Customizing the Simple CMS

The simple CMS you put together in the last chapter is already in pretty good shape; it's something that most developers wouldn't mind showing to clients as an initial prototype, for example. But so far, it uses just a few stock applications bundled with Django and doesn't offer any extra features on top of that. In this chapter, you'll see how to take this simple project as a foundation and start adding your own customizations, like rich-text editing in the admin and a search system for quickly finding particular pages.
