 ## Deploy the template
 
 For the deployment procedure, see the "Deploy the template" section of [Tutorial: Create ARM templates with dependent resources](./template-tutorial-create-templates-with-dependent-resources.md#deploy-the-template). We recommended that you use a generated password for the virtual machine administrator account. See this article's [Prerequisites](#prerequisites) section.
