 ## Adding Token for Lighthouse Badger
 
 To add secrets for [lighthouse-badger](https://github.com/alshedivat/al-folio/actions/workflows/lighthouse-badger.yml), create a [personal access token (PAT)](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. The [lighthouse-badger documentation](https://github.com/MyActionWay/lighthouse-badger-workflows#lighthouse-badger-easyyml) specifies using an environment variable, but using it as a secret is more secure and appropriate for a PAT.
