Like most Ruby on Rails applications, Racing on Rails has a long list of prerequisites. However, they are typical Rails prerequsites, so if you are already developing with Ruby on Rails, you may already have them installed. Also consider all-in-one Rails installers for Windows and Mac OS X, Free BSD Ports, or Linux packages.

• MySQL 4.1+
• Ruby 1.8+
• Ruby Gems
• MySQL gem (optional) http://tmtm.org/downloads/mysql/ruby/ or gem install mysql
• PDF::Writer gem + dependencies http://ruby-pdf.rubyforge.org/pdf-writer/ or gem install pdf-writer
• Ruby on Rails 2.0 for last release, Ruby on Rails 2.1.1 for trunk
• Subversion (optional)
• Capistrano (optional)

Racing on Rails is developed and tested on MySQL 5.1, but any modern version should work. In fact, it should run on any Rails-supported database with few changes.

If you install Rails as a Ruby gem, install all the dependencies (e.g., Rake) as well.

Subversion is a source control tool useful for production deployments and working on Racing on Rails itself.

Capistrano is an automated Rails deployment tool. It's a good way to do handle your production deployments. If you install Capistrano, you'll want the its prerequisites as well.
