John McCreesh has published a great new 30+ paged tutorials for getting started with Rails entitled Four Days on Rails.
Rails is well documented on-line; in fact, possibly too well documented for beginners, with over 30,000 words of on-line documentation in the format of a reference manual. What’s missing is a roadmap (railmap?) pointing to the key pages that you need to know to get up and running in Rails development… Four Days on Rails is designed to fill that gap.
McCreesh’s has his own site for the book, but I’ve also taken the liberty to do a mirror for the book.
