+# CI/CD Automation Framework
+
+This document describes the complete CI/CD automation framework implemented for the Blog Link Analyzer browser extension.
+
+## Overview
+
+The automation framework provides:
+- **Continuous Integration**: Automated testing, linting, and type checking
+- **Continuous Deployment**: Automated building, packaging, and releasing
+- **Quality Assurance**: Security scanning, dependency management, and code quality checks
+- **Semantic Versioning**: Automated version bumping based on conventional commits
+
+## Architecture
+
+### GitHub Actions Workflows
+
+#### 1. Main CI/CD Pipeline (`.github/workflows/ci-cd.yml`)
+
+**Triggers:**
+- Push to `main` branch
+- Pull requests to `main` branch
+
+**Stages:**
+1. **Setup**: Node.js 20.x environment
+2. **Dependencies**: Install and cache dependencies
+3. **Quality Checks**:
+   - ESLint linting
+   - TypeScript type checking
+   - Jest unit testing
+4. **Security**: npm audit for vulnerabilities
+5. **Build**: Webpack production build
+6. **Test**: Extension integration tests
+7. **Package**: Create Chrome CRX and Firefox XPI packages
+8. **Upload**: Store artifacts for download
+
+#### 2. Semantic Release (`.github/workflows/semantic-release.yml`)
+
+**Triggers:**
+- Push to `main` branch after CI/CD completion
+
+**Features:**
+- Analyzes commit messages for conventional commit format
+- Automatically bumps version (patch, minor, major)
+- Creates GitHub releases with changelog
+- Publishes packages to releases
+
+### Configuration Files
+
+#### ESLint Configuration (`eslint.config.js`)
+
+**Modern Flat Config:**
+- File-specific global configurations
+- Separate configs for:
+  - Scripts and tests (Node.js environment)
+  - Extension files (browser environment)
+- Comprehensive ignore patterns for build artifacts
+
+#### Jest Configuration (`jest.config.js`)
+
+**Test Environment:**
+- Node.js test runner
+- Module name mapping for CSS and assets
+- Coverage collection
+- Support for both unit and integration tests
+
+#### Webpack Configuration (`webpack.config.js`)
+
+**ES Module Compatible:**
+- Production-optimized builds
+- Bundle size optimization
+- Asset management
+- Source maps for debugging
+
+### Automation Scripts
+
+#### Version Management (`scripts/version.sh`)
+
+**Features:**
+- Semantic version calculation
+- Manifest file updates
+- Git tagging
+- Version consistency checks
+
+#### Release Process (`scripts/release.sh`)
+
+**Stages:**
+1. Pre-deployment validation
+2. Clean build
+3. Package creation (Chrome & Firefox)
+4. Git tag and push
+5. GitHub release creation
+
+#### Pre-deployment Checks (`scripts/pre-deploy.sh`)
+
+**Validations:**
+- Manifest file integrity
+- Required files presence
+- Version consistency
+- Build artifact verification
+
+#### Extension Testing (`scripts/test-extension.js`)
+
+**Test Coverage:**
+- Manifest validation
+- Extension functionality
+- Content script injection
+- Popup interface
+- Browser compatibility
+
+### Git Hooks
+
+#### Pre-commit Hook (`.husky/pre-commit`)
+
+**Checks:**
+- ESLint linting
+- TypeScript type checking
+- Jest unit tests
+- Formatting validation
+
+#### Pre-push Hook (`.husky/pre-push`)
+
+**Validations:**
+- Full build process
+- Integration tests
+- Security audit
+- Package integrity
+
+## Usage
+
+### Local Development
+
+```bash
+# Install dependencies
+npm install
+
+# Run quality checks
+npm run lint          # ESLint
+npm run typecheck      # TypeScript
+npm test              # Jest tests
+
+# Build extension
+npm run build          # Production build
+
+# Test extension
+npm run test:extension # Integration tests
+
+# Create packages
+npm run package:chrome    # Chrome CRX
+npm run package:firefox   # Firefox XPI
+```
+
+### Release Process
+
+```bash
+# Automated release (recommended)
+git commit -m "feat: add new feature"
+git push origin main
+
+# Manual release
+npm run release
+```
+
+### Commit Convention
+
+Use conventional commits for automatic versioning:
+
+```
+feat: new feature
+fix: bug fix
+docs: documentation
+style: formatting
+refactor: code refactoring
+test: testing
+chore: maintenance
+```
