+============
+Contributing
+============
+
+Contributions are welcome, and they are greatly appreciated! Every
+little bit helps, and credit will always be given.
+
+Bug reports
+===========
+
+When `reporting a bug <https://github.com/PeteCoward/python-catalpa-tools/issues>`_ please include:
+
+    * Your operating system name and version.
+    * Any details about your local setup that might be helpful in troubleshooting.
+    * Detailed steps to reproduce the bug.
+
+Documentation improvements
+==========================
+
+Catalpa Tools could always use more documentation, whether as part of the
+official Catalpa Tools docs, in docstrings, or even on the web in blog posts,
+articles, and such.
+
+Feature requests and feedback
+=============================
+
+The best way to send feedback is to file an issue at https://github.com/PeteCoward/python-catalpa-tools/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 code contributions are welcome :)
+
+Development
+===========
+
+To set up `python-catalpa-tools` for local development:
+
+1. Fork `python-catalpa-tools <https://github.com/PeteCoward/python-catalpa-tools>`_
+   (look for the "Fork" button).
+2. Clone your fork locally::
+
+    git clone git@github.com:your_name_here/python-catalpa-tools.git
+
+3. Create a branch for local development::
+
+    git checkout -b name-of-your-bugfix-or-feature
+
+   Now you can make your changes locally.
+
+4. When you're done making changes, run all the checks, doc builder and spell checker with `tox <http://tox.readthedocs.io/en/latest/install.html>`_ one command::
+
+    tox
+
+5. 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
+
+6. Submit a pull request through the GitHub website.
+
+Pull Request Guidelines
+-----------------------
+
+If you need some code review or feedback while you're developing the code just make the pull request.
+
+For merging, you should:
+
+1. Include passing tests (run ``tox``) [1]_.
+2. Update documentation when there's new API, functionality etc.
+3. Add a note to ``CHANGELOG.rst`` about the changes.
+4. Add yourself to ``AUTHORS.rst``.
+
+.. [1] If you don't have all the necessary python versions available locally you can rely on Travis - it will
+       `run the tests <https://travis-ci.org/PeteCoward/python-catalpa-tools/pull_requests>`_ for each change you add in the pull request.
+
+       It will be slower though ...
+
+Tips
+----
+
+To run a subset of tests::
+
+    tox -e envname -- pytest -k test_myfeature
+
+To run all the test environments in *parallel* (you need to ``pip install detox``)::
+
+    detox

+Why does this file exist, and why not put this in __main__?
+
+  You might be tempted to import things from __main__ later, but that will cause
+  problems: the code will get executed twice:
+
+  - When you run `python -mcatalpa_tools` python will execute
+    ``__main__.py`` as a script. That means there won't be any
+    ``catalpa_tools.__main__`` in ``sys.modules``.
+  - When you import __main__ it will get executed again (as a module) because
+    there's no ``catalpa_tools.__main__`` in ``sys.modules``.
