+# Development Guide
+
+## Quick Start
+
+1. **Install dependencies**:
+   ```bash
+   pnpm install
+   ```
+
+2. **Start development mode**:
+   ```bash
+   pnpm dev
+   ```
+   This watches for file changes and rebuilds automatically.
+
+3. **Load in Firefox**:
+   - Open `about:debugging#/runtime/this-firefox`
+   - Click "Load Temporary Add-on"
+   - Select `dist/manifest.json`
+
+4. **After making changes**:
+   - The extension rebuilds automatically in dev mode
+   - Click "Reload" in the Firefox debugging page
+
+## Development Workflow
+
+### Making Changes
+
+1. Edit source files in `src/`
+2. Run `pnpm build` or use `pnpm dev` (watch mode)
+3. Reload the extension in Firefox
+4. Test your changes
+
+### Adding New Features
+
+1. Create new service files in `src/services/`
+2. Add type definitions in `src/types/`
+3. Write tests in `src/tests/`
+4. Run `pnpm test` to verify
+5. Run `pnpm lint` to check code quality
+
+### Testing
+
+```bash
+# Run tests once
+pnpm test --run
+
+# Run tests in watch mode
+pnpm test
+
+# Run tests with UI
+pnpm test:ui
+```
+
+### Code Quality
+
+```bash
+# Check linting
+pnpm lint
+
+# Auto-fix linting issues
+pnpm lint:fix
+
+# Format code
+pnpm format
+
+# Check formatting
+pnpm format:check
+```
+
+## Debugging
+
+### Console Logs
+
+- **Background Script**: Check Browser Console (Ctrl+Shift+J)
+- **Content Script**: Check Web Console on the page (F12)
+- **Popup**: Right-click popup → Inspect
+
+### Common Issues
+
+1. **Extension not loading**: Check console for errors in manifest.json
+2. **Content script not running**: Check host_permissions in manifest
+3. **Storage not working**: Check permissions in manifest
+
+## Browser API Reference
+
+- [Firefox WebExtensions API](https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions)

+
+## Project Files
+
+### Core Files
+
+- `src/background.ts` - Handles storage and message passing
+- `src/content.ts` - Injects into web pages, handles form detection
+- `src/popup.ts` - Popup UI logic
+- `src/manifest.json` - Extension configuration
+
+### Services
+

+
+## 🚀 Getting Started
+
+### 1. Install Dependencies
+```bash
+pnpm install
+```
+
+### 2. Build the Extension
+```bash
+pnpm build
+```
+
+### 3. Load in Firefox
+
+1. Open Firefox and navigate to `about:debugging#/runtime/this-firefox`
+2. Click "Load Temporary Add-on"
+3. Navigate to the `dist` folder in your project
+4. Select the `manifest.json` file
+5. The extension will be loaded!
+
+### 4. Test the Extension
+
+1. Click the JobSpeed icon in your browser toolbar
+2. Upload a resume file
+3. Navigate to a job application page (e.g., LinkedIn, Indeed, company career pages)
+4. Click "Scan Current Page" in the popup
+5. Review the suggested field mappings in the preview panel
+6. Click "Apply Auto-fill" to fill the form
+
+## 🧪 Testing
+
+The project includes comprehensive unit tests for the field matching logic:
+
+```bash
+pnpm test --run
+```
+
+All 8 tests pass:
+- ✓ Full name field matching
+- ✓ Email field matching  
+- ✓ Phone field matching
+- ✓ Company field matching
+- ✓ First name field matching
+- ✓ Last name field matching
+- ✓ Empty value handling
+- ✓ Multiple field matching
+
+## 📦 Build Output
+
+The `dist/` folder contains:
+- `manifest.json` - Extension manifest
+- `background.js` - Background service worker
+- `content.js` - Content script
+- `popup.html`, `popup.js`, `popup.css` - Popup UI
+- `icons/` - Extension icons
+
+## 🔒 Privacy & Security
+
+- All data stored locally in browser storage
+- No external servers or data transmission
+- User has full control over their data
+- Can clear resume data anytime
+
+## 🎨 Code Quality
+
+- **TypeScript Strict Mode**: Enabled with comprehensive type checking
+- **ESLint**: Configured with TypeScript-specific rules
+- **Prettier**: Consistent code formatting
+- **No Linting Errors**: All code passes strict linting
+- **All Tests Passing**: 100% test success rate
+
+## 🔧 Architecture
+
+### Service Layer
+- **FormDetector**: Scans and identifies form fields on web pages
+- **FieldMatcher**: Intelligent matching of resume data to form fields
+
+### Storage
+- Uses Firefox's `browser.storage.local` API
+- Stores parsed resume data as JSON
+- Tracks last update timestamp
+
+### Messaging
+- Background script handles storage operations
+- Content script manages page interaction
+- Popup communicates with both via message passing
+
+## 📚 Next Steps
+
+To enhance the extension further, consider:
+
+1. **Better Resume Parsing**: 
+   - Integrate with a resume parsing API
+   - Support more file formats
+   - Extract structured data more accurately
+
+2. **Field Mapping Intelligence**:
+   - Machine learning for better field detection
+   - Learn from user corrections
+   - Support multi-page forms
+
+3. **UI Enhancements**:
+   - Edit resume data in the popup
+   - Multiple resume profiles
+   - Field-by-field manual override
+
+4. **Browser Support**:
+   - Add Chrome support
+   - Add Edge support
+   - Build cross-browser package
+
+5. **Advanced Features**:
+   - Save form drafts
+   - Auto-detect job application pages
+   - Keyboard shortcuts
+
+## 🐛 Known Limitations
+
+- Basic resume parser (extracts email, phone, skills)
+- Works best with standard HTML forms
+- May not work with heavily customized React/Vue forms
+- Icons are simple SVG placeholders
