-# More GitHub Actions for Azure: https://github.com/Azure/actions
+# This workflow will build and push a node.js application to an Azure Web App when a commit is pushed to your default branch.
+#
+# This workflow assumes you have already created the target Azure App Service web app.
+# For instructions see https://docs.microsoft.com/en-us/azure/app-service/quickstart-nodejs?tabs=linux&pivots=development-environment-cli
+#
+# To configure this workflow:
+#
+# 1. Download the Publish Profile for your Azure Web App. You can download this file from the Overview page of your Web App in the Azure Portal.
+#    For more information: https://docs.microsoft.com/en-us/azure/app-service/deploy-github-actions?tabs=applevel#generate-deployment-credentials
+#
+# 2. Create a secret in your repository named AZURE_WEBAPP_PUBLISH_PROFILE, paste the publish profile contents as the value of the secret.
+#    For instructions on obtaining the publish profile see: https://docs.microsoft.com/azure/app-service/deploy-github-actions#configure-the-github-secret
+#
+# 3. Change the value for the AZURE_WEBAPP_NAME. Optionally, change the AZURE_WEBAPP_PACKAGE_PATH and PHP_VERSION environment variables below.
