 The Azure Linux Container Host ships updates through two mechanisms: updated Azure Linux node images and automatic package updates.
 
-As part of the application and cluster lifecycle, we recommend keeping your clusters up to date and secured by enabling upgrades for your cluster. To automatically keep your clusters up to date and secured, you can enable automatic node-image upgrades so your cluster will use the latest Azure Linux Container Host image when it scales up. Upgrading clusters can also be done manually.

-> Any upgrade operation, whether performed manually or automatically, will upgrade the node image version if not already on the latest. The latest version is contingent on a full AKS release, and can be determined by visiting the [AKS release tracker](../../articles/aks/release-tracker.md).

 ## Prerequisites
 
-- In previous tutorials, you created and deployed an Azure Linux Container Host cluster. To complete this tutorial, you need an existing cluster. If you haven't done this step and would like to follow along, start with [Tutorial 1: Create a cluster with the Azure Linux Container Host for AKS](./tutorial-azure-linux-create-cluster.md).
-- You need the latest version of Azure CLI. Run `az --version` to find the version. If you need to install or upgrade, see [Install Azure CLI](/cli/azure/install-azure-cli).

 Auto-upgrade provides a set once and forget mechanism that yields tangible time and operational cost benefits. By enabling auto-upgrade, you can ensure your clusters are up to date and don't miss the latest Azure Linux Container Host features or patches from AKS and upstream Kubernetes.
 
-Automatically completed upgrades are functionally the same as manual upgrades. The timing of upgrades is determined by the selected channel. When making changes to auto-upgrade, allow 24 hours for the changes to take effect.

 Similar to setting your clusters to auto-upgrade, you can use the same set once and forget mechanism for package upgrades by enabling the node-os upgrade channel. If automatic package upgrades are enabled, the dnf-automatic systemd service runs daily and installs any updated packages that have been published.

 To protect your clusters, security updates are automatically applied to Azure Linux nodes. These updates include OS security fixes, kernel updates, and package upgrades. Some of these updates require a node reboot to complete the process. AKS doesn't automatically reboot these nodes to complete the update process.
 
-We recommend enabling an automatic reboot daemon such as [Kured](https://kured.dev/docs/) so that your cluster can reboot nodes that have taken kernel updates. To deploy the Kured DaemonSet in an Azure Linux Container Host cluster, see [Deploy kured in an AKS cluster](../../articles/aks/node-updates-kured.md#deploy-kured-in-an-aks-cluster)
