Install the following software before installing the Game Closure DevKit:

Git (> 1.7.10) Node.js (> 0.8) Java —Will auto-install on OSX. Chrome

<- I Feel icky about running java. And Chrome does not support Java 7. Java 7 runs only on 64-bit browsers and Chrome is a 32-bit browser.

If you download Java 7, you will not be able to run Java content in Chrome and will need to use a 64-bit browser (such as Safari or Firefox) to run Java content within a browser. Additionally, installing Java 7 will disable the ability to use Apple Java 6 on your system. http://java.com/en/download/installed.jsp?detect=jre&try...
