-==============
-
-.. This file based on https://github.com/PyGithub/PyGithub/blob/master/CONTRIBUTING.md
-
-``flake8-encodings`` uses `tox <https://tox.readthedocs.io>`_ to automate testing and packaging,
-and `pre-commit <https://pre-commit.com>`_ to maintain code quality.
-
-Install ``pre-commit`` with ``pip`` and install the git hook:
-
-.. prompt:: bash
-
-	python -m pip install pre-commit
-	pre-commit install
-
-
-Coding style
---------------
-
-`formate <https://formate.readthedocs.io>`_ is used for code formatting.
-
-It can be run manually via ``pre-commit``:
-
-.. prompt:: bash
-
-	pre-commit run formate -a
-
-
-Or, to run the complete autoformatting suite:
-
-.. prompt:: bash
-
-	pre-commit run -a
-
-
-Automated tests
--------------------
-
-Tests are run with ``tox`` and ``pytest``.
-To run tests for a specific Python version, such as Python 3.6:
-
-.. prompt:: bash
-
-	tox -e py36
-
-
-To run tests for all Python versions, simply run:
-
-.. prompt:: bash
-
-	tox
-
-
-Type Annotations
--------------------
-
-Type annotations are checked using ``mypy``. Run ``mypy`` using ``tox``:
-
-.. prompt:: bash
-
-	tox -e mypy
-
-
-
-Build documentation locally
-------------------------------
-
-The documentation is powered by Sphinx. A local copy of the documentation can be built with ``tox``:
-
-.. prompt:: bash
-
-	tox -e docs
