+## Support for controlling public registration and room auto-join
+
+The playbook now lets you enable public registration for users (controlled via `matrix_synapse_enable_registration`).
+By default, public registration is forbidden.
+
+You can also make people automatically get auto-joined to rooms (controlled via `matrix_synapse_auto_join_rooms`).
+
+## Support for changing the welcome user id (welcome bot)
+
+By default, `@riot-bot:matrix.org` is used to welcome newly registered users.
+This can be changed to something else (or disabled) via the new `matrix_riot_web_welcome_user_id` variable.
