+  Manage the default VPC resource.
+---
+
+# aws\_default\_vpc
+
+Provides a resource to manage the [default AWS VPC](http://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/default-vpc.html)
+in the current region.
+
+For AWS accounts created after 2013-12-04, each region comes with a Default VPC.
+**This is an advanced resource**, and has special caveats to be aware of when
+using it. Please read this document in its entirety before using this resource.
+
+The `aws_default_vpc` behaves differently from normal resources, in that
+Terraform does not _create_ this resource, but instead "adopts" it
+into management. 
+
+## Example Usage
+
+Basic usage with tags:
+
+```
+resource "aws_default_vpc" "default" {
+	tags {
+		Name = "Default VPC"
+	}
+}
+```
+
+## Argument Reference
+
+The arguments of an `aws_default_vpc` differ slightly from `aws_vpc` 
+resources. Namely, the `cidr_block`, `instance_tenancy` and `assign_generated_ipv6_cidr_block`
+arguments are computed. The following arguments are still supported: 
+
+* `enable_dns_support` - (Optional) A boolean flag to enable/disable DNS support in the VPC. Defaults true.
+* `enable_dns_hostnames` - (Optional) A boolean flag to enable/disable DNS hostnames in the VPC. Defaults false.
+* `enable_classiclink` - (Optional) A boolean flag to enable/disable ClassicLink 
+  for the VPC. Only valid in regions and accounts that support EC2 Classic.
+  See the [ClassicLink documentation][1] for more information. Defaults false.
+* `tags` - (Optional) A mapping of tags to assign to the resource.
+
+### Removing `aws_default_vpc` from your configuration
+
+The `aws_default_vpc` resource allows you to manage a region's default VPC,
+but Terraform cannot destroy it. Removing this resource from your configuration
+will remove it from your statefile and management, but will not destroy the VPC.
+You can resume managing the VPC via the AWS Console.
+
+## Attributes Reference
+
+The following attributes are exported:
+
+* `id` - The ID of the VPC
+* `cidr_block` - The CIDR block of the VPC
+* `instance_tenancy` - Tenancy of instances spin up within VPC.
+* `enable_dns_support` - Whether or not the VPC has DNS support
+* `enable_dns_hostnames` - Whether or not the VPC has DNS hostname support
+* `enable_classiclink` - Whether or not the VPC has Classiclink enabled
+* `assign_generated_ipv6_cidr_block` - Whether or not an Amazon-provided IPv6 CIDR 
+block with a /56 prefix length for the VPC was assigned
+* `main_route_table_id` - The ID of the main route table associated with
+     this VPC. Note that you can change a VPC's main route table by using an
+     [`aws_main_route_table_association`](/docs/providers/aws/r/main_route_table_assoc.html)
+* `default_network_acl_id` - The ID of the network ACL created by default on VPC creation
+* `default_security_group_id` - The ID of the security group created by default on VPC creation
+* `default_route_table_id` - The ID of the route table created by default on VPC creation
+* `ipv6_association_id` - The association ID for the IPv6 CIDR block of the VPC
+* `ipv6_cidr_block` - The IPv6 CIDR block of the VPC
+
