+
+        Install both the expo plugin in your server and both the Better Auth package and the Expo plugin in your Expo app.
+
+        ```package-install
+        @better-auth/expo
+        ```

+        ## Add the Expo Plugin on Your Server
+
+        Add the Expo plugin to your Better Auth server.
+
+        ```ts title="server.ts"
+        import { betterAuth } from 'better-auth';
+        import { expo } from '@better-auth/expo';

+        ## Initialize Better Auth Client
+        
+        To initialize Better Auth in your Expo app, you need to call `createAuthClient` with the base url of your Better Auth backend. Make sure to import the client from `/react`.
+
+        ```ts title="src/auth-client.ts"
+        import { createAuthClient } from 'better-auth/react';
+
+        const authClient = createAuthClient({
+            basURL: 'http://localhost:8081', /* base url of your Better Auth backend. */
+        });
+        ```
+        <Callout>
+         Be sure to include the full URL, including the path, if you've changed the default path from `/api/auth`.

         ## Scheme and Trusted Origins
 
         Better Auth uses deep links to redirect users back to your app after authentication. To enable this, you need to add your app's scheme to the `trustedOrigins` list in your Better Auth config.
