+# muc-presence-probe
+
+A [converse.js](https://conversejs.org) plugin which sends out `<presence>`
+stanzas of type `probe` whenever a message from an unknown author (i.e. one for
+which we don't have a [ChatRoomOccupant](https://conversejs.org/docs/html/api/-_converse.ChatRoomOccupant.html))
+is received.
+
+The goal of a presence probe is to fetch presence-related information (such as
+[XEP-317 Hats](https://xmpp.org/extensions/xep-0317.html).
+
+A supporting XMPP server will respond to a probe with the probed user's
+presence information.
+
+MUC presence probes are described in [XEP-0045 section 17.3](https://xmpp.org/extensions/xep-0045.html#bizrules-presence).
+
+Generally, this plugin will only make sense when you've disabled presences in a
+MUC, but stil want to fetch presence-related metadata for message authors.
