+You can use the resources created in this topic with other tutorials and quickstarts in this document set. If you plan to continue on to work with other quickstarts or with the tutorials, do not clean up the resources created in this topic. If you do not plan to continue, use the following steps to delete all resources created by this topic in the Azure portal.
