+
+Introduction
+============
+
+`mod_offline` does not take into account XEP-334 tags.  This module
+will not add to the offline storage those messages tagged with
+`<no-store />`.
+
+Usage
+=====
+
+First copy the module to the prosody plugins directory.
+
+Then add "offline\_hints" to your modules\_enabled list in your
+configuration.
+
+No configuration options are available.
