+Please use this module instead of [mod_csi_pump] if you want timestamping,
+properly handled carbon copies, support for handling encrypted messages and
+correctly handled smacks events.
+
 Stanzas are queued in a buffer until either an "important" stanza is
 encountered or the buffer becomes full. Then all queued stanzas are sent
 at the same time. This way, nothing is lost or reordered while still
 allowing for power usage savings by not requiring mobile clients to
 bring up their radio for unimportant stanzas.
 
-`IQ` stanzas, smacks "stanzas" and `message` stanzas containing a body are
-considered important. Groupchat messages must set a subject or have
-the user's username or nickname in their messages to count as "important".
-`Presence` stanzas are not "important".
+`IQ` stanzas, and `message` stanzas containing a body or being encypted
+and all nonzas are considered important. Groupchat messages must set a
+subject or have the user's username or nickname in their messages to count
+as "important". `Presence` stanzas are always not "important".
 
 All buffered stanzas that allow timestamping are properly stamped to
 reflect their original send time, see [XEP-0203].
 
 Use with other CSI plugins such as [mod_throttle_presence],
 [mod_filter_chatstates] or [mod_csi_pump] is *not* supported.
-Please use this module instead of [mod_csi_pump] if you want timestamping
-and properly handled carbon copies.
 
 The internal stanza buffer of this module is hardcoded to 100 stanzas.
