-This chapter uses a cluster with 3 master nodes and 5 worker nodes as described here: link:../cluster-install#multi-master-multi-node-multi-az-gossip-based-cluster[multi-master, multi-node gossip based cluster].
+In order to perform exercises in this chapter, you’ll need to deploy configurations to a Kubernetes cluster. To create an EKS-based Kubernetes cluster, use the link:../../01-path-basics/102-your-first-cluster#create-a-kubernetes-cluster-with-eks[AWS CLI] (recommended). If you wish to create a Kubernetes cluster without EKS, you can instead use link:../../01-path-basics/102-your-first-cluster#alternative-create-a-kubernetes-cluster-with-kops[kops].
 
 All configuration files for this chapter are in the `roles` directory.
