	The most popular example used to explain the Decorator pattern in Ruby is an example involving a Coffee class, of which there are various subclasses of coffee that can have various additional ingredients (milk, sugar, etc.). For many of the sites, they mentioned using the "Head First Design Patterns" book as a source, so of course we recommend the same <ref name="head_first"></ref>. The biggest disadvantage to using this resource is that it is a part of a textbook so is rather lengthy. There are a variety of sites devoted to explaining this pattern (most of which use the Coffee example) but a few stood out as especially useful in various ways. One of the better resources for any project is someone that has used the pattern before and blogs are a great place to start. One blog in particular gives a great explanation of the Decorator pattern being used in the Coffee example <ref name="8lines"> http://lukeredpath.co.uk/blog/decorator-pattern-with-ruby-in-8-lines.html - 2006</ref>. This is one of the sources that explicitly mentioned using the "Head First Design Patterns" book, so it may be easy to use these resources in parallel.

	Another useful resource for implementing the Decorator pattern in Ruby written by another developer is on the site Programming = Fun <ref name="decorators"> http://kresimirbojcic.com/2011/12/01/decorators-in-ruby.html -2011 </ref>. One advantage this source has over the previous is that it is more up to date so it is less likely that there will be conflicting information with current knowledge and technology. This site uses the same coffee example but does not mention using the book so this may threaten how valid their interpretation is. Although they are both also about the same length, it seems that this one is more detailed in explaining what they did and why as they present the relevant code snippets.
