for features. Anything tagged with "feature" is open to whoever wants to implement it.

Write Documentation

articles, and such.

Submit Feedback

The best way to send feedback is to file an issue at https://github.com/trungdong/prov/issues.

If you are proposing a feature:

* Explain in detail how it would work.

  are welcome :)

Get Started!
------------

Ready to contribute? Here's how to set up `prov` for local development.

1. Fork the `prov` repo on GitHub.
2. Clone your fork locally::

    $ git clone git@github.com:your_name_here/prov.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 prov
    $ cd prov/
    $ pip install -r requirements-dev.txt

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 prov tests
    $ python setup.py test
    $ tox

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 2.7, 3.3, 3.4, 3.5, 3.6, and for PyPy.
   Check https://travis-ci.org/trungdong/prov/pull_requests
   and make sure that the tests pass for all supported Python versions.
   (See `pyenv <https://github.com/yyuu/pyenv>`_ for help on setting up
   multiple versions of Python locally for testing.)

Tips
----

To run a subset of tests::

	$ python -m unittest prov.tests.test_json
