In this chapter, we have learned what taxonomy is, and we have learned the difference between taxonomy terms and taxonomy vocabularies in Drupal. After that, we learned how to create vocabularies and add terms to vocabularies using the Drupal web user interface. Then, we learned how to add term references to content types, and to categorize content using the term reference we created. Finally, we examined how to add fields to vocabulary terms, and explored its potential use.
The next chapter will be a fun chapter because we will learn how to attach files and images to content using the File and Image fields in Drupal, which makes the current text-only website more fun and eye-catching.
