+## The netshoot kubectl plugin
+
+To easily troubleshoot networking issues in your k8s environment, you can leverage the [Netshoot Kubeclt Plugin](https://github.com/nilic/kubectl-netshoot) (shout out to Nebojsa Ilic for creating it!). Using this kubectl plugin, you can easily create ephemeral `netshoot` containers to troubleshoot existing pods, k8s controller or worker nodes. To install the plugin, follow [these steps](https://github.com/nilic/kubectl-netshoot#installation).
+
+Sample Usage:
+
+```
+# spin up a throwaway pod for troubleshooting
+kubectl netshoot run tmp-shell
+
+# debug using an ephemeral container in an existing pod
+kubectl netshoot debug my-existing-pod
+
+# create a debug session on a node
+kubectl netshoot debug node/my-node
+```
