title: How to read source code of Rails sample project?
body: <p>Reading source code of sample projects, such as Beast and Bort, are recommended as a good way to learn rails. But I found myself getting lost in reading source code of these projects, cause the included plugins might bring in some strange code without any hint, such as <code>"require"</code> or <code>"include"</code>. Could you share your rails code reading experience? Lots of thanks ahead.</p>
