What about:

------
Installing bailey.js requires you to have [node.js](http://nodejs.org/)
 and [node packet manager](https://www.npmjs.org/) installed. If you have
 those installed it is as simple as running the command below to install bailey.js globally:
```bash
$ npm install bailey -g
```

If you want to add it to your project dependecies run `npm install bailey --save`.
