+
+- **Clear title**: A brief, descriptive title
+- **Environment details**: Python version, OS, SQL Server version
+- **Steps to reproduce**: Detailed steps that led to the issue
+- **Expected behavior**: What you expected to happen
+- **Actual behavior**: What actually happened
+- **Error messages**: Full error messages or stack traces
+- **Additional context**: Screenshots, configuration files (without sensitive data)
+
+### Suggesting Enhancements
+
+Enhancement suggestions are welcome! Please include:
+
+- **Clear title**: Brief description of the enhancement
+- **Detailed description**: Explain the enhancement and its benefits
+- **Use cases**: Real-world scenarios where this would be helpful
+- **Implementation ideas**: If you have thoughts on how to implement it
+
+### Pull Requests
+
+1. **Fork the repository** and create your branch from `main`
+2. **Make your changes** following the coding standards below
+3. **Test your changes** thoroughly
+4. **Update documentation** if necessary
+5. **Commit your changes** with clear, descriptive messages
+6. **Submit a pull request** with a clear description
+
+## Development Setup
+
+1. Fork and clone the repository:
+   ```bash
+   git clone https://github.com/Aditya-Raj-Parashar/data-entry.git
+   cd database-updater
+   ```
+
+2. Create a virtual environment:
+   ```bash
+   python -m venv venv
+   source venv/bin/activate  # On Windows: venv\Scripts\activate
+   ```
+
+3. Install dependencies:
+   ```bash
+   pip install -r requirements.txt
+   ```
+
+## Coding Standards
+
+### Python Style Guide
+
+- Follow [PEP 8](https://www.python.org/dev/peps/pep-0008/) style guidelines
+- Use meaningful variable and function names
+- Add docstrings to functions and classes
+- Keep functions focused and small
+- Use type hints where appropriate
+
+### Code Organization
+
+- Keep the main logic in `database_updater.py`
+- Add utility functions to separate modules if needed
+- Include error handling for all database operations
+- Use logging instead of print statements for debugging
+
+### Documentation
+
+- Update README.md for new features
+- Add docstrings to new functions
+- Include inline comments for complex logic
+- Update requirements.txt if adding new dependencies
+
+## Testing
+
+Currently, the project uses basic import testing. When contributing:
+
+- Test your code with different CSV file formats
+- Test with different SQL Server configurations
+- Verify error handling works correctly
+- Test both Windows and SQL Server authentication methods
+
+## Git Workflow
+
+### Branching Strategy
+
+- `main`: Production-ready code
+- `develop`: Integration branch for features
+- `feature/feature-name`: New features
+- `bugfix/bug-name`: Bug fixes
+- `hotfix/issue-name`: Critical fixes
+
+### Commit Messages
+
+Use clear, descriptive commit messages:
+
+```
+Add support for custom data types in CSV import
+
+- Allow users to specify column data types
+- Add validation for supported SQL Server types
+- Update documentation with examples
+```
+
+### Pull Request Process

+2. Update documentation as needed
+3. Test your changes thoroughly
+4. Write a clear PR description explaining:
+   - What changes were made
+   - Why they were made
+   - How to test them
+   - Any breaking changes
+
+## Questions?
