+
+Our Pledge
+----------
+
+In the interest of fostering an open and welcoming environment, we as contributors and maintainers pledge to make participation in our project and our community a harassment-free experience for everyone, regardless of age, body size, disability, ethnicity, gender identity and expression, level of experience, nationality, personal appearance, race, religion, or sexual identity and orientation.
+
+Our Standards
+-------------
+
+Examples of behavior that contributes to creating a positive environment include:
+
+* Using welcoming and inclusive language

+How To Contribute
+=================
+
+First off, thank you for considering contributing to ``attrs``!
+It's people like *you* who make it is such a great tool for everyone.
+
+This document is mainly to help you to get started by codifying tribal knowledge and expectations and make it more accessible to everyone.
+But don't be afraid to open half-finished PRs and ask questions if something is unclear!
+
+
+Support
+-------
+
+In case you'd like to help out but don't want to deal with GitHub, there's a great opportunity:
+help your fellow developers on `StackOverflow <https://stackoverflow.com/questions/tagged/python-attrs>`_!
+
+The offical tag is ``python-attrs`` and helping out in support frees us up for improving ``attrs`` instead!
+
+
+Workflow
+--------
+
+- No contribution is too small!
+  Please submit as many fixes for typos and grammar bloopers as you can!
+- Try to limit each pull request to *one* change only.
+- *Always* add tests and docs for your code.
+  This is a hard rule; patches with missing tests or documentation can't be merged.
+- Make sure your changes pass our CI_.
+  You won't get any feedback until it's green unless you ask for it.
+- Once you've addressed review feedback, make sure to bump the pull request with a short note, so we know you're done.
+- Don’t break `backward compatibility`_.
+
+
+Code
+----
+
+- Obey `PEP 8`_ and `PEP 257`_.
+  We use the ``"""``\ -on-separate-lines style for docstrings:
+
+  .. code-block:: python
+
+     def func(x):
+         """
+         Do something.
+
+         :param str x: A very important parameter.
+
+         :rtype: str
+         """
+- If you add or change public APIs, tag the docstring using ``..  versionadded:: 16.0.0 WHAT`` or ``..  versionchanged:: 16.2.0 WHAT``.
+- Prefer double quotes (``"``) over single quotes (``'``) unless the string contains double quotes itself.
+
+
+Tests
+-----
+
+- Write your asserts as ``expected == actual`` to line them up nicely:
+
+  .. code-block:: python
+
+     x = f()
+
+     assert 42 == x.some_attribute
+     assert "foo" == x._a_private_attribute
+
+- To run the test suite, all you need is a recent tox_.
+  It will ensure the test suite runs with all dependencies against all Python versions just as it will on Travis CI.
+  If you lack some Python versions, you can can always limit the environments like ``tox -e py27,py35`` (in that case you may want to look into pyenv_, which makes it very easy to install many different Python versions in parallel).
+- Write `good test docstrings`_.
+- To ensure new features work well with the rest of the system, they should be also added to our `Hypothesis`_ testing strategy which you find in ``tests/util.py``.
+
+
+Documentation
+-------------
+
+- Use `semantic newlines`_ in reStructuredText_ files (files ending in ``.rst``):
+
+  .. code-block:: rst
+
+     This is a sentence.
+     This is another sentence.
+
+- If you start a new section, add two blank lines before and one blank line after the header except if two headers follow immediately after each other:
+
+  .. code-block:: rst
+
+     Last line of previous section.
+
+
+     Header of New Top Section
+     -------------------------
+
+     Header of New Section
+     ^^^^^^^^^^^^^^^^^^^^^
+
+     First line of new section.
+- If you add a new feature, demonstrate its awesomeness in the `examples page`_!
+
+
+Changelog
+^^^^^^^^^
+
+If your change is noteworthy, there needs to be a changelog entry, so our users can learn about it!
+
+To avoid merge conflicts, we use the towncrier_ package to manage our changelog.
+``towncrier`` uses independent files for each pull request -- so called *news fragments* -- instead of one monolithic changelog file.
+On release those news fragments are compiled into our ``CHANGELOG.rst``.
+
+You don't need to install ``towncrier`` yourself, you just have to abide to a few simple rules:
+
+- For each pull request, add a new file into ``changelog.d`` with a filename adhering to the ``pr#.(change|deprecation|breaking).rst`` schema:
+  For example ``changelog.d/42.change.rst`` for a non-breaking change, that is proposed in pull request number 42.
+- As with other docs, please use `semantic newlines`_ within news fragments.
+- Wrap symbols like modules, functions, or classes into double backticks so they are rendered in a monospaced font.
+- If you mention functions or other callables, add parantheses at the end of their names: ``attr.func()`` or ``attr.Class.method()``.
+  This makes the changelog a lot more readable.
+- Prefer simple past or constructions with "now".
+  For example:
+
+  + Added ``attr.validators.func()``.
+  + ``attr.func()`` now doesn't crash the Large Hadron Collider anymore.
+- If you want to reference multiple issues, copy the news fragment to another filename.
+  ``towncrier`` will merge all news fragments with identical contents into one entry with multiple links to the respective pull requests.
+
+Example entries:
+
+  .. code-block:: rst
+
+     Added ``attr.validators.func()``.
+     The feature really *is* awesome.
+
+or:
+
+  .. code-block:: rst
+
+     ``attr.func()`` now doesn't crash the Large Hadron Collider anymore.
+     The bug really *was* nasty.
+
+----
+
+``tox -e changelog`` will render the current changelog to the terminal if you have any doubts.
+
+
+Local Development Environment
+-----------------------------
+
+You can (and should) run our test suite using tox_.
+However you’ll probably want a more traditional environment too.
+We highly recommend to develop using the latest Python 3 release because ``attrs`` tries to take advantage of modern features whenever possible.
+
+First create a `virtual environment <https://virtualenv.pypa.io/>`_.
+It’s out of scope for this document to list all the ways to manage virtual environments in Python but if you don’t have already a pet way, take some time to look at tools like `pew <https://github.com/berdario/pew>`_, `virtualfish <http://virtualfish.readthedocs.io/>`_, and `virtualenvwrapper <http://virtualenvwrapper.readthedocs.io/>`_.
+
+Next get an up to date checkout of the ``attrs`` repository:
+
+.. code-block:: bash
+
+    git checkout git@github.com:python-attrs/attrs.git
+
+Change into the newly created directory and **after activating your virtual environment** install an editable version of ``attrs``:
+
+.. code-block:: bash
+
+    cd attrs
+    pip install -e .
+
+If you run the virtual environment’s Python and try to ``import attr`` it should work!
+
+To run the test suite, you'll need our development dependencies which can be installed using
+
+.. code-block:: bash
+
+    pip install -r dev-requirements.txt
+
+At this point
+
+.. code-block:: bash
+
+   python -m pytest
+
+should work and pass!
+
+
+Governance
+----------
+
+``attrs`` is maintained by `team of volunteers`_ that is always open for new members that share our vision of a fast, lean, and magic-free library that empowers programmers to write better code with less effort.
+If you'd like to join, just get a pull request merged and ask to be added in the very same pull request!
+
+**The simple rule is that everyone is welcome to review/merge pull requests of others but nobody is allowed to merge their own code.**
+
+`Hynek Schlawack`_ acts reluctantly as the BDFL_ and has the final say over design decisions.
+
+
+****
+
+Please note that this project is released with a Contributor `Code of Conduct`_.
+By participating in this project you agree to abide by its terms.
+Please report any harm to `Hynek Schlawack`_ in any way you find appropriate.
+
+Thank you for considering contributing to ``attrs``!
