 Reporting issues
 ----------------
 
-- Describe what you expected to happen.
-- If possible, include a `minimal reproducible example`_ to help us
-  identify the issue. This also helps check that the issue is not with
-  your own code.
-- Describe what actually happened. Include the full traceback if there was an
-  exception.
-- List your Python, Flask, and Werkzeug versions. If possible, check if this
-  issue is already fixed in the repository.

 Submitting patches
 ------------------
 
-- Use `Black`_ to autoformat your code. This should be done for you as a
-  git `pre-commit`_ hook, which gets installed when you run ``pip install -e .[dev]``.
-  You may also wish to use Black's `Editor integration`_.
-- Include tests if your patch is supposed to solve a bug, and explain
-  clearly under which circumstances the bug happens. Make sure the test fails
-  without your patch.
-- Include a string like "Fixes #123" in your commit message
-  (where 123 is the issue you fixed).
-  See `Closing issues using keywords
-  <https://help.github.com/articles/creating-a-pull-request/>`__.
