+# Simple shared VPC Project
+
+This example:
+
+* Enables shared VPC on a host project
+* Attaches a service project
+* Reserves an internal IP address in a subnet of a Shared VPC network
+* Creates a VM instance
+
+The IP address configuration object is created in the service
+project. Its value can come from the range of available addresses in
+the chosen shared subnet, or you can specify an address.
