 ## Introduction
 
 This package is a rules preset package for [https://commitlint.js.org/](https://commitlint.js.org/).
+
+## Formatters
+
+We provide some custom formatters under the `formatters` folder. Run these by providing the `--formatter` argument to commitlint like as follows;
+
+```sh
+npx commitlint --format @tablecheck/commitlint-config/formatters/junit
+```
