+See our web documentation on [Deploying MinIO in Standalone Mode](Deploy Standalone MinIO in a Container) for a more structured tutorial on deploying MinIO in a container.

 ## Prerequisites
 Docker installed on your machine. Download the relevant installer from [here](https://www.docker.com/community-edition#/download).
 
 ## Run Standalone MinIO on Docker.
-MinIO needs a persistent volume to store configuration and application data. However, for testing purposes, you can launch MinIO by simply passing a directory (`/data` in the example below). This directory gets created in the container filesystem at the time of container start. But all the data is lost after container exits.
+
+*Note*: Standalone MinIO is intended for early development and evaluation. For production clusters, deploy a [Distributed](https://docs.min.io/minio/baremetal/installation/deployment-and-management.html) MinIO deployment.

 #### GNU/Linux and macOS
 ```sh

 docker run \

   quay.io/minio/minio server /data --console-address ":9001"
 ```
 
+The command creates a new local directory `~/minio/data` in your user home directory. It then starts the MinIO container with the `-v` argument to map the local path (`~/minio/data`) to the specified virtual container directory (`/data`). When MinIO writes data to `/data`, that data is actually written to the local path `~/minio/data` where it can persist between container restarts.
