I'm fairly new to Mac OSx in general and I'm trying to go through the Jump Start Node.js book on a Mac. I've got node installed just fine and I'm at the part where I am supposed to edit the package.json file. I'm having some difficulty here. First, which package.json file am I supposed to edit? On my system I have several of these. Second, am I supposed to delete everything that's in the file and just put in what the book says or do I simply add the information provided in the book to the end of the file?

Any help would be greatly appreciated.
