+# Contributing to PHP/Laravel Security Linter
+
+Thank you for your interest in contributing to this project! This document provides guidelines and instructions for contributing.
+
+## Code of Conduct
+
+Please be respectful and constructive in all interactions. We welcome contributors of all experience levels.
+
+## How to Contribute
+
+### Reporting Bugs
+
+1. Check if the issue already exists in [GitHub Issues](https://github.com/security-linter/php-laravel/issues)
+2. If not, create a new issue with:
+   - Clear description of the problem
+   - Steps to reproduce
+   - Expected vs actual behavior
+   - PHP/Laravel versions
+   - Sample code that triggers the issue
+
+### Reporting False Positives/Negatives
+
+Security linters can produce false positives (safe code flagged as vulnerable) or false negatives (vulnerable code not detected). Please report these with:
+- The code snippet being analyzed
+- Why you believe it's a false positive/negative
+- Any relevant context
+
+### Suggesting Features
+
+1. Check existing issues and discussions
+2. Create a new issue describing:
+   - The vulnerability type you want to detect
+   - Example vulnerable and safe code patterns
+   - References to security documentation (CWE, OWASP, etc.)
+
+### Pull Requests
+
+1. Fork the repository
+2. Create a feature branch: `git checkout -b feature/your-feature-name`
+3. Make your changes
+4. Test your changes
+5. Commit with clear messages
+6. Push and create a Pull Request
+
+## Development Setup
+
+### Requirements
+
+- PHP 8.1+
+- Composer
+
+### Installation
+
+```bash
+git clone https://github.com/security-linter/php-laravel.git
+cd php-laravel
+composer install
+```
+
+### Running the Linter
+
+```bash
+# Analyze a file
+php bin/security-lint path/to/file.php
+
+# Analyze a directory
+php bin/security-lint path/to/directory/
+```
+

+
+## Adding New Detection Rules
+
+### 1. Create a New Rule Class
+
+Create a new file in `src/Rules/`:
+
+```php
+<?php
+
+namespace SecurityLinter\Rules;
+
+use PhpParser\Node;
+use SecurityLinter\Report\Vulnerability;
+
+class YourNewRule extends AbstractRule
+{
+    protected string $name = 'your_rule';
+
+    public function analyze(Node $node, string $file, array $context = []): array
+    {
+        $vulnerabilities = [];
+
+        // Your detection logic here
+
+        return $vulnerabilities;
+    }
+}
+```
+
+### 2. Register the Rule
+
+Add your rule to `SecurityLinter.php`:
+
+```php
+private function registerDefaultRules(): void
+{
+    $this->rules = [
+        // ... existing rules
+        new YourNewRule(),
+    ];
+}
+```
+
+### 3. Add Messages
+
+Add messages in `src/I18n/Messages.php` for both Japanese and English:
+
+```php
+// Japanese
+'your_rule.name' => 'ルール名',
+'your_rule.vulnerability_message' => '脆弱性の説明...',
+
+// English
+'your_rule.name' => 'Rule Name',
+'your_rule.vulnerability_message' => 'Vulnerability description...',
+```
+
+### 4. Update Documentation
+
+- Add detection patterns to `docs/DETECTION_RULES.md`
+- Update README.md if needed
+
+## Testing
+
+### Manual Testing
+
+Create test files in `test-samples/` to verify detection:
+
+```php
+<?php
+// test-samples/your-test.php
+
+// VULNERABLE: Should be detected
+vulnerable_pattern();
+
+// SAFE: Should not be detected
+safe_pattern();
+```
+
+Run the linter against your test files:
+
+```bash
+php bin/security-lint test-samples/your-test.php -c
+```
+
+## Commit Guidelines
+
+- Use clear, descriptive commit messages
+- Reference issue numbers when applicable
+- Keep commits focused on single changes
+
+Example:
+```
+Add detection for insecure deserialization
+
+- Detect unserialize() with allowed_classes => true
+- Add messages in Japanese and English
+- Update DETECTION_RULES.md
+
+Fixes #123
+```
