• search the role requirement from azure doc for users to create resource group, then add those prereq in the content

• It is better to simplify the content of the Provision deployment foundation with Liberty on AKS section. The guide has no need to describe in detail like as a doc. Users only need to provide info in the Basics pane and leave other panes as default. After filling up the Basics pane, they can click the Review+Create button to create the resources group and cluster. Let the guide to demonstrate how simple to create them. Just mention that if interest to know more configuration, they can visit the other panes.
• in the Access the created cluster section, is there a command, e.g. az aks show, to get the [cluster-name] instead of from the GUI?
• clusterXXXXXX in the output can be replaced by a makeup string, e.g. cluster1234d5
• in the Logging into the container registry subsection, can add a command to get the [registry-name]? In this case, screenshot can be kept.

• remove

  • Please note, the plan also supports to use an existing resource group while the group is required to be empty.

• Before this statement "To push Docker images to your registry, you must log in to your Azure Container Registry by using the Azure CLI.", need to tell users which value is the [registry-name], e.g. acr1234d5 under the NAME column from the output
