+summary: Advertise an external TURN service
+...
+
+This module advertises STUN/TURN service to clients via XEP-0215 (it utilizes
+mod_external_services to do so, which will be automatically loaded by this
+module and must be available).
+
+This module is included with Prosody 0.12 but made available here for older
+versions.
+
+Documentation is available on the [Prosody site][doc:modules:mod_turn_external].
