 # Refract Docs
 
+> **This repository has moved.** The documentation source is now
+> [`apps/docs`](https://github.com/refract-org/refract/tree/main/apps/docs) in
+> [refract-org/refract](https://github.com/refract-org/refract), imported with
+> its full history, and the site is published at
+> [refract-org.github.io/refract](https://refract-org.github.io/refract/).
+> Open issues and pull requests there. This repository publishes only redirects:
+> each page under `refract-org.github.io/refract-docs/` sends you to the same
+> page at the new address (see `redirects.mjs`).
+
 Public documentation for [Refract](https://github.com/refract-org/refract), a deterministic observation engine for public revision histories.

+// Turns the built site in dist/ into a redirect-only site.

+// The documentation now lives in the refract repository (apps/docs) and is
+// published at https://refract-org.github.io/refract/. Run after
+// `npm run build`: every page under /refract-docs/ is replaced by one that
+// sends the reader to the same page at the new address, keeping any query and
+// fragment. Everything that is not a page (images, the notebook, the sitemap)
+// stays where it was, so a link straight to an image keeps working. 404.html
+// catches any other path, which GitHub Pages serves for a missing one.
