+
+The [`CHANGELOG.md`](./CHANGELOG.md) and release page uses **commit message
+prefixes** for grouping and highlighting. A commit message that
+starts with `[prefix:] ` will place this commit under the respective
+section in the `CHANGELOG`.

+- `fix:` - Use for bug fixes
+- `docs:` - Use for changes to the documentation
+- `kaizen:` - Use for improvements, including optimization and new features
+

+is recommended to break up your commits using distinct prefixes.
