 New releases will include new pre-built Docker images.
 When we release a new version and include a new pre-built Docker image for it, upgrade as follows:

-
 * Shut down the docker containers
 ```bash
 $ docker-compose down
 ```

-* Manual Docker upgrade
-    1. Shut down and remove each of your Docker instances using the following commands:
-    
-        ```bash
-        $ sudo docker stop <docker-name>
-        $ sudo docker rm -v <docker-name>
-        ```

-        The Docker names are (see [Launching Docker Containers](#launch-docker)):

-        * `trains-mongo`
-        * `trains-redis`
-        * `trains-fileserver`
-        * `trains-apiserver`
-        * `trains-webserver`
-    
-    2. We highly recommend backing up your data directory!. A simple way to do that is using `tar`:
-    
-        For example, if your data directory is `/opt/trains`, use the following command:
     
     ```bash
     $ sudo tar czvf ~/trains_backup.tgz /opt/trains/data
     ```    
-        This backups all data to an archive in your home directory.
     
-        To restore this example backup, use the following command:

     $ sudo tar -xzf ~/trains_backup.tgz -C /opt/trains/data
     ```
+    </details>
 
-    3. Pull the new **trains-server** docker image using the following command:
+* Download the latest `docker-compose.yml` file, either [manually](https://raw.githubusercontent.com/allegroai/trains-server/master/docker-compose.yml) or execute:
 
     ```bash
-        $ sudo docker pull allegroai/trains:latest
+    $ curl https://raw.githubusercontent.com/allegroai/trains-server/master/docker-compose.yml -o docker-compose.yml 
     ```
 
-        If you wish to pull a different version, replace `latest` with the required version number, for example:
+* Spin up the docker containers, it will automatically pull the latest trains-server build    
 ```bash
-        $ sudo docker pull allegroai/trains:0.11.0
+$ docker-compose up -f docker-compose.yml
 ```
 
-    4. Launch the newly released Docker image (see [Launching Docker Containers](#launch-docker)).
