+
+# aws\_vpn\_gateway\_attachment
+
+Provides a Virtual Private Gateway attachment resource, allowing for an existing
+hardware VPN gateway to be attached and/or detached from a VPC.
+
+-> **Note:** The [`aws_vpn_gateway`](vpn_gateway.html)
+resource can also automatically attach the Virtual Private Gateway it creates
+to an existing VPC by setting the [`vpc_id`](vpn_gateway.html#vpc_id) attribute accordingly.
+
+## Example Usage
+
+```
+resource "aws_vpc" "network" {
+  cidr_block = "10.0.0.0/16"

+  tags {
+    Name = "example-vpn-gateway"
+  }
+}
+
+resource "aws_vpn_gateway_attachment" "vpn_attachment" {
+  vpc_id = "${aws_vpc.network.id}"
+  vpn_gateway_id = "${aws_vpn_gateway.vpn.id}"
+}
+```
