At this point, you have a functioning server-side component and functioning clients, so it's time to see them working together, sending messages back and forth, and letting you get a good game of Pong in before lunchtime. Ready?

Your server component may already be running. If not, restart the Prosody service using the following command:

sudo service prosody start

Run the component from the pong-component directory:

node index.js

For the clients, open a second terminal window, navigate to the directory with the client's index.js code and run that (node index.js), then open a browser and visit http://localhost:3000.

You may want to open a second browser, also point it to http://localhost:3000, and get your own one-on-one Pong game going.
