+Some Helpful Tools for Python Code Quality
+------------------------------------------
+
+There are various tools that can help you to check your Python code for PEP8
+conformance and general code quality. We recommend using them.
+
+* `pep8`_ checks your Python code against some of the style conventions in PEP
+  8. As mentioned above, only perform style clean-ups on master to help avoid
+  spurious merge conflicts.
 
-`PyLint`_ is a useful tool for analysing python source code for errors and signs of poor quality.
+* `pylint`_ analyzes Python source code looking for bugs and signs of poor
+  quality.
 
-`pyflakes`_ is another useful tool for passive analysis of python source code.
-There's also a `pyflakes vim plugin`_ which will highlight unused variables,
-undeclared variables, syntax errors and unused imports.
+* `pyflakes`_ also analyzes Python programs to detect errors.

+* `flake8`_ combines both pep8 and pyflakes into a single tool.
+
+* `Syntastic`_ is a Vim plugin with support for flake8, pyflakes and pylint.
