npm is the Node Package Manager. I think it's assumed that if you've been working with Node.js (or other things in its family, like CoffeeScript), you've already downloaded npm. It's like when a Python framework says "Just use pip install!" or a Ruby project says "Download our gem!" That said, they really should have more info before dropping you on the install page.
