Introduction

Facebook apps are just websites with a few extra features. They're displayed on Facebook pages in an iframe. You'll use the same technologies you use to build web pages to build your Facebook app. For this book, I made a few assumptions. You should already know how to create, edit, and manage files and you should have a basic understanding of HTML and JavaScript. Some PHP knowledge is also helpful but you can get by without it.

Facebook does not host your app for you; you'll need a web host to serve your files from. You'll need a working directory and you'll need to know how to upload files so that they're available online.

I'll walk you through the basic app setup process and then walk through some of the extra details and features that Facebook provides.
