 This article uses Azure CLI and PowerShell to deploy the templates.
 
+## Name and location for deployment
+
+When deploying to your subscription, you must provide a location for the deployment. You can also provide a name for the deployment. If you don't specify a name for the deployment, the name of the template is used as the deployment name. For example, deploying a template named **azuredeploy.json** creates a default deployment name of **azuredeploy**.
+
+The location of subscription level deployments is immutable. You can't create a deployment in one location when there's an existing deployment with the same name but different location. If you get the error code `InvalidDeploymentLocation`, either use a different name or the same location as the previous deployment for that name.
+
+## Using template functions
+
+For subscription level deployments, there are some important considerations when using template functions:
+
+* The [resourceGroup()](resource-group-template-functions-resource.md#resourcegroup) function is **not** supported.
+* The [resourceId()](resource-group-template-functions-resource.md#resourceid) function is supported. Use it to get the resource ID for resources that are used at subscription level deployments. For example, get the resource ID for a policy definition with `resourceId('Microsoft.Authorization/roleDefinitions/', parameters('roleDefinition'))`
+* The [reference()](resource-group-template-functions-resource.md#reference) and [list()](resource-group-template-functions-resource.md#list) functions are supported.
+
 ## Assign policy
 
 The following example assigns an existing policy definition to the subscription. If the policy takes parameters, provide them as an object. If the policy doesn't take parameters, use the default empty object.
