-# Welcome to your Expo app 👋
+# React Native Llama
 
-This is an [Expo](https://expo.dev) project created with [`create-expo-app`](https://www.npmjs.com/package/create-expo-app).

-## Get started
+A React Native mobile application for running LLaMA language models using ExecuTorch. This example is for iOS only for now.
 
-1. Install dependencies
+## Features
 
-   ```bash
-   npm install
-   ```
+- Run LLaMA models directly on device, build the UI using React Native
+- Tested using Llama 3.2 SpinQuant 1B on iPhone 12 Pro
 
-2. Start the app
 
-   ```bash
-    npx expo start
-   ```
+## Prerequisites
 
-In the output, you'll find options to open the app in a
+- Node.js & npm
+- Xcode
 
-- [development build](https://docs.expo.dev/develop/development-builds/introduction/)
-- [Android emulator](https://docs.expo.dev/workflow/android-studio-emulator/)
-- [iOS simulator](https://docs.expo.dev/workflow/ios-simulator/)
-- [Expo Go](https://expo.dev/go), a limited sandbox for trying out app development with Expo
+## Installation
 
-You can start developing by editing the files inside the **app** directory. This project uses [file-based routing](https://docs.expo.dev/router/introduction).
+1. Clone the repository: `git clone [email protected]:pytorch/executorch.git`
 
-## Get a fresh project
+2. Navigate to the root of the repository: `cd executorch`
 
-When you're ready, run:
+3. Install dependencies: `./install_requirements.sh --pybind xnnpack && ./examples/models/llama/install_requirements.sh`
 
-```bash
-npm run reset-project
-```
+4. Follow the instructions in the [README](https://github.com/pytorch/executorch/blob/main/examples/models/llama/README.md#option-a-download-and-export-llama32-1b3b-model) to export a model as `.pte`
 
-This command will move the starter code to the **app-example** directory and create a blank **app** directory where you can start developing.
+6. Navigate to the example: `cd examples/demo-apps/react-native/rnllama`
 
-## Learn more
+7. Install dependencies: `npm install`
 
-To learn more about developing your project with Expo, look at the following resources:
+8. Run the app: `npx expo run:ios --device` and select a USB connected iOS device

-- [Learn Expo tutorial](https://docs.expo.dev/tutorial/introduction/): Follow a step-by-step tutorial where you'll create a project that runs on Android, iOS, and the web.
+9. Find the device in finder, and place the exported `.pte` model and the downloaded tokenizer under the app.
 
-## Join the community
+10. Select the model and tokenizer in the app to start chatting:
