This book will guide you in creating a Rails application. It will focus on setting your system up properly and will fly a little lower than the typical 50,000 foot level of many tutorials.

We’re going to focus on Rails 3.1 (RC4 at the time of writing), highlighting some of the changes at 3.1 as we go. I’ll assume that you’re comfortable on the command line; that is, âcurlâ is more than a Canadian verb.
