+# google\_compute\_region\_instance\_group\_manager
+
+Get a Compute Region Instance Group Manager within GCE.
+For more information, see [the official documentation](https://cloud.google.com/compute/docs/instance-groups/distributing-instances-with-regional-instance-groups)
+and [API](https://cloud.google.com/compute/docs/reference/rest/v1/regionInstanceGroupManagers)
+
+## Example Usage
+
+```hcl
+data "google_compute_region_instance_group_manager" "rigm" {
+  name = "my-igm"
+  region = "us-central1"
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `self_link` - (Optional) The self link of the instance group. Either `name` or `self_link` must be provided.
+
+* `name` - (Optional) The name of the instance group. Either `name` or `self_link` must be provided.
+
+* `project` - (Optional) The ID of the project in which the resource belongs. If it is not provided, the provider project is used.
+
+* `Region` - (Optional) The region where the managed instance group resides. If not provided, the provider region is used.
+
+---
+
+## Attributes Reference
