+  Manages an Regional Instance Group within GCE.
+---
+
+# google\_compute\_region\_instance\_group\_manager
+
+The Google Compute Engine Regional Instance Group Manager API creates and manages pools
+of homogeneous Compute Engine virtual machine instances from a common instance
+template. 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/latest/regionInstanceGroupManagers)
+
+## Example Usage
+
+```hcl
+resource "google_compute_region_instance_group_manager" "appserver" {
+  name        = "appserver-igm"
+
+  base_instance_name = "app"
+  instance_template  = "${google_compute_instance_template.appserver.self_link}"
+  region             = "us-central1"
+
+  target_pools = ["${google_compute_target_pool.appserver.self_link}"]
+  target_size  = 2
+
+  named_port {
+    name = "custom"
+    port = 8888
+  }
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `base_instance_name` - (Required) The base instance name to use for
+    instances in this group. The value must be a valid
+    [RFC1035](https://www.ietf.org/rfc/rfc1035.txt) name. Supported characters
+    are lowercase letters, numbers, and hyphens (-). Instances are named by
+    appending a hyphen and a random four-character string to the base instance
+    name.
+
+* `instance_template` - (Required) The full URL to an instance template from
+    which all new instances will be created.
+
+* `name` - (Required) The name of the instance group manager. Must be 1-63
+    characters long and comply with
+    [RFC1035](https://www.ietf.org/rfc/rfc1035.txt). Supported characters
+    include lowercase letters, numbers, and hyphens.
+
+* `region` - (Required) The region where the managed instance group resides.
+
+- - -
+
+* `description` - (Optional) An optional textual description of the instance
+    group manager.
+
+* `named_port` - (Optional) The named port configuration. See the section below
+    for details on configuration.
+
+* `project` - (Optional) The project in which the resource belongs. If it
+    is not provided, the provider project is used.
+
+* `target_size` - (Optional) The target number of running instances for this managed
+    instance group. This value should always be explicitly set unless this resource is attached to
+     an autoscaler, in which case it should never be set. Defaults to `0`.
+
+* `target_pools` - (Optional) The full URL of all target pools to which new
+    instances in the group are added. Updating the target pools attribute does
+    not affect existing instances.
+
+---
+
+* `auto_healing_policies` - (Optional, [Beta](/docs/providers/google/index.html#beta-features)) The autohealing policies for this managed instance
+group. You can specify only one value. Structure is documented below.
+
+The `named_port` block supports: (Include a `named_port` block for each named-port required).
+
+* `name` - (Required) The name of the port.
+
+* `port` - (Required) The port number.
+
+The `auto_healing_policies` block supports:
+
+* `health_check` - (Required) The health check that signals autohealing.
+
+* `initial_delay_sec` - (Required) The number of seconds that the managed instance group waits before
+ it applies autohealing policies to new instances or recently recreated instances. Between 0 and 3600.
+
+## Attributes Reference
+
+In addition to the arguments listed above, the following computed attributes are
+exported:
+
+* `fingerprint` - The fingerprint of the instance group manager.
+
+* `instance_group` - The full URL of the instance group created by the manager.
+
+* `self_link` - The URL of the created resource.
+
+
+## Import
+
+Instance group managers can be imported using the `name`, e.g.
+
+```
+$ terraform import google_compute_region_instance_group_manager.appserver appserver-igm
+```
