A good way to understand code that is unclear is to experiment with it
and see what the effect is. If you don't understand why files are
there at all then remove them (or empty them) and see what stops
working. If you don't understand what a method call does then study
the docs and google, and again experiment with changing it and see the
effect. That way you will learn much more than simply having the
answer given to you.
Have you worked right through a tutorial such as railstutorial.org? I
am sure I have already suggested that.
