 ## Setup
 
-Although it is not necessary to use Amazon Elastic Kubernetes Service (Amazon EKS) with ACK, this guide assumes that you have access to an Amazon EKS cluster. If this is your first time creating an Amazon EKS cluster, see [Amazon EKS Setup](https://docs.aws.amazon.com/deep-learning-containers/latest/devguide/deep-learning-containers-eks-setup.html). For automated cluster creation using `eksctl`, see [Getting started with Amazon EKS - `eksctl`](https://docs.aws.amazon.com/eks/latest/userguide/getting-started-eksctl.html) and create your cluster with Amazon EC2 Linux managed nodes.

 For example, to specify that the Amazon MemoryDB API calls go to the `us-east-1` region, you can deploy the service controller with the following command:
 
 ```bash
-helm install --create-namespace -n ack-system oci://public.ecr.aws/aws-controllers-k8s/memorydb-chart --version=v0.0.1 --generate-name --set=aws.region=us-east-1

 ```
+You can find the latest version of ACK MemoryDB controller on GitHub [release page](https://github.com/aws-controllers-k8s/memorydb-controller/releases).
+Replace value for `--version` to the desired version.
 
 For a full list of available values to the Helm chart, please [review the values.yaml file](https://github.com/aws-controllers-k8s/memorydb-controller/blob/main/helm/values.yaml).
 
 ### Configure IAM permissions
 
-Once the service controller is deployed, you will need to [configure the IAM permissions][irsa-permissions] for the controller to query the Amazon MemoryDB API. For full details, please review the AWS Controllers for Kubernetes documentation for [how to configure the IAM permissions][irsa-permissions]. If you follow the examples in the documentation, use the value of `memorydb` for `SERVICE`.
