+## Example - Deoloy Dualstack Cluster 
+You can deploy a dual stack cluster with this role. There are some important considerations to make: 
+- You have to define both, `cluster_cidr` and `service_cidr` with IPv4 and IPv6 address spaces. 
+- Make sure both address spaces are big enough so that each node can get a `/node_cidr_mask_ipv4` and a `/node_cidr_mask_ipv6` from the `cluster_cidr` address space. (Hence the more complex IPv6 example here)
+- A dual stack VIP is currently not supported by the role.
