+## Pull Request Process
+
+Pull requests are the best way to propose changes to the codebase (we use Github
+Flow). We actively welcome your pull requests:
+
+1. Fork the repo and create your branch from master.
+2. If you've added code that should be tested, add tests.
+3. If you add a new sub-package, update the documentation.
+4. Make sure your code lints (see below).
+5. Ensure the test suite passes (see below).
+6. Ensure the documentation builds (see below).
+7. Issue the pull request!
+
+## Code style and basic checks
+
+* `pyflakes` should run without any error.
+* The code needs to be PEP8 compliant (the line length should not exceed  120
+* characters). This can be checked using `pycodestyle`.
+* `pydocstyle` should run without error.
+
+Here is a typical way to run all these tests (from the repository root)::
+
+    $ pyflakes src tests
+    $ pycodestyle --max-line-length=120 --ignore=W504 src
+    $ pycodestyle --max-line-length=120 --ignore=W504 tests
+    $ pydocstyle
+
+If no warning pops up, that(s) ok!
+
+## Test suite
+
+Launching the `pytest` command at the repository root will run all the unit
+tests. 
+
+## Documentation builds
+
+The `docs` subdirectory is equipped with a Makefile::
+
+    $ cd docs
+    $ make
+    ...
