In this chapter, we introduced some of the key ideas for extending Drupal using some example community or contrib modules that were published on the drupal.org website.

We covered improving the FAQs page by installing a Views format plugin that enabled us to present the FAQs as "accordions".

We also covered the use of a couple of key real-life build tools, notably the Pathauto and Token modules, to provide us with SEO- and human-friendly URL aliases.
