In this chapter, we synthesized the knowledge of modules that we gained in Chapter 2 with the knowledge of the theme system from Chapter 3. We created a new module that provides a default theme.

In addition to this we worked with a simple custom content type and even made our first foray into the Drupal database API. At this point, we have a solid foundation for future module development.

In the upcoming chapters, we will start branching out, creating some more sophisticated modules. In the next chapter, we will continue developing the Philosophy Quotes module, integrating some sophisticated JavaScript and AJAX functionality. After that, we will turn to the administration interface, and create an administration module in Chapter 6. In Chapter 7, we will dive into the database API, creating a rich content type.
