Development resources

New to Ruby?

• tryruby.org Try ruby from the comfort of your browser. A nice tutorial to walk you through the basics of Ruby.
• [http://rubykoans.com/](Ruby Koans) Useful if you've seen Ruby before but want to stretch your wings a little.

New to Rails?

• [http://railsforzombies.org/](Rails for Zombies) An entertaining and effective tutorial to get you started in Rails.
• [http://ruby.railstutorial.org/ruby-on-rails-tutorial-book](Rails tutorial book) A fairly comprehensive walkthrough of what Rails has to offer.
• [http://pragprog.com/titles/rails4/agile-web-development-with-rails](The Rails Book) The canonical Rails book. Sadly, not available for free.

Once you're up and running

• Rails API This version is searchable and awesome. You can view it online or download your own bundle. I recommend the version with both Ruby and Rails included.
• Rails Guides Covers all the topics that are hard to learn from the API. My favorites are: Testing, Layouts and Rendering, Routing, and The Query Interface.

Rspec

The main docs page is here. I didn't find the 2-minute tutorial very useful, though. The good stuff is in the other links.

• Core for basic structure and subject stuff
• Expectations for "should" matchers
• Rails for Rails-specific stuff.
