+This platform offers APIs for setting up fully configured AKS clusters
+with secure networking, stateful cloud services (Database) that can securely
+connect to the AKS clusters, an Observability Stack, and a GitOps
+System. All these components are built using cloud service tools from
+the [Official Upbound Family Azure Provider](https://marketplace.upbound.io/providers/upbound/provider-family-azure).
+App deployments can securely connect to the infrastructure they need using secrets
 distributed directly to the app namespace.
 
 ## Overview
 
-This reference platform defines a custom API for creating an AKS cluster
-([XCluster](package/cluster/definition.yaml)) which includes the actual AKS
-cluster, a network fabric and Prometheus and other cluster services
-([XServices](package/cluster/composition.yaml)). Additionally it defines a
-custom API for provisioning Postgres Databases
-([XPostgreSQLInstance](package/database/postgres/definition.yaml)).
+This reference platform outlines a specialized API for generating an AKS cluster
+([XCluster](apis/cluster/definition.yaml)) that incorporates XRs from the specified configurations:
