Hey Adam,

You’ve seen the basics. Now, let’s apply them to a real-world use case. One of the best ways to understand the power of real-time is to build a simple chat application.

This hands-on tutorial walks you through, step-by-step:

• Initializing PubNub with your keys.
• Publishing messages from a user.
• Subscribing to a channel to receive messages.
• Displaying the chat in a simple UI.

It’s a practical exercise that covers the core concepts you'll use in more complex applications.
