 You should see the output of the Terraform script with resources created and some command pre-created for you to run the example following steps below.
 
+### Virtual Private Cloud (VPC) design
+
+As is often the case in real-world configurations, this example accepts as input an existing [Shared-VPC](https://cloud.google.com/vpc/docs/shared-vpc) via the `network_config` variable.
+
+If the `network_config` variable is not provided, one VPC will be created in each project that supports network resources (load, transformation and orchestration).
+
+When `network_config` variable is configured, the identity running the Terraform script need to have the following roles:
+  - `roles/compute.xpnAdmin` on the host project folder or org
+  - `roles/resourcemanager.projectIamAdmin` on the host project, either with no conditions or with a condition allowing [delegated role grants](https://medium.com/google-cloud/managing-gcp-service-usage-through-delegated-role-grants-a843610f2226#:~:text=Delegated%20role%20grants%20is%20a,setIamPolicy%20permission%20on%20a%20resource.) for `roles/compute.networkUser`, `roles/composer.sharedVpcAgent`, `roles/container.hostServiceAgentUser`

 ## Test your environment with Cloud Dataflow
 
 We assume all those steps are run using a user listed on `data_eng_principals`. You can authenticate as the user using the following command:
