+# VPC with Outpost Subnet
+
+Configuration in this directory creates a vpc with public / private / and a private outpost subnet.
+
+This configuration uses Availability Zone IDs and Availability Zone names for demonstration purposes. Normally, you need to specify only names or IDs.
+
+[Read more about AWS regions, availability zones and local zones](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-regions-availability-zones.html#concepts-regions-availability-zones).
+
+## Usage
+
+To run this example you need to execute:
+
+```bash
+$ terraform init
+$ terraform plan
+$ terraform apply
+```
+
+Note that this example may create resources which can cost money (AWS Elastic IP, for example). Run `terraform destroy` when you don't need these resources.

+## Requirements
+
+| Name | Version |
+|------|---------|
+| terraform | >= 0.13.0 |
+| aws | >= 3.0 |
+
+## Providers
+
+No provider.
+
+## Inputs
+
+| Name | Description |
+|------|-------------|
+| outpost_arn | The ARN of the outpost where you would like subnet deployed |
+| outpost_az | AZ where outpost is anchored|
+
+Note - without these input variables the subnet(s) will still create however they will be homed to the region not the outpost.
+
+## Outputs
+
+| Name | Description |
+|------|-------------|
+| azs | A list of availability zones spefified as argument to this module |
+| nat\_public\_ips | List of public Elastic IPs created for AWS NAT Gateway |
+| private\_subnets | List of IDs of private subnets |
+| public\_subnets | List of IDs of public subnets |
+| outpost\_subnets | List of IDs of the outpost subnets |
+| vpc\_cidr\_block | The CIDR block of the VPC |
+| vpc\_id | The ID of the VPC |
