+Expo is a popular framework for building cross-platform apps with React Native. Better Auth supports both Expo native and web apps.
 
 ## Installation
 
-First we need to install Better Auth main packge on both Expo and Our Server.
+<Steps>
+    <Step>
+        ## Configure A Better Auth Backend
+        Before using Better Auth with Expo, make sure you have a Better Auth backend set up. You can either use a separate server or leverage Expo's new [API Routes](https://docs.expo.dev/router/reference/api-routes) feature to host your Better Auth instance.
+
+        To get started, check out our [installation](/docs/installation) guide for setting up Better Auth on your server.
+    </Step>
+    <Step>
+        ## Install Better Auth and Expo Plugin
+
+        With your server up and running, install both Better Auth and the Expo plugin in your Expo project.
+
+        ```package-install
+        better-auth @better-auth/expo
+        ```
+    </Step>
+    <Step>
+        ## 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`.
+        </Callout>
+    </Step>
+    <Step>
+        ## Configure Metro Bundler
+
+        To resolve better auth exports you'll need to enable `unstable_enablePackageExports` in your metro config. 
+
+        ```js title="metro.config.js"
+        const { getDefaultConfig } = require("expo/metro-config");
+
+        const config = getDefaultConfig(__dirname)
+
+        config.resolver.unstable_enablePackageExports = true; // [!code highlight]
+
+        module.exports = config;
+        ```
+    </Step>
+</Steps>
 
-```package-install
-install better-auth
-```
 
-Then we need to install the Expo plugin.
 
-```package-install
-install @betterauth/expo
-```
