Hugo websites have handled many use cases, some of which are more complicated than the examples discussed in this book. The core features of Hugo, such as page bundles, taxonomies, and its template lookup order, form the building blocks of any Hugo-based website.

There are features within Hugo that enable advanced functionality as well as modern web development practices that can make our websites faster and more complete. In this chapter, we will go over some of the obscure features of Hugo and the Jamstack, which are essential to complete and maintain a modern website.
