 You need to [create a personal access token](https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/managing-your-personal-access-tokens#creating-a-fine-grained-personal-access-token) and [add it as a secret](https://docs.github.com/en/actions/security-guides/using-secrets-in-github-actions#creating-encrypted-secrets-for-a-repository) named `LIGHTHOUSE_BADGER_TOKEN` to your repository. For more information, check [lighthouse-badger documentation](https://github.com/MyActionWay/lighthouse-badger-workflows#lighthouse-badger-easyyml) on how to do this.

+We implemented support for [Prettier code formatting](https://prettier.io/) in [#2048](https://github.com/alshedivat/al-folio/pull/2048). It basically ensures that your code is well formatted. If you want to ensure your code is compliant with `Prettier` you can install it in your computer [integrated with an editor](https://prettier.io/docs/en/editors), [install it and run manually](https://prettier.io/docs/en/install), or you can disable it for your repo. For this, just delete the file [.github/workflows/prettier.yml](https://github.com/alshedivat/al-folio/blob/master/.github/workflows/prettier.yml).
