+  		When it comes to Twitter Direct Message you must specify who you sending this message to - <emphasis>target userid</emphasis>. 
+  		Twitter Outbound Direct Message Channel Adapter provides several ways you can specify target user.
+        By default it will look for target userid in the Message headers under the name <code>twitter_dmTargetUserId</code> which 
+        is also identified by the following constant - <classname>TwitterHeaders.DM_TARGET_USER_ID</classname>.
+		So when creating a Message all you need to do is add this header:
+		
+		<programlisting language="java"><![CDATA[Message message = MessageBuilder.withPayload("hello")
+		.setHeader(TwitterHeaders.DM_TARGET_USER_ID, "z_oleg").build();]]></programlisting>
+  		</para>
+  		<para>
+  		The above approach works well if you know the target userid in advance. However there are times when such 
+  		value must be determined dynamically. For those cases you can utilize SpEL support by providing valid SpEL 
+  		expression via <code>target-user-expression</code> attribute.
