+## 🦠 Supported Virus Types
+
+Maya Umbrella currently detects and removes the following virus families:
+
+| Virus Family | Description | Detection Method |
+|--------------|-------------|------------------|
+| **PutTianTongQi** | Early Maya virus that creates `fuckVirus.py` files | File signature detection |
+| **ZeiJianKang** | Creates malicious `vaccine.py` and modifies userSetup files | Script node analysis |
+| **Virus2024429** | Advanced virus using `_gene` nodes and `uifiguration` | Pattern matching + signature detection |
+| **Leukocyte** | Latest sophisticated virus family with multiple variants | Multi-layer detection including base64 decoding |
+
+### 🔬 Leukocyte Virus Detection
+
+The Leukocyte virus family is particularly sophisticated and includes:
+- **Script injection** via `phage` class implementations
+- **Persistent execution** through Maya scriptJobs
+- **Base64 encoded payloads** for obfuscation
+- **File system manipulation** targeting userSetup files
+- **Scene contamination** through script nodes
+
+Maya Umbrella uses advanced detection techniques including:
+- Pattern recognition for virus signatures
+- Base64 payload analysis
+- Script job monitoring
+- File integrity checking

+## Testing
+
+### Unit Tests
+Run the complete test suite with coverage:
+```shell

+```
+
+### Cross-Platform Python 2.7 Testing
+
+Maya Umbrella supports both Python 2.7 (Maya 2018-2020) and Python 3.x (Maya 2022+). We provide comprehensive testing for both environments:
+
+#### GitHub Actions CI Testing
+- **Linux Maya Testing**: Automated tests using `mottosso/maya:2018/2019/2020` Docker images
+- **Windows Python 2.7**: Compatibility testing on Windows with Python 2.7
+- **Multi-platform validation**: Tests run on Ubuntu, Windows, and macOS
+
+#### Local Python 2.7 Testing (Windows)
+For local Python 2.7 compatibility testing on Windows:
+
+```batch
+# Run the test script directly
+python scripts/test_python27_windows.py
+
+# Or use the convenient batch file
+scripts/test_python27_windows.bat
+```
+
+This local test script verifies:
+- ✅ Core module imports and functionality
+- ✅ Python 2.7 syntax compatibility
+- ✅ File system operations
+- ✅ Vaccine class instantiation
+- ✅ Unicode handling (Python 2.7 specific)
+
+#### Maya Version Compatibility Matrix
+
+| Maya Version | Python Version | Testing Method | Status |
+|--------------|----------------|----------------|---------|
+| 2018-2020 | Python 2.7 | Docker + Local | ✅ Fully Tested |
+| 2022+ | Python 3.7+ | Standard CI | ✅ Fully Tested |
+
+#### Integration Tests
+Run integration tests that require Maya:
+```shell
+nox -s maya-integration
+```
+
+## 🔒 Security & Safety
+
+Maya Umbrella is designed with security as a top priority:
+
+### Safe Testing
+- **No real virus files** are included in the repository
+- **Mock virus files** are generated dynamically for testing
+- **Docker isolation** for integration testing in CI environments
+- **Signature-based detection** without executing malicious code
+
+### Safe Operation
+- **Automatic backup** of files before cleaning (configurable)
+- **Non-destructive scanning** - analysis only, no automatic changes
+- **Detailed logging** of all operations
+- **Rollback capability** through backup files
+
+### Development Security
+- **Comprehensive test coverage** (72%+) with both unit and integration tests
+- **Static code analysis** with ruff and isort
+- **CI/CD validation** on multiple platforms and Python versions
+- **Code review process** for all changes
