+
+## Requirements
+
+Python 3.12. May work with other versions, but not guaranteed.
+
+## Development
+
+It's recommended to do development with [Venv](https://docs.python.org/3/library/venv.html). To set up the environment run:
+
+```
+python -m venv .venv
+source .venv/bin/activate
+pip install -r requirements.txt
+```
+
+## Testing
+
+To install test modules run:
+
+```
+pip install -r requirements-test.txt
+```
+
+Testing is done by [Tox](https://tox.wiki). Run `tox` for all tests. Settings can be changed in tox.ini.
+
+Unit tests are run with [Pytest](https://docs.pytest.org). Test files live in tests/.
+
+Style is checked by [Flake8](https://flake8.pycqa.org/).
+
+Module import order is handled by [Isort](https://pycqa.github.io/isort/).
+
+### CI
+
+Github actions are specified in .github/workflows/python.yml. By deafult Tox will run when code is pushed.
