+    The Bicep file requires an existing virtual machine. Before deploying the Bicep file, the script deploys an ARM template located at *https://raw.githubusercontent.com/Azure/azure-quickstart-templates/master/quickstarts/microsoft.portal/azure-portal-dashboard/prereqs/prereq.azuredeploy.json* for creating a virtual machine. The virtual machine name is hard-coded as **SimpleWinVM** in the ARM template.
