 ## Remarks
 
-- If specified, `defaultValue.name` is automatically validated for uniqueness. If the storage account name isn't unique, the user must specify a different name or choose an existing storage account.
-- The default value for `defaultValue.type` is **Premium_LRS**.
+- The `defaultValue.name` is required and the value is automatically validated for uniqueness. If the storage account name isn't unique, the user must specify a different name or choose an existing storage account.
+- The default value for `defaultValue.type` is **Premium_LRS**. You can set any storage account type as the default value. For example, _Standard_LRS_ or _Standard_GRS_.
 - Any type not specified in `constraints.allowedTypes` is hidden, and any type not specified in `constraints.excludedTypes` is shown. `constraints.allowedTypes` and `constraints.excludedTypes` are both optional, but can't be used simultaneously.
-- If `options.hideExisting` is **true**, the user can't choose an existing storage account. The default value is **false**.
+- If `options.hideExisting` is **true**, the user can't choose an existing storage account. The default value is **false**. The control only shows storage accounts as _existing_ if they are in same resource group and region as the selections made on the **Basics** tab.
+- The `kind` property displays the value if a new storage account was created, or an existing storage account's value.
+
+## Example
+
+The default values for the storage account name and type are examples. You can set your own default values for your environment.
+
+In the `outputs` section, the `storageSelector` output includes all the values for a storage account. The `storageKind` and `storageName` are examples of how to output specific values.
