 - You now want to update your forked CPython repository to be the same as
   the upstream CPython repository.
 
+Please do not try to solve this by creating a pull request from
+``python:master`` to ``<username>:master`` as the authors of the patches will
+get notified unnecessarily.

 Solution::
 
    git checkout master
    git pull upstream master
    git push origin master
