Human-first reading
Clear navigation, focused pages, search, and accessible presentation keep documentation useful to real people.
About Setu
Documentation infrastructure designed for two audiences.
An open-source, AI-ready documentation template built with Astro and Starlight. Setu gives maintainers a professional starting point without locking their content into a hosted platform or proprietary format.
Our approach
One complete foundation. Clear component boundaries.
Predictable AI access
Every document can expose stable plain-text output alongside a machine-readable discovery index.
Built-in interaction
Playgrounds and quizzes ship with Setu, ready for documentation or structured learning experiences.
Who Setu serves
A useful foundation across documentation and learning.
Setu is intentionally not tied to one industry or content model. Its structure supports teams that value clear ownership, portable content, and predictable publishing.
Product and engineering teams
Publish product documentation, architecture notes, integration guides, internal references, and operational knowledge from one maintainable codebase.
Educators and technical writers
Build structured lessons and tutorials, then introduce quizzes or playgrounds only where interaction improves understanding.
Open-source maintainers
Give contributors searchable documentation, transparent source files, reusable templates, and predictable contribution workflows.
Included foundation
The infrastructure needed before content can succeed.
Setu handles the repeatable publishing concerns so maintainers can spend more time improving the information itself.
- Markdown and MDX content that remains portable and version controlled
- Responsive navigation, search, theming, metadata, and static deployment
- Plain-text document endpoints and a machine-readable discovery index
- Built-in interactive playgrounds and knowledge-check quizzes
- A public-template workflow and one complete npm creation command
- Validation commands that protect content, builds, and internal links
Working model
Documentation as durable product infrastructure.
Own the source
Keep documentation beside the project, review it through Git, and deploy it using infrastructure your team controls.
Serve both audiences
Use the same content source for polished human-facing pages and stable AI-readable output.
Use interaction deliberately
Use the included learning-oriented components where they improve understanding and keep simpler pages focused.
