How to run this nodejs "express-remote" application?

I am running ubuntu and I am trying to control my totem functions via my mobile. I came across this application but I am not sure how to make it work !!

I have nodejs installed and I have already run the npm install command which did not return any errors.

The link below is the github page but unfortunately does not contain my documentation on how to use it.

https://github.com/yaacov/express-remote

The app.js require following modeles

var express = require('express');
var spawn = require('child_process').spawn;
var fs = require('fs');

1) first You need to go to command prompt, traverse to your project,

2) Then install these three modules in your project (express, child_process and fs),

3) Run the app.js with following command node app.js
