+To build the library, you need to have Ruby and Rubygems installed. After that, run `gem install thor` and `gem install json_pure' to install the dependencies.
 
 To build a development version of the library, run `thor build:dev VERSION`, where VERSION is a string that can be anything you like. For example, using `thor build:dev core` will produce `kinetic-core.js`. To build a minified version of the library, run `thor build:prod VERSION`. If you want to add a release date other than the current day, use `-d="DATE"` (e.g. `-d="Mar 07 2012"`).
