+# Example setup
+
+This example shows the bare minimum requirements to deploy applications on wasmCloud.
+
+It relies on the Kubernetes `default` namespace for simplicity.
+
+## Install [NATS](https://github.com/nats-io/nats-server)
+
+```bash
+helm repo add nats https://nats-io.github.io/k8s/helm/charts/
+helm upgrade --install -f nats-values.yaml nats nats/nats
+```
+
+Validate installation with:
+
+```bash
+# make sure pods are ready
+kubectl rollout status deploy,sts -l app.kubernetes.io/instance=nats
+```
+
+## Install wasmCloud Application Deployment Manager - [wadm](https://github.com/wasmCloud/wadm)
+
+```sh
+helm install wadm -f wadm-values.yaml oci://ghcr.io/wasmcloud/charts/wadm
+```
+
+Validate installation with:
+
+```bash
+# make sure pods are ready
+kubectl rollout status deploy -l app.kubernetes.io/instance=wadm
+```
+
+## Install the operator
+
+```sh
+kubectl apply -k ../../deploy/base
+```
+
+Validate installation with:
+
+```bash
+# make sure pods are ready
+kubectl rollout status deploy -l app=wasmcloud-operator -n wasmcloud-operator
+# apiservice should be available
+kubectl get apiservices.apiregistration.k8s.io v1beta1.core.oam.dev
+```
+
+## Create wasmcloud cluster
+
+```bash
+kubectl apply -f wasmcloud-host.yaml
+```
+
+Check wasmCloud host status with:
+
+```bash
+kubectl describe wasmcloudhostconfig wasmcloud-host
+```
+
+## Managing applications using kubectl
+
+Install the rust hello world application:
+
+```bash
+kubectl apply -f hello-world-application.yaml
+```
+
+Check application status with:
+
+```bash
+kubectl get applications
+```
+
+## Managing applications with wash
+
+Port forward into the NATS cluster. 4222 = NATS Service, 4223 = NATS Websockets
+
+```bash
+kubectl port-forward svc/nats 4222:4222 4223:4223
+```
+
+In another shell:
+
+```bash
+wash app list
+```
