-## 2. Test Minio on Docker.
-Minio generates new access and secret keys each time you run this command. Container state is lost after you end this session. This mode is only intended for testing purpose.
+Minio needs a persistent volume to store configuration and application data. However, for testing purposes, you can launch Minio by simply passing a directory (`/export` 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.
 
 ```sh
 docker run -p 9000:9000 minio/minio server /export
 ```
 
-## 3. Run Minio Standalone on Docker.

-Minio container requires a persistent volume to store configuration and application data. Following command maps local persistent directories from the host OS to virtual config `~/.minio` and export `/export` directories.

-## 4. Run Minio Standalone on Docker with Custom Access and Secret Keys
+## Run Distributed Minio on Docker
+
+Distributed Minio can be deployed via [Docker Compose](https://docs.docker.com/compose/overview/) or [Swarm mode](https://docs.docker.com/engine/swarm/). The major difference between these two being, Docker Compose creates a single host, multi-container deployment, while Swarm mode creates a multi-host, multi-container deployment.
+
+This means Docker Compose lets you quickly get started with Distributed Minio on your computer - ideal for development, testing, staging environments. While deploying Distributed Minio on Swarm offers a more robust, production level deployment.
+
+* To deploy Distributed Minio on Docker Compose, refer [this guide](http://docs.minio.io/docs/deploy-minio-on-docker-compose).
+* To deploy Distributed Minio on Docker Swarm, refer [this guide](https://docs.minio.io/docs/deploy-minio-on-docker-swarm).
+
+## Minio Docker Tips
+
+### Minio Custom Access and Secret Keys
 
 To override Minio's auto-generated keys, you may pass secret and access keys explicitly as environment variables. Minio server also allows regular strings as access and secret keys.

+### Retrieving Container ID
+
+To use Docker commands on a specific container, you need to know the `Container ID` for that container. To get the `Container ID`, run
+
+```sh
+docker ps -a
+```
 
-## 5. Test Distributed Minio on Docker
+`-a` flag makes sure you get all the containers (Created, Running, Exited). Then identify the `Container ID` from the output.
 
-This example shows how to run 4 node Minio cluster inside different docker containers using [docker-compose](https://docs.docker.com/compose/). Please download [docker-compose.yml](https://raw.githubusercontent.com/minio/minio/master/docs/docker/docker-compose.yml) to your current working directory, docker-compose pulls the Minio Docker image.
+### Starting and Stopping Containers
 
+To start a stopped container, you can use the [`docker start`](https://docs.docker.com/engine/reference/commandline/start/) command.
 
-#### Run `docker-compose` on GNU/Linux and macOS
+```sh
+docker start <container_id>
+```
+
+To stop a running container, you can use the [`docker stop`](https://docs.docker.com/engine/reference/commandline/stop/) command.
 
 ```sh
-docker-compose pull
-docker-compose up
+docker stop <container_id>
 ```
 
-#### Run `docker-compose.exe` on Microsoft Windows
+### Minio container logs
+
+To access Minio logs, you can use the [`docker logs`](https://docs.docker.com/engine/reference/commandline/logs/) command.
 
 ```sh
-docker-compose.exe pull
-docker-compose.exe up
+docker logs <container_id>
 ```
 
-Each instance is accessible on the host at ports 9001 through 9004, proceed to access the Web browser at http://127.0.0.1:9001/

+To monitor the resources used by Minio container, you can use the [`docker stats`](https://docs.docker.com/engine/reference/commandline/stats/) command.

+
+Docker Compose allows defining and running single host, multi-container Docker applications.
+
+With Compose, you use a Compose file to configure Minio services. Then, using a single command, you can create and launch all the Distributed Minio instances from your configuration. Distributed Minio instances will be deployed in multiple containers on the same host. This is a great way to set up development, testing, and staging environments, based on Distributed Minio. 
+
+## 1. Prerequisites
+
+* Familiarity with [Docker Compose](https://docs.docker.com/compose/overview/).
+* Docker installed on your machine. Download the relevant installer from [here](https://www.docker.com/community-edition#/download).
+
+## 2. Run Distributed Minio on Docker Compose
+
+To deploy Distributed Minio on Docker Compose, please download [docker-compose.yaml](https://github.com/minio/minio/blob/master/docs/orchestration/docker-compose/docker-compose.yaml?raw=true) to your current working directory. Note that Docker Compose pulls the Minio Docker image, so there is no need to explicitly download Minio binary. Then run one of the below commands
+
+### GNU/Linux and macOS
+
+```sh
+docker-compose pull
+docker-compose up
+```
+
+### Windows
+
+```sh
+docker-compose.exe pull
+docker-compose.exe up
+```
+
+Each instance is now accessible on the host at ports 9001 through 9004, proceed to access the Web browser at http://127.0.0.1:9001/
+
+### Notes
+
+* By default the Docker Compose file uses the Docker image for latest Minio server release. You can change the image tag to pull a specific [Minio Docker image](https://hub.docker.com/r/minio/minio/).
+
+* There are 4 minio distributed instances created by default. You can add more Minio services (up to total 16) to your Minio Compose deployment. To add a service
+  * Replicate a service definition and change the name of the new service appropriately.
+  * Update the command section in each service.
+  * Update the port number to exposed for the new service. Also, make sure the port assigned for the new service is not already being used on the host.
+
+  Read more about distributed Minio [here](https://docs.minio.io/docs/distributed-minio-quickstart-guide).
+
+* Minio services in the Docker compose file expose ports 9001 to 9004. This allows multiple services to run on a host.
