 ## Playground usage
 
-### Launch playground
+### One curl command launch playground
+
+```shell
+/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/apache/gravitino-playground/HEAD/install.sh)"
+```
+
+### Use git to download and launch playground
 
 ```shell
 git clone [email protected]:apache/gravitino-playground.git
 cd gravitino-playground
-./playground.sh start
 ```
 
-### Check status
+#### Docker
+
+##### Start
+
+```
+./playground.sh docker start
+```
+
+##### Check status
+
+```shell 
+./playground.sh docker status
+```
+
+##### Stop playground
+
+```shell
+./playground.sh docker stop
+```
+
+#### Kubernetes
+
+Enable Kubernetes in Docker Desktop or Orbstack.
+
+In Project root directory, execute this command:
+
+```
+helm upgrade --install gravitino-playground ./helm-chart/ --create-namespace --namespace gravitino-playground --set projectRoot=$(pwd)
+```
+
+##### Start
+
+```
+./playground.sh k8s start
+```
+
+##### Check status
+
 ```shell 
-./playground.sh status
+./playground.sh k8s status
 ```
-### Stop playground
+
+##### Port Forwarding
+
+To access pods or services at `localhost`, you needs to do these steps:
+
+1. Log in to the Gravitino playground Trino pod using the following command:
+
+```
+TRINO_POD=$(kubectl get pods --namespace gravitino-playground -l app=trino -o jsonpath="{.items[0].metadata.name}")
+kubectl exec $TRINO_POD -n gravitino-playground -it -- /bin/bash
+```
+
+2. Log in to the Gravitino playground Spark pod using the following command:
+
+```
+SPARK_POD=$(kubectl get pods --namespace gravitino-playground -l app=spark -o jsonpath="{.items[0].metadata.name}")
+kubectl exec $SPARK_POD -n gravitino-playground -it -- /bin/bash
+```
+
+3. Port-forwarding Gravitino Service, so that you can access it at `localhost:8090`.
+
+```
+kubectl port-forward svc/gravitino -n gravitino-playground 8090:8090      
+```
+
+4. Port-forwarding Jupyter Notebook Service, so that you can access it at `localhost:8888`.
+
+```
+kubectl port-forward svc/jupyternotebook -n gravitino-playground 8888:8888
+```
+
+##### Stop playground
+
 ```shell
-./playground.sh stop
+./playground.sh k8s stop
 ```
