 - `SONAR_TOKEN` – **Required** this is the token used to authenticate access to SonarQube. You can read more about security tokens [here](https://docs.sonarqube.org/latest/user-guide/user-token/). You can set the `SONAR_TOKEN` environment variable in the "Secrets" settings page of your repository, or you can add them at the level of your GitHub organization (recommended).
 
+- `SONAR_HOST_URL` – **Optional** this tells the scanner where SonarQube is hosted, otherwise it will get the one from the scan report. You can set the `SONAR_HOST_URL` environment variable in the "Secrets" settings page of your repository, or you can add them at the level of your GitHub organization (recommended).
