+### Deploy helm chart on the Kubernetes cluster
+
+1. Create namespace managed by Helm:
+    ```bash
+   kubectl apply -f - << EOF
+   apiVersion: v1
+   kind: Namespace
+   metadata:
+     name: confidential-containers-system
+     labels:
+       app.kubernetes.io/managed-by: Helm
+     annotations:
+       meta.helm.sh/release-name: peerpods
+       meta.helm.sh/release-namespace: confidential-containers-system
+   EOF
+    ```
+
+2. Create the secret using `kubectl`:
+
+   See [providers/aws-secrets.yaml.template](https://github.com/confidential-containers/cloud-api-adaptor/blob/main/src/cloud-api-adaptor/install/charts/peerpods/providers/aws-secrets.yaml.template) for required keys.
+
+    ```bash
+    kubectl create secret generic my-provider-creds \
+    -n confidential-containers-system \
+    --from-literal=AWS_ACCESS_KEY_ID=$AWS_ACCESS_KEY_ID \
+    --from-literal=AWS_SECRET_ACCESS_KEY=${AWS_SECRET_ACCESS_KEY} \
+    --from-file=id_rsa.pub="$SSH_KEY"
+    ```
+
+   > **Note**: The values should be without quotes
+
+   > **Note**: `--from-file=id_rsa.pub="$SSH_KEY"` is optional. It allows user to SSH into the pod VMs for troubleshooting purposes.
+   > This option works only for custom debug enabled pod VM images. The prebuilt pod VM images do not have SSH connection enabled.
+
+3. Install helm chart:
+
+   Below command uses customization options `-f` and `--set` which are described [here](../../getting-started/installation/advanced_configuration).
+
+    ```bash
+    helm install peerpods . \
+      -f providers/aws.yaml \
+      --set secrets.mode=reference \
+      --set secrets.existingSecretName=my-provider-creds \
+      --dependency-update \
+      -n confidential-containers-system
+    ```
+
+Generic Peer pods Helm charts deployment instructions are also described
+[here](https://github.com/confidential-containers/cloud-api-adaptor/tree/main/src/cloud-api-adaptor/install/charts/peerpods/README.md).
