As a free bonus to buyers of the print edition of the Ruby on Rails 3 Tutorial (as well as to anyone who buys any products directly from the Rails Tutorial website), I have made a special informal screencast on Haml, an awesome templating language that is a drop-in replacement for Embedded Ruby. The video runs nearly an hour and covers most of the basics of Haml, including installation, syntax, and even some gotchas.
Purchasers of the print edition should enter their contact information at the bonus screencast page, together with a piece of information whose answer appears in the book. Purchasers of the PDF or screencasts should check their email for a special message or check their original download page for a special link.
I hope you enjoy this bonus screencast!
