+    - the minimized image (about 600M): shipped with all bootstrap files but no dependency docker images. When you start the playground, you will wait for a while to download the latest docker images, minikube framework and other packages.
     ```bash
-    wget -c http://cdn.sqlflow.tech/latest/SQLFlowPlayground.ova
+    wget -c http://cdn.sqlflow.tech/latest/SQLFlowPlaygroundBare.ova
+    ```
+    - the full installed image (about 2G): with all dependencies, no extra downloading is needed when starting. Note that in this case, the images will not be updated automatically, you will do it manually when needed.
+    ```bash
+    wget -c http://cdn.sqlflow.tech/latest/SQLFlowPlaygroundFull.ova
     ```
 1. optional, the [sqlflow](https://github.com/sql-machine-learning/sqlflow/blob/develop/doc/run/cli.md) command-line tool released by SQLFlow CI.
