+# Plone on React Router 7
+
+This is a proof of concept of a [React Router](https://reactrouter.com/dev/docs) app, using the `@plone/*` libraries.
+This is intended to serve as both a playground for the development of both packages and as a demo of Plone using Remix.
+
+> [!WARNING]
+> This package or app is experimental.
+> The community offers no support whatsoever for it.
+> Breaking changes may occur without notice.
+
+## Development
+
+To start, from the root of the monorepo:
+
+```shell
+pnpm install
+pnpm --filter plone-remix run dev
+```
+
+Then start the Plone backend:
+
+% TODO MAKEFILE
+```shell
+make backend-docker-start
+```
+
