-The `cluster_version` is the required variable. Kubernetes is evolving a lot, and each major version includes new features, fixes, or changes.

 You also need to ensure your applications and add ons are updated, or workloads could fail after the upgrade is complete. For action, you may need to take before upgrading, see the steps in the [EKS documentation](https://docs.aws.amazon.com/eks/latest/userguide/update-cluster.html).
 
-An example of harming update was the removal of several commonly used, but deprecated  APIs, in Kubernetes 1.16. More information on the API removals, see the [Kubernetes blog post](https://kubernetes.io/blog/2019/07/18/api-deprecations-in-1-16/).

+By default, this module manage the `aws-auth` configmap for you (`manage_aws_auth=true`). To avoid the following [issue](https://github.com/aws/containers-roadmap/issues/654) where the EKS creation is `ACTIVE` but not ready, we implemented a retry logic with an `local-exec` provisioner and `wget` (by default).
+
+**If you want to manage your `aws-auth` configmap, ensure you have `wget` and `/bin/sh` installed where you're running Terraform or set `wait_for_cluster_cmd` and `wait_for_cluster_interpreter` to match your needs.**
