+# GitHub Actions and CI/CD Setup
+
+This repository is now configured with automated GitHub Actions workflows for continuous integration and deployment.
+
+## 🚀 Workflows
+
+### 1. CI/CD Pipeline (`.github/workflows/ci.yml`)
+- **Triggers**: Push to `main`/`develop`, Pull Requests to `main`
+- **Jobs**:
+  - Tests on Node.js 18.x and 20.x
+  - ESLint code quality checks
+  - TypeScript compilation
+  - Performance validation
+  - Build verification
+  - Automatic deployment to Firebase App Hosting (main branch only)
+
+### 2. Production Deployment (`.github/workflows/deploy.yml`)
+- **Triggers**: Release published, Manual dispatch
+- **Features**:
+  - Production-ready build validation
+  - Firebase App Hosting deployment
+  - Build artifacts verification
+  - Deployment notifications
+
+### 3. Pull Request Validation (`.github/workflows/pr-validation.yml`)
+- **Triggers**: PR opened/updated to `main`/`develop`
+- **Features**:
+  - Code quality checks
+  - Performance validation
+  - Bundle size analysis
+  - Security audit
+  - Lighthouse performance testing
+  - Automated PR comments with results
+
+## 🔧 Required Secrets
+
+Configure these secrets in your GitHub repository settings:
+
+### Firebase Deployment
+```
+FIREBASE_SERVICE_ACCOUNT    # Firebase service account JSON
+FIREBASE_PROJECT_ID         # Your Firebase project ID
+FIREBASE_TOKEN             # Firebase CI token
+```
+
+### Application Secrets
+```
+SENDGRID_API_KEY           # SendGrid API key for contact form
+LHCI_GITHUB_APP_TOKEN      # Lighthouse CI GitHub app token (optional)
+```
+
+## 📋 Setup Instructions
+
+### 1. Firebase Setup
+```bash
+# Install Firebase CLI
+npm install -g firebase-tools
+
+# Login to Firebase
+firebase login
+
+# Initialize project (if not already done)
+firebase init hosting
+
+# Get deployment token for CI
+firebase login:ci
+```
+
+### 2. Repository Secrets
+1. Go to Repository Settings → Secrets and Variables → Actions
+2. Add the required secrets listed above
+3. For `FIREBASE_SERVICE_ACCOUNT`:
+   - Go to Firebase Console → Project Settings → Service Accounts
+   - Generate new private key
+   - Copy the entire JSON content as the secret value
+
+### 3. Environment Configuration
+The workflows use these environment variables:
+- `NEXT_PUBLIC_SITE_URL`: Site URL (https://kodegas.com)
+- `NODE_ENV`: Environment (production/development)
+- `SENDGRID_API_KEY`: Email service configuration
+
+## 🔍 Monitoring
+
+### Build Status
+- Check the Actions tab in your GitHub repository
+- Green checkmarks indicate successful workflows
+- Red X marks indicate failures with detailed logs
+
+### Performance Monitoring
+- Lighthouse CI runs on every PR
+- Performance validation script ensures all optimizations are working
+- Bundle size analysis helps track application growth
+
+### Error Handling
+- Workflows include error handling and notifications
+- Failed deployments don't affect the live site
+- Rollback capabilities through Firebase Console
+
+## 🛠 Troubleshooting
+
+### Common Issues
+
+1. **Build Failures**
+   - Check Node.js version compatibility
+   - Verify all dependencies are installed
+   - Review TypeScript compilation errors
+
+2. **Deployment Failures**
+   - Verify Firebase project configuration
+   - Check service account permissions
+   - Ensure deployment token is valid
+
+3. **Performance Issues**
+   - Review Lighthouse CI reports
+   - Check bundle size increases
+   - Validate performance optimization features
+
+### Manual Deployment
+If automated deployment fails, you can deploy manually:
+```bash
+npm run build
+firebase deploy
+```
+
+## 📈 Performance Features Validated
+
+The CI/CD pipeline automatically validates these performance optimizations:
+- ✅ Error Boundary implementation
+- ✅ Performance Observer error handling
+- ✅ Resource loading optimization
+- ✅ Chunk loading error recovery
+- ✅ Error tracking and analytics
+- ✅ Bundle optimization
+- ✅ Component integration
+
+All workflows ensure these performance features continue working correctly with every code change.
