+### Running flake8 for Python code
+
+[Flake8](http://flake8.pycqa.org/en/latest/) is a tool for checking correctness and style of Python code.
+
+The setup for Flake8 is defined in `setup.cfg`.
+
+Flake8 should be run from the top level directory, ideally code should be reviewed to make sure there are no
+flake errors before it is merged.
