Chapter 3: Introduction to Rails
This chapter will serve as an introduction to the various parts of the Rails framework. Because Rails is loosely coupled, it makes sense to introduce the parts by themselves, and then describe how to fit them together.
Chapter 4: Store Administration
This chapter will walk you through the first part of the Shoplet application. It will be a fairly detailed look at most of the code necessary, and as such will give you a good overview of what's required to create a Rails application from scratch.
