+# Compute Instance
+
+This module is used to create compute instances (and only compute instances) using
+[google_compute_instance_from_template](https://www.terraform.io/docs/providers/google/r/compute_instance_from_template.html), with no instance groups.
+
+## Usage
+
+See the [simple](https://github.com/terraform-google-modules/terraform-google-vm/tree/master/examples/compute_instance/simple) for a usage example.
+
+## Testing
+
+
+<!-- BEGINNING OF PRE-COMMIT-TERRAFORM DOCS HOOK -->
+## Inputs
+
+| Name | Description | Type | Default | Required |
+|------|-------------|------|---------|:--------:|
+| access\_config | Access configurations, i.e. IPs via which the VM instance can be accessed via the Internet. | <pre>list(object({<br>    nat_ip       = string<br>    network_tier = string<br>  }))</pre> | `[]` | no |
+| add\_hostname\_suffix | Adds a suffix to the hostname | `bool` | `true` | no |
+| hostname | Hostname of instances | `string` | `""` | no |
+| instance\_template | Instance template self\_link used to create compute instances | `any` | n/a | yes |
+| network | Network to deploy to. Only one of network or subnetwork should be specified. | `string` | `""` | no |
+| num\_instances | Number of instances to create. This value is ignored if static\_ips is provided. | `string` | `"1"` | no |
+| region | Region where the instances should be created. | `string` | `null` | no |
+| static\_ips | List of static IPs for VM instances | `list(string)` | `[]` | no |
+| subnetwork | Subnet to deploy to. Only one of network or subnetwork should be specified. | `string` | `""` | no |
+| subnetwork\_project | The project that subnetwork belongs to | `string` | `""` | no |
+| zone | Zone where the instances should be created. If not specified, instances will be spread across available zones in the region. | `string` | `null` | no |
+
+## Outputs
+
+| Name | Description |
+|------|-------------|
+| available\_zones | List of available zones in region |
+| instances\_details | List of all details for compute instances |
+| instances\_self\_links | List of self-links for compute instances |
