+Now, this project is quite different. It's a cluster, of nodejs servers with a phantomjs executing as a moongose server (see the documentation of [phantomjs](http://www.phantomjs.org/)). This project use [Bull](https://github.com/OptimalBits/bull) as a internal job queue and [node-sidekiq](https://github.com/loopj/node-sidekiq) as a result queue.
