 It is is based on a greate article by [Olav S. Thoresen: Talos cluster on Proxmox with Terraform](https://olav.ninja/talos-cluster-on-proxmox-with-terraform).  
 In addition to the configuration provided by the article, this module enables you to provision a HA control plane and any number of worker nodes.

 Write Kubeconfig (caution, this will override you existing Kubeconfig):
-```
+```shell
 terraform output -raw kubeconfig > ~/.kube/config
 ```
 
+Verify:
+```shell
+kubectl get nodes
+```
