+##### Deployment
+
+```sh
+# compile to ES5
+1. npm build or gulp
+
+# upload dist/ to your server
+2. scp -rp dist/ user@dest:/path
+
+# install production dependencies only
+3. npm i --production
+
+# Use any process manager to start your services
+4. pm2 start index.js
+```
+
+In production you need to make sure your server is always up so you should ideally use any of the process manager recommended [here](http://expressjs.com/en/advanced/pm.html).
+We recommend [pm2](http://pm2.keymetrics.io/) as it has several useful features like it can be configured to auto-start your services if system is rebooted.

 ## Logging
 
 Universal logging library [winston](https://www.npmjs.com/package/winston) is used for logging. It has support for multiple transports.  A transport is essentially a storage device for your logs. Each instance of a winston logger can have multiple transports configured at different levels. For example, one may want error logs to be stored in a persistent remote location (like a database), but all logs output to the console or a local file. We just log to the console for simplicity, you can configure more transports as per your requirement.

 ## A Boilerplate-only Option
 
 If you would prefer not to use any of our tooling, delete the following files from the project: `package.json`, `gulpfile.babel.js`, `.eslintrc` and `.travis.yml`. You can now safely use the boilerplate with an alternative build-system or no build-system at all if you choose.
