+Prosody
+-------
+
+The ``prosody`` role can be used for setting-up Prosody, an XMPP server, on
+destination machine.
+
+The role implements the following:
+
+* Sets-up the Prosody apt repository.
+* Installs Prosody.
+* Configures Prosody.
+
+Prosody is configured as follows:
+
+* Modules enabled: roster, saslauth, tls, dialback, posix, private, vcard,
+  version, uptime, time, ping, pep, register, admin_adhoc, announce.
+* Self-registration is not allowed.
+* TLS is configured.
+* Client-to-server communication requires encryption (TLS).
+* Authentication is done via LDAP. For setting the LDAP TLS truststore, see
+  :ref:`LDAP Client <ldap_client>`.
+* Internal storage is used.
+* For each domain specified, a dedicated conference/multi-user chat (MUC)
+  service is set-up, with FQDN set to ``conference.DOMAIN``.
+* For each domain specified, a dedicated file proxy service will be set-up, with
+  FQDN set to ``proxy.DOMAIN``.
