+# Contributing to MeliorStan
+
+Thank you for your interest in contributing to MeliorStan! This document provides guidelines and instructions for contributing to the project.

+- [Testing](#testing)
+
+## Development Setup
+
+### Prerequisites
+
+- PHP 8.3 or higher
+- Composer
+
+### Installation
+
+```bash
+git clone https://github.com/Orrison/MeliorStan.git
+cd MeliorStan
+composer install
+```
+
+### Available Commands
+
+| Command | Description |
+|---------|-------------|
+| `composer test` | Run all tests with paratest |
+| `composer format` | Auto-fix code style with PHP-CS-Fixer |
+| `composer analyze` | Run PHPStan analysis |
+
+## Project Architecture
+
+Each rule typically follows a consistent component structure as follows:
+
+```
+src/Rules/{RuleName}/
+├── {RuleName}Rule.php    # Main rule implementing Rule<NodeType>
+├── Config.php            # Configuration class (if rule has options)
+
+tests/Rules/{RuleName}/
+├── config/
+│   ├── default.neon      # Default configuration test
+│   └── {option}.neon     # Per-option configuration tests
+├── Fixture/
+│   └── ExampleClass.php  # Test fixtures
+├── DefaultTest.php       # Default configuration test
+└── {Option}Test.php      # Per-option tests
+```
+
+### Key Files
+
+| File | Purpose |
+|------|---------|
+| `config/extension.neon` | Central dependency injection & parameter schema definition |
+| `tests/Rules/*/config/*.neon` | Per-test configuration files that override defaults |
+| `tests/Rules/*/Fixture/*.php` | Test fixtures with various code patterns |
+
+## Adding New Rules
+
+1. Follow the established architecture pattern
+2. Include comprehensive tests
+3. Update documentation
+4. Ensure all checks pass: `composer format && composer analyze && composer test`
+
+## Testing
+
+### Running Tests
+
+```bash
+# Run all tests
+composer test
+
+# Run specific rule tests
+./vendor/bin/phpunit tests/Rules/{RuleName}/
+
+# Run a single test file
+./vendor/bin/phpunit tests/Rules/{RuleName}/DefaultTest.php
+```
+
+### Test Conventions
+
+- Each rule has multiple test classes covering all configuration combinations
+- Tests use exact line numbers from fixture files
+- **Always use error message constants** in test assertions, never hardcoded strings
+
+```php
+// ✓ Correct - using constants
+$this->analyse([__DIR__ . '/Fixture/Example.php'], [
+    [MyRule::ERROR_MESSAGE, 14],
+    [sprintf(MyRule::ERROR_MESSAGE_TEMPLATE, 'value', 3), 20],
+]);
+
+// ✗ Wrong - hardcoded strings
+$this->analyse([__DIR__ . '/Fixture/Example.php'], [
+    ['Some hardcoded error message.', 14],
+]);
+```
+
