-# This workflow uses actions that are not certified by GitHub.
-# They are provided by a third-party and are governed by
-# separate terms of service, privacy policy, and support
-# documentation.
-
-# This workflow helps you trigger a SonarQube analysis of your code and populates
-# GitHub Code Scanning alerts with the vulnerabilities found.
-# (this feature is available starting from SonarQube 9.7, Developer Edition and above)
-
-# 1. Make sure you add a valid GitHub configuration to your SonarQube (Administration > DevOps platforms > GitHub)
-
-# 2. Import your project on SonarQube
-#     * Add your repository as a new project by clicking "Create project" from your homepage.
-#
-# 3. Select GitHub Actions as your CI and follow the tutorial
-#     * a. Generate a new token and add it to your GitHub repository's secrets using the name SONAR_TOKEN
-#          (On SonarQube, click on your avatar on top-right > My account > Security or ask your administrator)
-#
-#     * b. Copy/paste your SonarQube host URL to your GitHub repository's secrets using the name SONAR_HOST_URL
-#
-#     * c. Copy/paste the project Key into the args parameter below
-#          (You'll find this information in SonarQube by following the tutorial or by clicking on Project Information at the top-right of your project's homepage)
