We will be building the application by modifying four files included in the tutorial folder:

* *paths.js*: This file contains the system dependent paths that are needed for the various elements of the tutorial to work correctly.
* *server.js*: This file is the main entry point for our *Node.js* application
* *spawner.js*: This file will contain the main class for our Stream Cache Server application
* *public/index.html*: This file will act as the front end for our application. It will contain the User interface for creating, removing, and monitoring web viewers.

View the content in the directory *server_tutorial/complete* to see what your project should contain once you have finished this tutorial.
