+Contributing
+============
+
+Contributions are welcome, and they are greatly appreciated! Every little bit
+helps, and credit will always be given.
+
+You can contribute in many ways:
+
+Types of Contributions
+----------------------
+
+Report Bugs
+~~~~~~~~~~~
+
+Report bugs at https://gitlab.mpcdf.mpg.de/dboe/tfields/issues.
+
+If you are reporting a bug, 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.
+
+Fix Bugs
+~~~~~~~~
+
+Look through the repository issues for bugs. Anything tagged with "bug" and "help
+wanted" is open to whoever wants to implement it.
+
+Implement Features
+~~~~~~~~~~~~~~~~~~
+
+Look through the remote issues for features. Anything tagged with "enhancement"
+and "help wanted" is open to whoever wants to implement it.
+
+Write Documentation
+~~~~~~~~~~~~~~~~~~~
+
+tfields could always use more documentation, whether as part of the
+official tfields 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://gitlab.mpcdf.mpg.de/dboe/tfields/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 `tfields` for local development.
+
+1. Fork the `tfields` repo.
+2. Clone your fork locally::
+
+    $ git clone git@gitlab.mpcdf.mpg.de:your_name_here/tfields.git
+
+3. Set up your fork for local development::
+
+    $ cd tfields/
+    $ 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::
+
+    $ make test
+
+6. Commit your changes and push your branch to origin::
+
+    $ 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 repository 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 3.5, 3.6, 3.7 and 3.8, and for PyPy. Check
+   https://travis-ci.com/dboe/tfields/pull_requests
+   and make sure that the tests pass for all supported Python versions.
+
+Tips
+----
+
+To run a subset of tests, you have the following options::
+
+    $ pytest tests/test_package.py
+
+    $ pytest tests/test_package.py::Test_tfields::test_version_type
+
+    $ pytest --doctest-modules docs/usage.rst
+
+    $ pytest --doctest-modules tfields/core.py -k "MyClass.funciton_with_doctest"
+
+Use the '--trace' option to directly jump into a pdb debugger on fails
+
+
+Deploying
+---------
+
+A reminder for the maintainers on how to deploy.
+Make sure all your changes are committed (including an entry in HISTORY.rst if you have one).
+Then run::
+
+$ bump2version patch # possible: major / minor / patch
+$ git push
+$ git push --tags
+
+or without bump2version just do
+
+$ make publish
+
+Travis will then deploy to PyPI if tests pass.
