+
+Here are diagrams showing how to access Soul APIs when running standalone and how to expose a static client via extensions.

+
+## Steps
+
+In this guide, we will demonstrate how to host a static `React Admin` application.
+
+1. Create an `_extensions` folder and add an `api.js` file to it.:
+   ```sh
+     mkdir _extensions && touch _extensions/api.js
+   ```
+2. Add the following code to the `api.js` file:
+
+   ```js
+   const reactAdminApp = {
+     method: "GET",
+     path: "/api/client",
+     handler: (req, res, db) => {
+       const clientPath = path.join(__dirname, "../dist", "index.html");
+       res.app.use(express.static(path.join(__dirname, "../dist")));
+       res.sendFile(clientPath);
+     },
+   };
+   ```
+
+3. Build your React Admin client:
+
+   ```sh
+      npm run build
+   ```
+
+4. Copy the `dist` folder from your `React Admin` project to the `_extensions` folder:
+
+   ```sh
+    cp -r dist <path/to/_extensions>
+   ```
+
+5. Run your Soul application:
+   ```sh
+    soul -d foobar.db --extensions /path/to/_extensions/
+   ```
+6. To verify that the app is working, open the following URL in your browser:
+   ```
+    http://localhost:<port>/api/client
+   ```
