+# Experimental Schema Explorer workspace
+
+This is a self-contained pnpm and Cargo workspace. It does not register
+packages, scripts, catalogs, or dependencies in the repository's main `ui`
+workspace and does not add features to existing Rust crates.
+
+The workspace consumes existing code through dependencies:
+
+- `schema-viewer` links to the generated `@quent/schema` TypeScript package.
+- `yaml-wasm` depends on the existing `quent-yaml` and `quent-schema` crates.
+- `schema-explorer` depends on the local `schema-viewer` package.
+
+From the repository root:
+
+```sh
+pixi run --frozen pnpm --dir experimental/vibe/ui install --frozen-lockfile
+pixi run --frozen pnpm --dir experimental/vibe/ui schema:ci
+pixi run --frozen pnpm --dir experimental/vibe/ui explorer
+```
+
+The explorer is normally available at `http://localhost:5173`.
