Using HTML in a Sugar Activity is not new. The Wikipedia Activity has been embedding HTML contents for years. It does this by integrating into the Activity two things: the Sugar browser to render HTML and an HTTP server to react to user clicks by calling Python code.
To learn more on how to Develop Sugar Activities Using HTML5 read the new chapter on the How to Develop your Sugar Activities Manual.

Copy this book! We hope you will. I am proud to say that through a collaboration with One Laptop per Child, Sugar Labs and FLOSS Manuals, a print and online manual about using the XO laptop and Sugar operating system is now available as via print-on-demand at Lulu.com.  Tom Brady checked it out when he was visiting the office last week and thought it was pretty neat.
You can order your own print copy for a modest price – someone walks off with one of mine every week, and I’m due to order some more. Or you can read it on your XO laptop - the PDF is always available for free and for remixing into your own works. Soon, the book will be for sale on Amazon as well.
Two sides of an elegant book
The OLPC Laptop Guide has a simple, clean cover design and the content inside was written by a community of professional writers, editors, open source experts, and OLPC staff. This book contains 240 pages of how-to information for your XO laptop and the operating system that kids love, Sugar. This book was written by a group of people in the unique wiki tool offered by FLOSS Manuals. Much of the content was written in a five-day collaborative BookSprint. In it you’ll find instructions for connecting with and caring for this unique little laptop. The neat thing is, once you’re done with a real book, you can pass it on to the next person who wants to learn about their XO. Get a book and pass it on.
