+With our Red Hat Advanced Cluster Security Operator installed and standing by to do some work for us, let's give it some work to do by telling it to deploy Red Hat Advanced Cluster Security for us.
+
+## 4.1 - Getting familiar with rhacs

+Fundamentally you install RHACS as a set of containers in your OpenShift Container Platform or Kubernetes cluster. RHACS includes the following services:
+
+1. **Central** services you install on a designated "hub" cluster.
+2. **Secured cluster** services you install on each cluster you want to secure by RHACS.
