 ## Prerequisites
 
-1. Provisioning of four [VLAN attachments](https://cloud.google.com/network-connectivity/docs/interconnect/concepts/partner-overview) in the Hub project in the specified environment. That would be the `prj-c-{base|restricted}-net-hub` under the folder `fldr-common` in case of Hub and Spoke architecture.

-Without Hub and Spoke enabled VLAN attachments will be created in `prj-{p|n|d}-shared-{base|restricted}` under corresponding environment's folder.
+1. Provisioning of four [VLAN attachments](https://cloud.google.com/network-connectivity/docs/interconnect/concepts/partner-overview) in the Hub project in the specified environment. That would be the `prj-c-{base|restricted}-net-hub` and  `prj-c-dns-hub` under the folder `fldr-common` in case of Hub and Spoke architecture.
 
 ## Usage
 
-1. Rename `partner_interconnect.tf.example` to `partner_interconnect.tf` in the environment folder in `3-networks-hub-and-spoke/modules/base_env` .
-1. Update the `enable_partner_interconnect` to `true` in each `main.tf` file in the environment folder in `3-networks-hub-and-spoke/envs/<environment>` .
+1. Rename `partner_interconnect.tf.example` to `partner_interconnect.tf`in the shared envs folder in `3-networks-hub-and-spoke/envs/shared`.
+1. Rename `partner_interconnect.auto.tfvars.example` to `partner_interconnect.auto.tfvars` in the shared envs folder in `3-networks-hub-and-spoke/envs/shared`.
 1. Update the file `partner_interconnect.tf` with values that are valid for your environment for the VLAN attachments, locations.
