+# Backstage UI Workspace
 
-This is your newly scaffolded Backstage App, Good Luck!
+> **Work in progress** — this workspace is not yet in use and should not be considered stable or production-ready.
 
-To start the app, run:
+This is a standalone [Yarn workspace](https://yarnpkg.com/features/workspaces) that will house the Backstage UI library packages. It is being set up as a fully isolated workspace within the Backstage monorepo, with its own dependency tree, lockfile, and tooling configuration, independent of the root workspace.
 
-```sh
-yarn install
-yarn start
-```
+The goal is to allow the UI packages to be developed, tested, and released independently from the rest of the monorepo.
