+Supported browsers for the admin
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Django hasn't had a clear policy on which browsers are supported for using the
+admin app. Django's new policy formalizes existing practices: `YUI's A-grade`_
+browsers should provide a fully-functional admin experience, with the notable
+exception of IE6, which is no longer supported.
+
+Released over ten years ago, IE6 imposes many limitations on modern web
+development. The practical implications of this policy are that contributors
+are free to improve the admin without consideration for these limitations.
+
+This new policy **has no impact** on development outside of the admin. Users of
+Django are free to develop webapps compatible with any range of browsers.
