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

Ready to contribute? Here's how to set up `ordr2` for local development.

1. Fork the `ordr2` repo on GitHub.
2. Clone your fork locally::

    $ git clone https://git.cpi.imtek.uni-freiburg.de/your_name_here/ordr2/

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 ordr2
    $ cd ordr2/
    $ 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 ordr2 tests
    $ python setup.py test or 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.


Tips

To run a subset of tests::

$ py.test tests.test_ordr2
