  Node.js (version >= 0.6.5)
  Coffeescript (version >= 1.1.3)
  socket.io (version >= 0.8.7)

  You can download node at: http://nodejs.org/#download
  You can install the npm modules with:
    $ npm install -g coffee-script socket.io

You can run it with

  Unix: $ bin/start.sh

script (see npm's documentation for where it puts installed modules).
