+You need to have a Kubernetes cluster. Follow the [kubeadm getting started guide](/docs/getting-started-guides/kubeadm/) to bootstrap one.

+
+## Install the Weave Net addon
+
+Follow the [Integrating Kubernetes via the Addon](https://www.weave.works/docs/net/latest/kube-addon/) guide.
+
+The Weave Net addon for Kubernetes comes with a [Network Policy Controller](https://www.weave.works/docs/net/latest/kube-addon/#npc) that automatically monitors Kubernetes for any NetworkPolicy annotations on all namespaces and configures `iptables` rules to allow or block traffic as directed by the policies.
+
+## Test the installation
+
+Verify that the weave works.
+
+Enter the following command:
+
+```shell
+kubectl get po -n kube-system -o wide
+```
+
+The output is similar to this:
+
+```
+NAME                                    READY     STATUS    RESTARTS   AGE       IP              NODE
+weave-net-1t1qg                         2/2       Running   0          9d        192.168.2.10    worknode3
+weave-net-231d7                         2/2       Running   1          7d        10.2.0.17       worknodegpu
+weave-net-7nmwt                         2/2       Running   3          9d        192.168.2.131   masternode
+weave-net-pmw8w                         2/2       Running   0          9d        192.168.2.216   worknode2
+```
+
+Each Node has a weave Pod, and all Pods are `Running` and `2/2 READY`. (`2/2` means that each Pod has `weave` and `weave-npc`.)

+
+Once you have installed the Weave Net addon, you can follow the [Declare Network Policy](/docs/tasks/administer-cluster/declare-network-policy/) to try out Kubernetes NetworkPolicy. If you have any question, contact us at [#weave-community on Slack or Weave User Group](https://github.com/weaveworks/weave#getting-help).
