+## :rocket: Deploy
+
+This project is continuously deployed to [Heroku](http://voxel-rsr.herokuapp.com/dist) using a [NodeJS](https://github.com/heroku/heroku-buildpack-nodejs) [buildpack](https://devcenter.heroku.com/articles/buildpacks) by [Travis](https://travis-ci.org/rishabhsrao/remember), whenever a new tag is pushed. This should be configured **only once** using the [Heroku toolbelt](https://toolbelt.heroku.com):
+
+```
+heroku create voxel-rsr
+git push heroku master
+heroku ps:scale web=1
+heroku config:set BUILDPACK_URL=https://github.com/heroku/heroku-buildpack-nodejs#v75 --app voxel-rsr
+```
+
+:tophat: **Tip** The `heroku ps:scale web=1` will spin up a [dyno](https://devcenter.heroku.com/articles/dynos) under the [free](https://blog.heroku.com/archives/2015/5/7/heroku-free-dynos) plan.
+:tophat: **Tip** The `#75` above is the [release tag](https://github.com/heroku/heroku-buildpack-nodejs/releases) for the project. Use the latest tag for best results.
+:tophat: **Tip** The non-minified version of this project is also deployed to [Heroku at /app](http://voxel-rsr.herokuapp.com/app).
