 ## Installing the Amazon EBS CSI Driver
-    You need to install the Elastic Block Store (EBS) Container Storage Interface (CSI) Driver so the EKS cluster can manage Amazon EBS volumes.  This is necessary if you want to run any application that has a database, such as Prometheus.  
-    1. First, attach an OpenID Connect (OIDC) identity provider so that applications within the EKS cluster can access AWS resources.  Execute the command `eksctl utils associate-iam-oidc-provider --region=<cluster_region> --cluster=<cluster_name> --approve`.
-    2. Next, grant the prospective EBS CSI driver IAM permissions to call the AWS APIs with this command:

 ## Deploying the sample application
-    1. Execute the command `cd {your_path}/Chronos/examples/AWS/AWS-EKS` so you are in the AWS-EKS directory.
-    2. Execute the command `kubectl apply -f knote` to deploy the sample application. 
-    3. Run `kubectl get pods` to monitor the status of the pods.  Wait until all pods go from status 'ContainerCreating' to 'Running.'
-    4. Run `kubectl get service knote` and visit the external IP address.  Add some notes or images to your functioning application!
