+# 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 SonarCloud analysis of your code and populates
+# GitHub Code Scanning alerts with the vulnerabilities found.
+# Free for open source project.
+
+# 1. Login to SonarCloud.io using your GitHub account
+
+# 2. Import your project on SonarCloud
+#     * Add your GitHub organization first, then add your repository as a new project.
+#     * Please note that many languages are eligible for automatic analysis,
+#       which means that the analysis will start automatically without the need to set up GitHub Actions.
+#     * This behavior can be changed in Administration > Analysis Method.
+#
+# 3. Follow the SonarCloud in-product tutorial
+#     * a. Copy/paste the Project Key and the Organization Key into the args parameter below
+#          (You'll find this information in SonarCloud. Click on "Information" at the bottom left)
+#
+#     * b. Generate a new token and add it to your Github repository's secrets using the name SONAR_TOKEN
+#          (On SonarCloud, click on your avatar on top-right > My account > Security
+#           or go directly to https://sonarcloud.io/account/security/)
