+Providing a presistent `/data` mount is a good idea, both to persist the game world and to allow for the manual configuration which is sometimes needed.
+
+For instance, imagine a scenario when the initial launch has completed, but you now want to change the worldmap for your server.  
+
+Assuming you have a shared directory to your container, you can then (after first launch) drag and drop your premade maps or worlds into the `\worlds\` directory.  **Note:** each world should be placed in its own folder under the `\worlds\` directory.  
+
+Once your maps are in the proper path, you can then specify which map the server uses by changing the `level-name` value in `server.properties` to match the name of your map.
