 We use [python-semantic-release](https://python-semantic-release.readthedocs.io/en/latest/) to generate patch releases
 from commits to the `main` branch.
 
+For example, to perform a "patch" release, add a commit to `main` with a comment like:
+
+```
+fix: Resolve vulnerability: CVE-2020-27783 in lxml
+```
+
 To avoid performing a release after a commit to the `main` branch, be sure your commit message includes `[skip ci] `.
