 If you're not running on managed K8s platform such as GKE, AKS, or EKS, you can use Helm to install the Fusion chart to an existing Kubernetes cluster.
 
+For eample, you can run local https://kind.sigs.k8s.io/docs/user/quick-start/[`kind`^] k8s cluster on mac with the following commands.
+
+To install Fusion locally, you should have a node with at least 12GB of memory, 100GB of disk and 4 CPU cores. The recommended setup is 16GB (or more) of memory and 8+ CPU cores.
+```
+# assume you have https://brew.sh/[`brew`^] installed
+brew install kind
+kind create cluster
+```
+
+Then run the https://github.com/lucidworks/fusion-cloud-native/blob/master/setup_f5_k8s.sh.sh[`setup_f5_k8s.sh`^] script to install Fusion 5.x into local k8s cluster.
+```
+./setup_f5_gke.sh -c <cluster_name> -r <release> -n <namespace> --helm-chart fusion-5.0.3-2.tgz
+```
+
+Make sure all the pods are healthy and running by watching the cluster rollout using: `kubectl get pods --watch`
+
+Hit ctrl-c once all the pods are running.
+
+Run the following commands to access Fusion locally on http://localhost:6764
+```
+kubectl port-forward svc/proxy 6764:6764
+```
