title: What does npm mean for socket.io/installing stuff?
body: <p>I'm a real noob at this. I've just began scratching the surface on node.js/socket.io/html5 and stuff. I finally figured out how to use my command prompt (using windows) to launch a "hello world" application with the command "node example.js." But what does <code>npm</code> mean? When I'm looking at socket.io it says to install, <code>npm install socket.io</code> Does that mean I need to extract all the files into my nodejs folder?</p>
  
  <p>I'm confused.</p>
