Overview of this book

This book is designed for readers who learn by doing and employs many examples and screenshots to let the reader dig in and start coding.

When you have completed this book, you will fully understand how the template system works, how to extend it when you have specialized needs, and how to optimize the performance and usability of your content. This book is for web developers and template authors who want to fully understand and utilize the Django template system. The reader should have completed the introductory tutorials on the Django project's website and some experience with the framework will be very helpful.
