+A `cloudstack_domain` data source retrieves information about a domain within CloudStack.
+
+## Example Usage
+
+```hcl
+data "cloudstack_domain" "my_domain" {
+  filter {
+    name = "name"
+    value = "ROOT"
+  }
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `filter` - (Required) A block to filter the domains. The filter block supports the following:
+  * `name` - (Required) The name of the filter.

+
+## Attributes Reference
+
+The following attributes are exported:
+
