A published Cirth docs site: section tabs, a sidebar, an article with an on-this-page outline, and search in the header

Every way in. One way live.

Write Markdown in the dashboard, or bring the docs you already have from GitHub — one run imports the lot. Either way it flows through one engine — rendered, kept as revisions, cached — and it's live in seconds. No build to run, no deploy to watch.

A real docs site, from plain Markdown.

Everything in this window is Cirth, running — the editor behind it, the published site it becomes, and the history under that. Flip through, then read what ships built in.
