 ### Environment variables
 
 - `SONAR_TOKEN` – **Required** this is the token used to authenticate access to SonarQube. You can read more about security tokens in the documentation of SonarQube [Server](https://docs.sonarsource.com/sonarqube-server/latest/user-guide/managing-tokens/) and [Cloud](https://docs.sonarsource.com/sonarqube-cloud/managing-your-account/managing-tokens/). 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).
-- *`GITHUB_TOKEN` – Provided by Github (see [Authenticating with the GITHUB_TOKEN](https://help.github.com/en/actions/automating-your-workflow-with-github-actions/authenticating-with-the-github_token)).*
 - `SONAR_HOST_URL` – this tells the scanner where SonarQube Server is hosted. You can set the `SONAR_HOST_URL` environment variable in the "Variables" settings page of your repository, or you can add them at the level of your GitHub organization (recommended). Not needed for SonarQube Cloud.
 - `SONAR_ROOT_CERT` – Holds an additional certificate (in PEM format) that is used to validate the certificate of SonarQube Server or of a secured proxy to SonarQube (Server or Cloud). You can set the `SONAR_ROOT_CERT` environment variable in the "Secrets" settings page of your repository, or you can add them at the level of your GitHub organization (recommended).
