Developed by Daniele Procida, the Diataxis framework organizes technical documentation into four types: tutorials (learning-oriented), how-to guides (problem-oriented), explanations (understanding-oriented), and reference material (information-oriented). This separation aims to improve documentation quality by addressing different user needs and making information easier to find in the most suitable format.

Diataxis has gained popularity in recent years due to its clear, practical approach to organizing documentation. Technical writers and developers appreciate its user-centric focus and how it helps structure content for different needs. Its adoption by major tech companies and open-source projects has increased its visibility, while positive feedback from users experiencing better-organized docs has further fueled its growth in the tech community.
