+# OpenPad
+
+A mobile client for [OpenCode](https://opencode.ai) - the AI coding assistant. Built with Expo and React Native.
+
+## Features
+
+- Connect to any OpenCode server
+- View and manage chat sessions
+- Send messages and receive AI responses in real-time
+- View tool usage (file reads, edits, bash commands, etc.)
+- Expandable tool blocks with input/output details
+- Image attachment support
+- Dark/light theme support
+- Live polling for real-time updates
+
+## Screenshots
+
+*Coming soon*
+
+## Requirements
+
+- Bun 1.3+
+- iOS Simulator (Mac) or Android Emulator, or physical device with Expo Go
+
+## Installation
+
+This package is part of the shuvcode monorepo. From the repository root:
+
+```bash
+bun install
+```
+
+Start the development server:
+
+```bash
+bun run --cwd packages/mobile start
+```
+
+4. Run on your device:
+   - **iOS Simulator**: Press `i` in the terminal
+   - **Android Emulator**: Press `a` in the terminal
+   - **Physical Device**: Scan the QR code with Expo Go app
+
+## Connecting to OpenCode
+
+1. Make sure you have an OpenCode server running (default: `http://localhost:9034`)
+2. If running on a physical device, use your machine's local IP address instead of `localhost`
+3. Enter the server URL in the connect screen and tap "Connect"
