+npm install -g commitizen@latest cz-conventional-changelog@latest
+```
+
+Now you're ready to make commits using `git cz`.
