+We support all current supported versions of Python. When introducing new dependencies or syntax, please ensure they are available and function correctly across all supported Python versions.
 If code requires version-specific logic, use clear and well-documented conditional statements. Please verify changes using the test suite in each supported Python environment.
 
 
 ## Testing
 
 - All new features and bugfixes must include tests.
-- We use [pytest](https://docs.pytest.org/) for testing. Add your tests in the `tests/` directory.
+- We use the python `unittest` module for testing to avoid additional dependencies. Add your tests in the `tests/` directory.
 - Ensure your code passes all tests before submitting a PR:
   ```
-  pytest
+  python3 -m unittest
   ```
 - We expect **100% test coverage** for new code (exceptions may be discussed in PRs).
