+
+## Example Usage
+
+
+```hcl
+data "google_alloydb_cluster" "qa" {
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `cluster_id` -
+  (Required)
+  The ID of the alloydb cluster that the instance belongs to.
+  'alloydb_cluster_id'
+
+* `project` - 
+  (optional) 
+  The ID of the project in which the resource belongs. If it is not provided, the provider project is used.
+
+* `location` -
+  (optional)
+  The canonical id of the location.If it is not provided, the provider project is used. For example: us-east1.
