I am building Setu, an open-source documentation template for developers, educators, and technical teams who want one site that works well for both human readers and AI systems. It uses Astro and Starlight to provide clean documentation pages, searchable navigation, Markdown/MDX authoring, AI-readable plain-text routes, and built-in interactive learning components like code playgrounds and quizzes. Setu is designed so anyone can start a professional documentation or learning site quickly, either from GitHub Template or with: npm create @rookduel/setu@latest my-site
