+At first run you will be asked to authorize application for google account
+access. Simply follow the instructions. You'll be asked to modify configuration
+file (save `refresh_token` as a password).

+- Google's CardDav implementation is very limited, may lead to data loss, use
+  with care.
+- You can select which calendars to sync on
+  `CalDav settings page <https://calendar.google.com/calendar/syncselect>`_
