+
+Implement Features
+~~~~~~~~~~~~~~~~~~
+
+Look through the GitHub issues for features. Anything tagged with "feature"
+is open to whoever wants to implement it.
+
+Write Documentation
+~~~~~~~~~~~~~~~~~~~
+
+Django HTTP Referrer Policy could always use more documentation, whether as part of the 
+official Django HTTP Referrer Policy docs, in docstrings, or even on the web in blog posts,
+articles, and such.
+
+Submit Feedback
+~~~~~~~~~~~~~~~
+
+The best way to send feedback is to file an issue at https://github.com/DmytroLitvinov/django-http-referrer-policy/issues.
+
+If you are proposing a feature:
+
+* Explain in detail how it would work.
+* Keep the scope as narrow as possible, to make it easier to implement.
+* Remember that this is a volunteer-driven project, and that contributions
+  are welcome :)
+
+Get Started!
+------------
+
+Ready to contribute? Here's how to set up `django-http-referrer-policy` for local development.
+
+1. Fork the `django-http-referrer-policy` repo on GitHub.
+2. Clone your fork locally::
+
+    $ git clone git@github.com:your_name_here/django-http-referrer-policy.git
+
+3. Install your local copy into a virtualenv. Assuming you have virtualenvwrapper installed, this is how you set up your fork for local development::
+
+    $ mkvirtualenv django-http-referrer-policy
+    $ cd django-http-referrer-policy/
+    $ python setup.py develop
+
+4. Create a branch for local development::
+
+    $ git checkout -b name-of-your-bugfix-or-feature
+
+   Now you can make your changes locally.
+
+5. When you're done making changes, check that your changes pass flake8 and the
+   tests, including testing other Python versions with tox::
+
+        $ flake8 django_http_referrer_policy tests
+        $ python setup.py test
+        $ tox
+
+   To get flake8 and tox, just pip install them into your virtualenv. 
+
+6. Commit your changes and push your branch to GitHub::
+
+    $ git add .
+    $ git commit -m "Your detailed description of your changes."
+    $ git push origin name-of-your-bugfix-or-feature
+
+7. Submit a pull request through the GitHub website.
+
+Pull Request Guidelines
+-----------------------
+
+Before you submit a pull request, check that it meets these guidelines:
+
+1. The pull request should include tests.
+2. If the pull request adds functionality, the docs should be updated. Put
+   your new functionality into a function with a docstring, and add the
+   feature to the list in README.rst.
+3. The pull request should work for Python 2.6, 2.7, and 3.3, and for PyPy. Check 
+   https://travis-ci.org/DmytroLitvinov/django-http-referrer-policy/pull_requests
+   and make sure that the tests pass for all supported Python versions.
+
+Tips
+----
+
+To run a subset of tests::
+
+    $ python -m unittest tests.test_django_http_referrer_policy
