+Be respectful and inclusive. We welcome contributions from everyone.
+
+## Getting Started
+
+1. Fork the repository
+2. Clone your fork:
+   ```bash
+   git clone https://github.com/YOUR_USERNAME/agent-browser.git
+   cd agent-browser
+   ```
+3. Install dependencies:
+   ```bash

+   ```
+4. Build the project:
+   ```bash
+   pnpm run build
+   ```
+
+## Development Environment
+
+### Prerequisites
+
+- **Node.js** 20+ (we recommend using [nvm](https://github.com/nvm-sh/nvm))
+- **pnpm** (package manager)
+- **Rust** (for native CLI development)
+- **Chromium** (installed via `agent-browser install`)
+
+### Installing pnpm
+
+```bash
+npm install -g pnpm
+```
+
+### Installing Rust (for native CLI)
+
+```bash
+curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
+```
+
+### Project Structure

+
+### Running in Development
+
+```bash
+# Start the daemon in dev mode
+pnpm run dev
+
+# Run TypeScript compiler in watch mode
+pnpm run build --watch
+
+# Run tests in watch mode
+pnpm run test:watch
+```
+
+## Coding Style
+
+### TypeScript
+
+We use **Prettier** for code formatting. Run before committing:
+
+```bash
+pnpm run format
+```
+
+Check formatting without modifying:
+
+```bash
+pnpm run format:check
+```
+
+### General Guidelines
+
+- Use **TypeScript** for all new code
+- Add **JSDoc comments** for public APIs
+- Follow existing **naming conventions**
+- Keep functions **small and focused**
+- Write **tests** for new features
+
+### Commit Messages
+
+Follow [Conventional Commits](https://www.conventionalcommits.org/):
+
+```
+feat: add new command
+fix: resolve bug in snapshot
+docs: update README
+test: add tests for new feature
+refactor: improve code structure
+chore: update dependencies
+```
+
+## Testing
+
+We use **Vitest** for testing.
+
+### Run Tests
+
+```bash
+# Run all tests
+pnpm test
+
+# Run tests in watch mode
+pnpm run test:watch
+```
+
+### Writing Tests
+
+- Place test files in `test/` directory
+- Use `.test.ts` extension
+- Follow the existing test patterns
+
+Example:
+
+```typescript
+import { describe, it, expect } from 'vitest';
+
+describe('MyFeature', () => {
+  it('should work correctly', () => {
+    expect(true).toBe(true);
+  });
+});
+```
