+PyCon US Code of Conduct
+========================
 
-This is a "fork" of the 2013 PyCon code of conduct including the staff and attendee guides. 
+This repository holds the canonical version of the PyCon US Code of Conduct.
 
-Thank you to Adria Richards and many others with the Python Software Foundation and Python community for recommending
-that we publicly discuss and version control these documents so changes can be suggested, wording corrected and we can
-continue to iterate, as a community on these policies and procedures.
-
-PyCon and the community as a whole are still very much in a learning process, the conference is 11 years old and still
-evolving daily. Each year we see massive improvements (such as the code of conduct and staff procedures) and PyCon 2013
-was no different.
-
-We hope, as a team we can iterate and improve continually.
-
-No changes are final until approved by the PyCon Chair / Staff and versions in place for a given year will be clearly
-marked, the website contents on us.pycon.org will clearly state the revision of the documents posted.
