+# flexibleengine_compute_servergroups
+
+Use this data source to get the list of the compute server groups.
+
+## Example Usage
+
+```hcl
+variable "name" {}
+
+data "flexibleengine_compute_servergroups" "test" {
+  name = var.name
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `region` - (Optional, String) Specifies the region in which to obtain the server groups.
+  If omitted, the provider-level region will be used.
+
+* `name` - (Optional, String) Specifies the server group name.
+
+## Attribute Reference
+
+In addition to all arguments above, the following attributes are exported:
+
+* `id` - The data source ID.
+
+* `servergroups` - List of ECS server groups details. The [servergroups](#ecs_servergroups) object structure is
+  documented below.
+
+<a name="ecs_servergroups"></a>
+The `servergroups` block supports:
+
+* `id` - The server group ID in UUID format.
+
+* `name` - The server group name.
+
+* `policies` - The set of policies for the server group.
+
+* `members` - An array of one or more instance ID attached to the server group.
