   * While not all components of Ansible must be in Python, core contributions to the Ansible repo must be written in Python.  This is to maximize the ability of everyone to contribute.

 ===========================
 
-  * [PEP 8](https://www.python.org/dev/peps/pep-0008/) is a great Python style guide, which you should read.
-  * PEP 8 must not be strictly followed in all aspects, but most of it is good advice

+  * PEP8 must not be strictly followed in all aspects, but most of it is good advice
   * In particular, we don't really care about line lengths.  Buy a bigger monitor!
-  * To run checks for things we care about, use [ansible-test](http://docs.ansible.com/ansible/dev_guide/testing_pep8.html#running-locally).
+  * To run checks for things we care about, run "make pep8"
   * Similarly, additional checks can be made with "make pyflakes"
-  * There is no need to submit code changes for PEP 8 and pyflakes fixes, as these break attribution history.  Project leadership will make these periodically.
