+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `region_id` - (Optional, String) Specifies the region ID.
+
+* `display_name` - (Optional, String) Specifies the region dispaly name.
+
+## Attribute Reference
+
+In addition to all arguments above, the following attributes are exported:
+
+* `id` - The data source ID.
+
+* `regions` - The region list.
