 ## Upgrade Instructions
 
 ### 1.32 -> 1.33
+
 Updating the {{product}} snap to version 1.33 is straightforward in most cases. 
 If you are not using dual stack networking, you can simply run:
 
 ```bash
 sudo snap refresh k8s --channel=1.33/stable
 ```
+
 All components, including Cilium, will be updated automatically.
 
 #### Additional Steps for Dual Stack Environments
+
 If your cluster is configured with dual stack networking (IPv4 and IPv6), 
 you’ll need to make a manual adjustment before refreshing. {{product}} 1.33 
 includes Cilium v1.17, which introduces a stricter requirement for dual stack: 
 Each node must report both IPv4 and IPv6 addresses to the API server. 
 If this is not satisfied, the Cilium agent pods will fail to start. 
 For each node in the cluster, perform the following steps:
+
 - Edit the kubelet configuration:
+
 ```bash
 sudo nano /var/snap/k8s/common/args/kubelet
 ```
+
 - Locate the --node-ip flag.
-- Add both the IPv4 and IPv6 addresses (comma-separated) from the same interface:
+- Add both the IPv4 and IPv6 addresses (comma-separated) from the same 
+interface:
+
 ```bash
 --node-ip=<IPv4>,<IPv6>
 ```
+
 - Restart the `kubelet` service
+
 ```bash
 sudo systemctl restart snap.k8s.kubelet.service
 ```
+
 - Restart the Cilium DaemonSet:
+
 ```bash
 sudo k8s kubectl rollout restart daemonset cilium -n kube-system
 ```
