+# Python 3.9-3.13 Compatibility Changes
+
+This document summarizes the changes made to make pyace compatible with Python 3.9 through 3.13.
+
+## Key Changes
+
+### 1. Modern Package Configuration
+- **Added `pyproject.toml`**: Modern Python packaging standard (PEP 518/517)
+- **Updated `setup.py`**: Simplified and modernized, handles CMake extensions
+- **Updated `setup.cfg`**: Minimal configuration, most moved to pyproject.toml
+
+### 2. Dependency Management
+- **Updated version constraints**: Removed upper bounds that were too restrictive
+- **Added conditional dependencies**: `packaging>=20.0` for Python 3.12+ (distutils removal)
+- **Modernized requirements**: Specified minimum versions for better compatibility
+
+### 3. Python Version Support
+- **Supported versions**: Python 3.9, 3.10, 3.11, 3.12, 3.13
+- **Build system**: Uses setuptools with CMake for C++ extensions
+- **CI/CD**: Updated GitHub Actions to test all supported versions
+
+### 4. Compatibility Fixes
+- **distutils handling**: Added fallback to `packaging.version` for Python 3.12+
+- **String formatting**: Code review showed no compatibility issues
+- **Import statements**: All imports are compatible across versions
+
+### 5. Development Tools
+- **Added `requirements-dev.txt`**: Development dependencies
+- **Added `test_compatibility.py`**: Simple test script to verify installation
+- **Updated CI/CD**: Comprehensive testing across Python versions and OS
+
+## Files Modified
+
+### Core Configuration
+- `pyproject.toml` - **NEW**: Modern package configuration
+- `setup.py` - **UPDATED**: Simplified, Python 3.12+ compatible
+- `setup.cfg` - **UPDATED**: Minimal configuration
+- `requirements.txt` - **UPDATED**: Version constraints
+- `MANIFEST.in` - **UPDATED**: Include new files
+
+### Development
+- `requirements-dev.txt` - **NEW**: Development dependencies
+- `test_compatibility.py` - **NEW**: Compatibility test script
+- `.github/workflows/test.yml` - **UPDATED**: Test Python 3.9-3.13
+
+## Installation
+
+### For Users
+```bash
+# Install from source
+pip install .
+
+# Or editable install for development
+pip install -e .
+```
+
+### For Developers
+```bash
+# Install development dependencies
+pip install -r requirements-dev.txt
+
+# Install package in editable mode
+pip install -e .
+
+# Run tests
+pytest tests/
+```
+
+### Testing Compatibility
+```bash
+# Run compatibility test
+python test_compatibility.py
+
+# Test with specific Python version
+python3.11 test_compatibility.py
+```
+
+## Key Dependencies
+
+- **numpy**: ≥1.19.0 (Python 3.9+ compatible)
+- **ase**: ≥3.22.0 (Atomic Simulation Environment)
+- **pandas**: ≥1.3.0 (Data manipulation)
+- **scikit-learn**: ≥1.0.0 (Machine learning)
+- **packaging**: ≥20.0 (Python 3.12+ only, replaces distutils)
+
+## Build Requirements
+
+- **CMake**: ≥3.12
+- **C++ compiler**: C++14 compatible
+- **pybind11**: ≥2.6.0
+- **ninja**: Recommended for faster builds
+
+## Testing
+
+The package is tested on:
+- **Python versions**: 3.9, 3.10, 3.11, 3.12, 3.13
+- **Operating systems**: Ubuntu, macOS
+- **Architectures**: x86_64, ARM64 (Apple Silicon)
+
+## Backward Compatibility
+
+All changes maintain backward compatibility with existing:
+- API interfaces
+- Configuration files
+- Data formats
+- Usage patterns
+
+## Future Maintenance
+
+- Monitor Python release schedule for new versions
+- Update CI/CD when Python 3.14 is released
+- Review dependencies for compatibility issues
+- Consider migration to newer build systems (e.g., scikit-build-core) when appropriate
