+# Raygun for Expo demo project
+
+This is an [Expo](https://expo.dev) project created following the instructions in the root `README.md` file.
+
+## Running the project
+
+1. Change the API key in `app/index.tsx`:
+
+```tsx
+  const options: RaygunClientOptions = {
+    apiKey: "INSERT_YOUR_API_KEY_HERE",
+    version: "0.1.2",
+    enableCrashReporting: true,
+    logLevel: LogLevel.verbose,
+  };
+```
+
+2. Install dependencies
+
+   ```bash
+   npm install
+   ```
+
+3. Start the app
+
+   ```bash
+    npx expo start
+   ```
