As a WordPress plugin, WP Ultimo is an absolute monster in terms of sheer size and complexity. The codebase is huge – specially when compared with simpler plugins – in all metrics, from line count to bytes.

As a developer working on extending WP Ultimo, it might be difficult to find what you need inside that pesky folder, or to understand why something is happening in a particular way.

Fear not! There is a very systematic logic behind the appearance of chaos.

The goal of this course is to give you an overview of the WP Ultimo structure, its core components, and its lifecycle. We’ll also explain why some technical decisions were made when choosing how to implement some of the elements inside.
