    This ensures code is automatically formatted and checked before commits.
 
-## Development Workflow
-
-### Code Style
-
-ITKIT follows these code style guidelines:
-
-- **Python version:** >= 3.10
-- **Formatter:** Black with 150 character line length
-- **Import sorting:** isort with black profile
-- **Type hints:** Encouraged for public APIs
-- **Docstrings:** Follow NumPy/Google style
-
-### Running Tests
-
-ITKIT uses pytest for testing:
-
-```bash
-# Run all tests
-pytest
-
-# Run specific test file
-pytest tests/test_io.py
-
-# Run tests with specific marker
-pytest -m torch  # Only PyTorch tests
-pytest -m itk_process  # Only ITK processing tests
-
-# Run with coverage
-pytest --cov=itkit
-```
-
-Available test markers:
-
-- `gui`: GUI tests (requires Qt)
-- `itk_process`: ITK preprocessing script tests
-- `mm`: MMEngine runner tests
-- `torch`: PyTorch-dependent tests
-
-### Code Formatting
-
-Format your code before committing:
-
-```bash
-# Format with black
-black itkit/
-
-# Sort imports
-isort itkit/
-
-# Or use pre-commit to run all checks
-pre-commit run --all-files
-```
-
-### Type Checking
-
-Run type checkers:
-
-```bash
-# Pyright
-pyright
-
-# Mypy
-mypy itkit/
-```
-
-## Contribution Guidelines
-
-### Reporting Issues
-

-### Submitting Pull Requests
-
-1. **Create a new branch** for your feature/fix:
-
-   ```bash
-   git checkout -b feature/my-new-feature
-   ```
-
-2. **Make your changes** following code style guidelines
-
-3. **Add tests** for new functionality
-
-4. **Update documentation** if needed
-
-5. **Run tests** to ensure nothing breaks:
-
-   ```bash
-   pytest
-   ```
-
-6. **Commit your changes** with clear messages:
-
-   ```bash
-   git commit -m "Add feature: description of feature"
-   ```
-
-7. **Push to your fork:**
-
-   ```bash
-   git push origin feature/my-new-feature
-   ```
-
-8. **Create a Pull Request** on GitHub

-## Troubleshooting
-
-### Import Errors
-
-If you encounter import errors, ensure all dependencies are installed:
-
-```bash
-pip install itkit --force-reinstall
-```
-
-### GUI DPI Issues
-
-If the GUI's DPI is not optimal, specify the `QT_SCALE_FACTOR` environment variable:
-
-```bash
-QT_SCALE_FACTOR=2 itkit-app
-```
-
-### PyTorch Compatibility
-
-For GPU support with PyTorch-based features, install PyTorch separately following the [official PyTorch installation guide](https://pytorch.org/get-started/locally/).
