-## Prepare Environment
+### Prepare Environment (Optional)
 **To run this example, you need to have a kubernetes cluster with istio installed.**
 * If you don't have a k8s cluster, we recommend using docker desktop to get started. It has an embedded k8s cluster.
   * [install docker desktop](https://www.docker.com/products/docker-desktop/)

 * If you are not using docker desktop, you need to install docker to build and manage image.
 
-* Use `docker run -d -p 5000:5000 --name local-registry registry:2` to enable local image repository.
----
-## Deploy Example
+## Remote Deployment
+Run the following command to deploy pre-prepared images:
+
+```shell
+kubectl apply -f
+```
+
+## Local Development
+If you have code changed locally and want to deploy it to remote cluster, follow the instructions below to learn how to build and deploy from source code.
+
+### Deploy Example
+> Use `docker run -d -p 5000:5000 --name local-registry registry:2` to enable local image repository.
+
 **When you have completed the above steps:**
 * Run `chmod 777 ./start.sh ./update.sh`
 * Then, use `./update.sh` to deploy example to Kubernetes.
   * Every time you change the code, you need to run `./update.sh` again to synchronize the changes to Kubernetes.
----
-## Start debugging
+
+### Start debugging
 * Every time you run ./update.sh, it will start port forward to demo containers. So you can use `Remote Debug` in your IDE to start debugging directly.
 
 * You can also simply use ./port_forward.sh to start port forward.
