+# Contributing to Cognitive Code Analysis
+
+Thank you for your interest in contributing to this project! 💙
+We welcome all improvements, whether they're bug fixes, new features, documentation updates, or test enhancements.
+
+---
+
+## 🧭 Contribution Guidelines
+
+### 1. Fork and Branch
+
+Fork the repository and create a new branch for your work:
+
+```bash
+git checkout -b feature/your-feature-name
+```
+
+### 2. Write Clear Commits
+
+- Use clear, atomic commits that explain **what** and **why**, not just how
+- Follow [Conventional Commits](https://www.conventionalcommits.org/) when possible
+- Example: `feat: add code coverage display to cognitive metrics command`
+
+### 3. Include Tests
+
+**All Pull Requests must include tests.**
+
+- **New features**: Must include unit or integration tests
+- **Bug fixes**: Must include regression tests reproducing the original issue
+- **Refactoring**: Ensure existing tests pass and add new tests if coverage gaps exist
+
+If you're fixing an open issue, reference it in your PR description and ensure the issue scenario is covered by a test.
+
+### 4. Code Quality Standards
+
+Run these checks before submitting your PR:
+
+```bash
+# PHPStan - Static Analysis (must pass with no errors)
+./bin/phpstan analyse
+
+# PHPMD - Code Quality Analysis
+composer phpmd
+
+# PHPUnit - All tests must pass
+./bin/phpunit
+
+# Code Coverage (optional but encouraged)
+XDEBUG_MODE=coverage ./bin/phpunit --coverage-clover=coverage-clover.xml
+```
+
+**Code Style:**
+- Follow PSR-12 coding standards
+- Use strict types: `declare(strict_types=1);`
+- Add type hints to all parameters and return types
+- Use PHPDoc blocks for complex array types and additional context
+
+### 5. Documentation
+
+Update documentation when relevant:
+
+- Update `README.md` for user-facing feature changes
+- Add or update PHPDoc blocks for new classes and methods
+- Include inline comments when logic isn't immediately obvious
+- Update configuration examples if you add new options
+
+---
+
