+# KWOK (Kubernetes WithOut Kubelet)
+
+[KWOK](https://github.com/kubernetes-sigs/kwok/) - Simulates thousands of Nodes and Clusters.
+
+## Installing the Chart
+
+Before you can install the chart you will need to add the `kwok` repo to [Helm](https://helm.sh/).
+
+```shell
+helm repo add kwok https://kwok.sigs.k8s.io/charts/
+```
+
+After you've installed the repo you can install the chart.
+
+```shell
+helm upgrade --namespace kube-system --install kwok kwok/kwok
+```
+
+Set up default stage policy (required)
+> NOTE: This configures the pod/node emulation behavior, if not it will do nothing.
+
+```shell
+helm upgrade --install kwok kwok/stage-fast
+```
+
+## Configuration
+
+The following table lists the configurable parameters of the kwok chart and their default values.
