+#### API Server VIP Management Choice
+As of v0.6.0 you can choose to use kube-vip to manage the api-server VIP instead of CPEM. By default CPEM will be used to manage the EIP that serves as the VIP for the api-server. To use kube-vip, when generating the template with `clusterctl`, pass in the `--flavor kube-vip` flag. For example, your `clusterctl generate` command might look like the following:
+
+```sh
+clusterctl generate cluster capi-quickstart \
+  --kubernetes-version v1.24.0 \
+  --control-plane-machine-count=3 \
+  --worker-machine-count=3 \
+  --infrastructure packet \
+  --flavor kube-vip
+  > capi-quickstart.yaml
+```
