+- You don't need to modify anything from your code to be able to use this nifty feature.
 - In your application the environment variable `NODE_APP_INSTANCE` is exposed so you can listen for different port if needed. (e.g .listen(8000 + process.env.NODE_APP_INSTANCE))
 - Be sure your **application is stateless** meaning that there is not any local data stored in the process, like sessions/websocket connections etc. Use Redis, Mongo or other DB to share states between processes
