 This is a validated pattern for deploying confidential containers on OpenShift.
 
-The target operating model has two clusters:
+There are two topologies for deploying this pattern:
 
-- One in a "trusted" zone where the remote attestation, KMS and Key Broker infrastructure are deployed.
-- A second where a subset of workloads are deployed in confidential containers.
+1. *Default* using a single cluster. This breaks the RACI expected in a remote attestation architecture, however, makes it easier to test. This uses the `simple` `clusterGroup`.
+2. A more secure operating model that has two clusters:
+   - One in a "trusted" zone where the remote attestation, KMS and Key Broker infrastructure are deployed. This is also the Advanced Cluster Manager Hub cluster. It uses the `trusted-hub` `clusterGroup`.
+   - A second where a subset of workloads are deployed in confidential containers. It uses the `spoke` `clusterGroup`

+On the cluster where confidential workloads are deployed two sample applications are deployed:
 
 1. Sample hello world applications to allow users to experiment with the policies for CoCo and the KBS (trustee).
 2. A sample application `kbs-access` which presents secrets obtained from trustee to a web service. This is designed to allow users to test locked down environments.
 
 Future work includes:
 
-1. Supporting a multiple cluster deployment
-2. Supporting multiple infrastructure providers
-3. Supporting a more sophisticated workload such as confidential AI inference with protected GPUs.
+1. ~~Supporting a multiple cluster deployment~~ Done
+2. Supporting multiple infrastructure providers - Work in Progress.

-- Only known to work today with everything on one cluster. The work to expand this is in flight.
 - Below version 3.1, if not using ARO you must either provide your own CA signed certs, or use let's encrypt.
 - Must be on 4.16.14 or later.

-Trustee requires a trusted CA issued certificate. Let's Encrypt is included for environments without a trusted cert on OpenShift's routes.
+Trustee (guest agents) requires that Trustee uses a Mozilla trusted CA issued certificate, or a specific certificate which is known in advance. Today the pattern uses specific self signed certs. Let's encrypt was an option for getting a trusted certificate onto OpenShift's routes, and therefore Trustee. Ths functionality will be removed at a later date.
 
 If you need a Let's Encrypt certificate to be issued the `letsencrypt` application configuration needs to be changed as below.
