-How to contribute to Jinja
-==========================
-
-Thank you for considering contributing to Jinja!
-
-
-Support questions
------------------
-
-Please, don't use the issue tracker for this. The issue tracker is a
-tool to address bugs and feature requests in Jinja itself. Use one of
-the following resources for questions about using Jinja or issues with
-your own code:
-
--   The ``#get-help`` channel on our Discord chat:
-    https://discord.gg/t6rrQZH
--   The mailing list flask@python.org for long term discussion or larger
-    issues.
--   Ask on `Stack Overflow`_. Search with Google first using:
-    ``site:stackoverflow.com jinja {search term, exception message, etc.}``
-
-.. _Stack Overflow: https://stackoverflow.com/questions/tagged/jinja?sort=linked
-
-
-Reporting issues
-----------------
-
-Include the following information in your post:
-
--   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 and Jinja versions. If possible, check if this
-    issue is already fixed in the latest releases or the latest code in
-    the repository.
-
-.. _minimal reproducible example: https://stackoverflow.com/help/minimal-reproducible-example
-
-
-Submitting patches
-------------------
-
-If there is not an open issue for what you want to submit, prefer
-opening one for discussion before working on a PR. You can work on any
-issue that doesn't have an open PR linked to it or a maintainer assigned
-to it. These show up in the sidebar. No need to ask if you can work on
-an issue that interests you.
-
-Include the following in your patch:
-
--   Use `Black`_ to format your code. This and other tools will run
-    automatically if you install `pre-commit`_ using the instructions
-    below.
--   Include tests if your patch adds or changes code. Make sure the test
-    fails without your patch.
--   Update any relevant docs pages and docstrings. Docs pages and
-    docstrings should be wrapped at 72 characters.
--   Add an entry in ``CHANGES.rst``. Use the same style as other
-    entries. Also include ``.. versionchanged::`` inline changelogs in
-    relevant docstrings.

-First time setup
-~~~~~~~~~~~~~~~~
-
--   Download and install the `latest version of git`_.
--   Configure git with your `username`_ and `email`_.
-
-    .. code-block:: text
-
-        $ git config --global user.name 'your name'
-        $ git config --global user.email 'your email'
-
--   Make sure you have a `GitHub account`_.

-
-    .. code-block:: text
-
-        $ git clone https://github.com/pallets/jinja
-        $ cd jinja
-
--   Add your fork as a remote to push your work to. Replace
-    ``{username}`` with your username. This names the remote "fork", the
-    default Pallets remote is "origin".
-
-    .. code-block:: text
-
-        git remote add fork https://github.com/{username}/jinja
-
--   Create a virtualenv.
-
-    .. code-block:: text
-
-        $ python3 -m venv env
-        $ . env/bin/activate
-
-    On Windows, activating is different.
-
-    .. code-block:: text
-
-        > env\Scripts\activate
-
--   Install Jinja in editable mode with development dependencies.
-
-    .. code-block:: text
-
-        $ pip install -e . -r requirements/dev.txt
-
--   Install the pre-commit hooks.
-
-    .. code-block:: text
-
-        $ pre-commit install

-
-Start coding
-~~~~~~~~~~~~
-
--   Create a branch to identify the issue you would like to work on. If
-    you're submitting a bug or documentation fix, branch off of the
-    latest ".x" branch.
-
-    .. code-block:: text
-
-        $ git fetch origin
-        $ git checkout -b your-branch-name origin/1.1.x
-
-    If you're submitting a feature addition or change, branch off of the
-    "master" branch.
-
-    .. code-block:: text
-
-        $ git fetch origin
-        $ git checkout -b your-branch-name origin/master
-
--   Using your favorite editor, make your changes,
-    `committing as you go`_.
--   Include tests that cover any code changes you make. Make sure the
-    test fails without your patch. Run the tests as described below.
--   Push your commits to your fork on GitHub and
-    `create a pull request`_. Link to the issue being addressed with
-    ``fixes #123`` in the pull request.
-
-    .. code-block:: text
-
-        $ git push --set-upstream fork your-branch-name

-.. _create a pull request: https://help.github.com/en/articles/creating-a-pull-request
-
-
-Running the tests
-~~~~~~~~~~~~~~~~~
-
-Run the basic test suite with pytest.
-
-.. code-block:: text
-
-    $ pytest
-
-This runs the tests for the current environment, which is usually
-sufficient. CI will run the full suite when you submit your pull
-request. You can run the full test suite with tox if you don't want to
-wait.
-
-.. code-block:: text
-
-    $ tox
-
-
-Running test coverage
-~~~~~~~~~~~~~~~~~~~~~
-
-Generating a report of lines that do not have test coverage can indicate
-where to start contributing. Run ``pytest`` using ``coverage`` and
-generate a report.
-
-.. code-block:: text
-
-    $ pip install coverage
-    $ coverage run -m pytest
-    $ coverage html
-
-Open ``htmlcov/index.html`` in your browser to explore the report.
-
-Read more about `coverage <https://coverage.readthedocs.io>`__.
-
-
-Building the docs
-~~~~~~~~~~~~~~~~~
-
-Build the docs in the ``docs`` directory using Sphinx.
-
-.. code-block:: text
-
-    $ cd docs
-    $ make html
-
-Open ``_build/html/index.html`` in your browser to view the docs.
-
-Read more about `Sphinx <https://www.sphinx-doc.org/en/stable/>`__.
