This guide is designed for beginners who want to get started with a Rails application from scratch. It does not assume that you have any prior experience with Rails. However, to get the most out of it, you need to have some prerequisites installed:
* The "Ruby":http://www.ruby-lang.org/en/downloads language version 1.8.7 or higher
+TIP: Note that Ruby 1.8.7 p248 and p249 has marshaling bugs that crash Rails 3.0.0. Ruby 1.9.1 outright segfaults on Rails 3.0.0, so if you want to use Rails 3 with 1.9.x, jump on 1.9.2 trunk for smooth sailing.
* The "RubyGems":http://rubyforge.org/frs/?group_id=126 packaging system
* A working installation of the "SQLite3 Database":http://www.sqlite.org
