+# Simple Regional Autopilot Cluster
+
+This example illustrates how to create a simple autopilot cluster with beta features and
+not using the default service account.
+
+<!-- BEGINNING OF PRE-COMMIT-TERRAFORM DOCS HOOK -->
+## Inputs
+
+| Name | Description | Type | Default | Required |
+|------|-------------|------|---------|:--------:|
+| project\_id | The project ID to host the cluster in | `any` | n/a | yes |
+
+## Outputs
+
+| Name | Description |
+|------|-------------|
+| cluster\_name | Cluster name |
+| kubernetes\_endpoint | The cluster endpoint |
+| location | n/a |
+| master\_kubernetes\_version | Kubernetes version of the master |
+| network\_name | The name of the VPC being created |
+| region | The region in which the cluster resides |
+| service\_account | The service account to default running nodes as if not overridden in `node_pools`. |
+| subnet\_names | The names of the subnet being created |
+| zones | List of zones in which the cluster resides |
+
+<!-- END OF PRE-COMMIT-TERRAFORM DOCS HOOK -->
+
+To provision this example, run the following from within this directory:
+- `terraform init` to get the plugins
+- `terraform plan` to see the infrastructure plan
+- `terraform apply` to apply the infrastructure build
+- `terraform destroy` to destroy the built infrastructure
