 ### Code formatting
 
 We use [shellcheck](https://github.com/koalaman/shellcheck) and [shfmt](https://github.com/mvdan/sh) to enforce bash styling guidelines and good practices. They are executed for each commit / PR with GitHub Actions, so you can check the configuration [here](https://github.com/angristan/openvpn-install/blob/master/.github/workflows/push.yml).
