Use a single http server

[kmturley]

In your documentation you explain running
node ./server.js

Then running:
python -m SimpleHTTPServer

or
http-server

In fact you are already have a node http server running you can use to server the files. Simple change server.js to server static files via the handler:

function handler (req, res) {
  if (req.url === '/') {
    req.url = '/index.html';
  }
  console.log('handler', req.url);
  fs.readFile(__dirname + '/src' +  req.url, function (err,data) {
    if (err) {
      res.writeHead(404);
      res.end(JSON.stringify(err));
      return;
    }
    res.writeHead(200);
    res.end(data);
  });
}

Now both Socket.io and the http server will be running on the same address and port
