+### Conventional Commits
+
+While not currently enforced, by using [conventional commits](https://www.conventionalcommits.org/en/v1.0.0/#summary), it's possible to automatically generate changelogs and version numbers via [release-please](https://github.com/googleapis/release-please).
+
+To help with that, the [commitizen](https://commitizen-tools.github.io/commitizen/) tool can be installed.
+
+#### Usage
+
+```bash
+# install cz
+npm install -g commitizen cz-conventional-changelog
+brew install commitizen
+
+# make repo cz friendly
+commitizen init cz-conventional-changelog --save-dev --save-exact
+npm install
+
+# add file to commit
+git add .gitignore
+
+# run cz
+λ git cz
+cz-cli@4.3.0, cz-conventional-changelog@3.3.0
