+## About
+
+This is not the official branch. I'm maintaining this fork simply for
+maintenance (the original branch did not build with recent version of
+autoreconf). I'm *am not* actively developing pidgin-gpg, mainly making
 sure it keeps working and building. Releases > 0.9 should not be confused
 with those of the original author (though the original author seems to
 have stopped all development).
