About KDE

The KDE Human Interface Guidelines explain how to design apps that fit KDE Plasma and work outside it. They cover design philosophy and culture, common workflows and patterns, standard interface conventions, and platform integration, including layout, input, content display, text, icons, and accessibility. The site also includes formatting and style guidelines.

It focuses on what and why rather than implementation detail, so readers need component usage and API documentation and existing app source code for building components. The guidelines are not presented as strict rules and allow deviation when it produces a better result.
