 ## Prerequisites
 
 - An Azure account with an active subscription.
   - If you don't have one, you [can create one for free](https://azure.microsoft.com/free/).
 - Install the [Azure CLI](/cli/azure/install-azure-cli).
 - Access to a public or private container registry, such as the [Azure Container Registry](/azure/container-registry/).
+- Review the [requirements and limitations](azure-arc-overview.md) of the public preview. Of particular importance are the cluster requirements.

You could also use `az containerapp arc setup-core-dns --distro AksAzureLocal` to setup coredns for local contexts.
 
 1. Set the following environment variables to the desired name of the [Container Apps extension](azure-arc-create-container-app.md), the cluster namespace in which resources should be provisioned, and the name for the Azure Container Apps connected environment. Choose a unique name for `<connected-environment-name>`.  The connected environment name will be part of the domain name for app you'll create in the Azure Container Apps connected environment.
