+Vdirsyncer can currently download events from Google Calendar, but any
+writing/uploading is explicitly prohibited by Google. `Google's support forum
+<https://support.google.com/calendar/answer/99358>`_ explains how to set up its
+CalDAV support::
+
+    [storage cal]
+    type = caldav
+    url = https://www.google.com/calendar/dav/
+    username = ...
+    password = ...
+    read_only = true
