How do I configure OpsWorks to deploy a not-officially-supported version of Node.js?

I am trying to set up an OpsWorks stack to with a Node.js layer that uses the latest version of Node (4.1.1). I am fairly new to Chef and I am not sure where in the cookbooks repo I would need to make changes to pull down and install Node 4.1.1, instead of their default which is 0.12.7.

Any help is appreciated.
