 ## Overview
 
 You may use this chart to reach services node-wide via your Ziti network via DNS. For example, if you create a repository or container registry Ziti service, and your cluster has no internet access, you can reach those repositories or container registries via Ziti services.
+
 **NOTE:**
 For one node kubernetes approaches like k3s, this works out-of-the-box and you can extend your coredns configuration to forward to the Ziti DNS IP, as you can see [here](https://openziti.io/docs/guides/kubernetes/workload-tunneling/kubernetes-daemonset/).
 For multinode kubernetes installations, where your cluster DNS could run on a different node, you need to install the [node-local-dns](https://kubernetes.io/docs/tasks/administer-cluster/nodelocaldns/) feature, which secures that the Ziti DNS name will be resolved locally, on the very same tunneler, as Ziti Intercept IPs can change from node to node. See [this](https://github.com/lablabs/k8s-nodelocaldns-helm) helm chart for a possible implementation.

 If you want to resolve your Ziti domain inside the pods, you need to customize CoreDNS. See [Official docs](https://openziti.io/docs/guides/kubernetes/workload-tunneling/kubernetes-daemonset/).
 
+#### Multinode example
+Customise ConfigMap that you apply for node-local-dns by appending the ziti specific domain and the upstream DNS server of ziti-edge-tunnel,
