+Contributing to MongoEngine
+===========================
+
+MongoEngine has a large `community
+<https://raw.github.com/MongoEngine/mongoengine/master/AUTHORS>`_ and
+contributions are always encouraged. Contributions can be as simple as
+minor tweaks to the documentation. Please read these guidelines before
+sending a pull request.
+
+Bugfixes and New Features
+-------------------------
+
+Before starting to write code, look for existing `tickets
+<https://github.com/MongoEngine/mongoengine/issues?state=open>`_ or `create one
+<https://github.com/MongoEngine/mongoengine/issues>`_ for your specific
+issue or feature request. That way you avoid working on something
+that might not be of interest or that has already been addressed.  If in doubt
+post to the `user group <http://groups.google.com/group/mongoengine-users>`
+
+Supported Interpreters
+----------------------
+
+PyMongo supports CPython 2.5 and newer. Language
+features not supported by all interpreters can not be used.
+Please also ensure that your code is properly converted by
+`2to3 <http://docs.python.org/library/2to3.html>`_ for Python 3 support.
+
+Style Guide
+-----------
+
+MongoEngine aims to follow `PEP8 <http://www.python.org/dev/peps/pep-0008/>`_
+including 4 space indents and 79 character line limits.
+
+Testing
+-------
+
+All tests are run on `Travis <http://travis-ci.org/MongoEngine/mongoengine>`_
+and any pull requests are automatically tested by Travis. Any pull requests
+without tests will take longer to be integrated and might be refused.
+
+General Guidelines
+------------------
+
+- Avoid backward breaking changes if at all possible.
+- Write inline documentation for new classes and methods.
+- Write tests and make sure they pass (make sure you have a mongod
+  running on the default port, then execute ``python setup.py test``
+  from the cmd line to run the test suite).
+- Add yourself to AUTHORS.rst :)
+
+Documentation
+-------------
+
+To contribute to the `API documentation
+<http://docs.mongoengine.org/en/latest/apireference.html>`_
+just make your changes to the inline documentation of the appropriate
+`source code <https://github.com/mongoengine/MongoEngine>`_ or `rst file
+<https://github.com/mongoengine/MongoEngine/tree/master/docs>`_ in a
+branch and submit a `pull request <https://help.github.com/articles/using-pull-requests>`_.
+You might also use the github `Edit <https://github.com/blog/844-forking-with-the-edit-button>`_
+button.
