+This repo holds scripts related to managing Google Summer of Code for the Python Software Foundation
+
+The issues tracker is used to help us keep track of ideas we have for
+improving the programme.  Please feel free to make suggestions there,
+although do remember that we have only limited volunteer time and
+availability, so not every great idea is likely to get implemented.
+
+Help with implementing these ideas is very much appreciated!
