+# Contributing to LN1
+
+## Overview
+
+Thank you for your interest in contributing to the LN1 (Legalese Node) project. This document provides guidelines for contributing to the development of LN1's decentralized legal intelligence infrastructure.
+
+## Development Process
+
+### Branch Strategy
+
+```bash
+# Feature development
+git checkout -b feature/your-feature-name
+
+# Bug fixes
+git checkout -b fix/bug-description
+
+# Documentation updates
+git checkout -b docs/update-description
+```
+
+### Commit Guidelines
+
+Use conventional commit messages:
+
+- `feat:` New features
+- `fix:` Bug fixes
+- `docs:` Documentation changes
+- `test:` Test additions or modifications
+- `refactor:` Code refactoring
+- `style:` Code style changes
+- `chore:` Maintenance tasks
+
+## Code Standards
+
+### Python Code Style
+
+```python
+# Example of proper code style
+class DocumentProcessor:
+    """
+    Process legal documents according to LN1 standards.
+    """
+    def __init__(self):
+        self.validator = DocumentValidator()
+        self.indexer = DocumentIndexer()
+
+    async def process_document(self, document: Document) -> ProcessedDocument:
+        """
+        Process a single document through the validation pipeline.
+        
+        Args:
+            document (Document): Input document
+            
+        Returns:
+            ProcessedDocument: Processed and validated document
+        """
+        validated = await self.validator.validate(document)
+        return await self.indexer.index(validated)
+```
+
+### Solidity Code Style
+
+```solidity
+// SPDX-License-Identifier: MIT
+pragma solidity ^0.8.0;
+
+contract LN1Validator {
+    mapping(address => bool) public validators;
+    
+    event ValidationSubmitted(bytes32 indexed documentHash);
+    
+    function submitValidation(bytes32 documentHash) 
+        external 
+        onlyValidator 
+    {
+        // Implementation
+    }
+}
+```
+
+## Testing Requirements
+
+### Unit Tests
+
+- Minimum 80% code coverage
+- Test all edge cases
+- Include performance tests
+- Document test scenarios
+
+### Integration Tests
+
+```python
+@pytest.mark.integration
+async def test_document_flow():
+    # Setup
+    processor = DocumentProcessor()
+    document = create_test_document()
+
+    # Execute
+    result = await processor.process_document(document)
+
+    # Verify
+    assert result.status == "VALIDATED"
+    assert result.hash is not None
+```
+
+## Documentation
+
+### Code Documentation
+
+- Use descriptive variable names
+- Add comments for complex logic
+- Include type hints
+- Write comprehensive docstrings
+
+### API Documentation
+
+- Document all endpoints
+- Include request/response examples
+- Specify error responses
+- Maintain version information
+
+## Pull Request Process
+
+1. **Create Feature Branch**
+```bash
+git checkout -b feature/your-feature
+```
+
+2. **Development**
+- Write code following style guidelines
+- Add tests
+- Update documentation
+
+3. **Submit PR**
+- Fill out PR template
+- Link related issues
+- Add screenshots if applicable
+
+4. **Review Process**
+- Address reviewer comments
+- Update PR as needed
+- Ensure CI passes
+
+## Security Guidelines
+
+### Code Security
+
+- Follow OWASP guidelines
+- Implement input validation
+- Use secure dependencies
+- Regular security audits
+
+### Data Protection
+
+```python
+class SecurityManager:
+    def secure_data(self, data: Any) -> SecureData:
+        """
+        Implement security measures for data handling.
+        """
+        validated = self.validate_input(data)
+        encrypted = self.encrypt_sensitive_data(validated)
+        return self.apply_access_controls(encrypted)
+```
+
+## Performance Guidelines
+
+### Optimization
+
+- Use async/await for I/O operations
+- Implement proper caching
+- Optimize database queries
+- Profile code performance
+
+### Monitoring
+
+```python
+class PerformanceMonitor:
+    def track_metrics(self):
+        return {
+            'response_time': self.measure_response_time(),
+            'memory_usage': self.get_memory_usage(),
+            'cpu_usage': self.get_cpu_usage()
+        }
+```
+
+## Community Guidelines
+
+### Communication Channels
+
+- GitHub Issues for bug reports
+- Discussions for feature requests
+- Weekly dev meetings
+
+### Code of Conduct
+
+- Be respectful and inclusive
+- Follow project guidelines
+- Help others learn
