This chapter is probably the most technically challenging chapter that you'll read in this book, but read it with the objective of getting a basic understanding of Zope 3 and the moving parts you'll need to know about. You'll generally need to only understand where to find the pieces you require, where to put them, and how to tie them together, and that will come after this introduction to the general concepts.
As part of this chapter, we'll cover how images, stylesheets, and templates can be exposed as Zope 3 browser resources, instead of being used as "old school" skin layers, as discussed in the previous chapter. We'll also cover some of the jargon-y terms that you'll need to know about but not understand in depth.
