+# `create-react-admin`
+
+This CLI generates a new react-admin application using [Vite](https://vitejs.dev/). Use it by running the following command:
+
+```sh
+npx create react-admin@latest your-admin-name
+# or
+yarn create react-admin your-admin-name
+```
+
+It will then ask you to choose:
+- a data provider
+- a auth provider
+- the names of the resources to add
+- the package manager to use to install the dependencies
