 Policy  | Description | Prerequisites
 ------- | ----------- | -------------
+[Advanced Cluster Security Secured Clusters](./acs-secure) | Applies the Advanced Cluster Security Secured Cluster operator to all managed clusters | The default placement applies the Secured Cluster resources to all OpenShift clusters except the hub cluster.
 [OpenShift Best Practices](./ocp-best-practices) | Applies the OpenShift management best practices to OpenShift clusters. | Requires placement on OpenShift 4.6 clusters or newer. The `PolicySet` uses cluster `Placement` and not the `PlacementRule` placement mechanism.
 [OpenShift Platform Plus (moved to stable)](../stable/openshift-plus) | The OpenShift Platform Plus policy set applies several policies that installs the OpenShift Platform Plus products using best practices that allow them to work well together. | The OpenShift Platform Plus policy set works with OpenShift managed clusters and installs many components to the hub cluster. See the policy set [README.md](../stable/openshift-plus/README.md) for more information on prerequisites. The `PolicySet` uses cluster `Placement` and not the `PlacementRule` placement mechanism.
 [Kyverno Policy Sets](./kyverno) | The Kyverno policy sets are provided to help you apply best practices around security, multitenancy and applications. See the details for each each of the policy sets in the `kyverno` subdirectories. | The Kyverno `PolicySets` require the Kyverno helm chart to be installed on each managed cluster where you want to install the `PolicySets`.  Use the policy [`policy-install-kyverno`](https://raw.githubusercontent.com/open-cluster-management-io/policy-collection/main/community/CM-Configuration-Management/policy-install-kyverno.yaml) to install kyverno and the policy [`policy-kyverno-config-exclude-resources`](https://raw.githubusercontent.com/open-cluster-management-io/policy-collection/main/community/CM-Configuration-Management/policy-kyverno-config-exclude-resources.yaml) to update Kyverno resource filters. The `PolicySet` uses cluster `Placement` and not the `PlacementRule` placement mechanism.  For more details on Kyverno `PolicySet` installation, see the [README.md](./kyverno/README.md).

+# Advanced Cluster Security PolicySet for Secured Clusters
+
+## Prerequisites
+
+To install Advanced Cluster Security Secured Clusters using this PolicySet, 
+you must have already installed your Advanced Cluster Security Central Server.
+The policies make the following assumptions:
+
+ - RHACS is installed on the RHACM hub and the ACS init bundle secrets are created
+   in the `stackrox` namespace.
+ - RHACS is installed on the RHACM hub and the ACS Central Server `Route` resource 
+   exists in the `stackrox` namespace.
+ - An install of Red Hat Advanced Cluster Management for Kubernetes version 2.8
+   or newer is required.
+
+
+## Installation
+
+The ACS PolicySet for Secured Clusters contains two `PolicySets` that will be deployed.
+The `PolicySets` install RHACS Secured Clusters onto all OpenShift clusters that are 
+managed by RHACM except for the RHACM hub cluster.  If you want to install the RHACS
+Secured Cluster component to the RHACM hub, that must be done separately.
+
+Prior to applying the `PolicySet`, perform these steps:
+
+1. Install the Policy generator Kustomize plugin by following the [installation instructions](https://github.com/open-cluster-management-io/policy-generator-plugin#installation). It is recommended to use Kustomize v4.5+.
+2. Policies are installed to the `policies` namespace.
+   Make sure the placement bindings match this namespace for the hub and other managed clusters.
+   Example yaml to apply a ManagedClusterSetBinding for the policies namespace.
+
+    ```yaml
+    apiVersion: cluster.open-cluster-management.io/v1beta2
+    kind: ManagedClusterSetBinding
+    metadata:
+        name: default
+        namespace: policies
+    spec:
+        clusterSet: default
+    ```
+    ```bash
+    oc apply -f managed-cluster.yaml 
+    ```
+
+Apply the policies using the kustomize command or subscribing to a fork of the repository and pointing to this directory.  See the details for using the Policy Generator for [more information](https://github.com/stolostron/policy-collection/tree/main/policygenerator).  The command to run is `kustomize build --enable-alpha-plugins  | oc apply -f -`
+
+**Note**: If the RHACS `Route` or certificate bundles are not available on the RHACM 
+hub cluster, you must edit the policy resources to make sure these resources are
+available in the `policies` namespace.
