 Writing an Extension for Flake8
 ===============================
 
-Since Flake8 is now adding support for extensions, we require ``setuptools``

-existing tool compatible with Flake8 but do not already require 
-``setuptools``, you should probably add it to your list of requirements. Next,

-We used ``P10`` here, but in reality, you should check to prevent as much 
-future overlap as possible with other extensions. ``W`` and ``E`` followed by 
-three digits should be considered entirely reserved for pep8. ``F`` should be 
-considered reserved for Pyflakes and ``C`` for McCabe. Also, in anticipation 
-of possible pylint integration, ``W`` and ``E`` followed by four digits should 
-be considered reserved. We have no way of checking for those though, so while 
-we ask you not use them, we can not (currently) prevent you from doing so.
 
-A Real Example: McCabe
+If you intend to publish your extension, choose a unique code prefix
+following the convention for :ref:`error codes <error-codes>`.
+In addition, you can open a request in the `issue tracker
+<https://bitbucket.org/tarek/flake8/issues>`_ to register the prefix in the
+documentation.
