+# Amazon EKS Cluster: Hello World!
+
+This example deploys an EKS Kubernetes cluster.
+
+## Prerequisites
+
+[Follow the instructions](https://www.pulumi.com/docs/clouds/aws/get-started/begin/)
+to get started with Pulumi & AWS.
+
+## Deploying
+
+1. Create a new stack, which is an isolated deployment target for this example:
+
+   ```bash
+   pulumi stack init aws-eks
+   ```
+
+2. Set the AWS region:
+
+   ```bash
+   pulumi config set aws:region us-west-2
+   ```
+
+   We recommend using `us-west-2` to host your EKS cluster as other regions (notably `us-east-1`) may have capacity issues that prevent EKS
+   clusters from creating.
+
+3. Stand up the EKS cluster:
+
+   ```bash
+   pulumi up
+   ```
+4. After 10-15 minutes, your cluster will be ready, and the `kubeconfig` JSON you'll use to connect to the cluster will
+   be available as an output. You can save this `kubeconfig` to a file like so:
+
+   ```bash
+   pulumi stack output kubeconfig > kubeconfig.json
+   ```
+
+   Once you have this file in hand, you can interact with your new cluster as usual via `kubectl`:
+
+   ```bash
+   kubectl --kubeconfig=./kubeconfig.json get all --all-namespaces
+   ```
+
+5. And finally - open the application in your browser to see the running application.
+
+   ```bash
+   curl http://$(pulumi stack output serviceHostname)
+   ```
+
+6. To clean up resources, destroy your stack and remove it:
+
+   ```bash
+   pulumi destroy
+   ```
+   ```bash
+   pulumi stack rm aws-eks
+   ```
