this is a resounding boon. However, the cluster module is still in experimental stage, therefore it should only be used after understanding its purpose and behavior. To use it, simply run `node cluster_app.js`. **Its use is completely optional and `app.js` is not tied in any way to it**. As a reminder, if you plan to use `cluster_app.js` instead of `app.js`, be sure to indicate that in `Procfile` if you are deploying your app to Heroku. this is a resounding boon.

### I am getting MongoDB Connection Error, how do I fix it?
That's a custom error message defined in `app.js` to indicate that there was a connection problem to MongoDB:
```
mongoose.connection.on('error', function() {
console.log('✗ MongoDB Connection Error. Please make sure MongoDB is running.'.red);
});
```
As the messages implies, you need to have a MongoDB server running before launching `app.js`. You can get MongoDB from
[mongodb.org/downloads](mongodb.org/downloads), or install it via a package manager
([Homebrew](http://brew.sh/) on Mac, `apt-get` on Ubuntu, `yum` on Fedora, etc.)
### Why Jade and not Handlebars template engine? ### Why Jade and not Handlebars template engine?
When I first started this project I didn't have any experience with Handlebars. Since then I have worked on Ember.js apps and got myself familiar with the Handlebars syntax. While it is true Handlebars is easier, because it looks like good old HTML, I have no regrets picking Jade over Handlebars. First off, it's the default template engine in Express, so someone who has built Express apps in the past already knows it. Secondly, I find `extends` and `block` to be indispensable, which as far as I know, Handlebars does not have out of the box. And lastly, subjectively speaking, Jade looks much cleaner and shorter than Handlebars, or any non-HAML style for that matter.
