 This guide is designed for beginners who want to get started with a Refinery CMS site from scratch. It does not assume that you have any prior experience with Refinery. 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 (1.9.3 recommended)
+* The "Ruby":http://www.ruby-lang.org/en/downloads language version 1.9.3 or higher
 
 TIP: Do not use Ruby 1.9.1 as Rails 3.x is not compatible with it. Use 1.9.3 for smooth sailing.
