-Login, Send a Message, and Disconnect
-=====================================
+Sign in, Send a Message, and Disconnect
+=======================================
+
+.. note::
+    
+    If you have any issues working through this quickstart guide
+    or the other tutorials here, please either send a message to the
+    `mailing list <http://groups.google.com/group/sleekxmpp-discussion>`_
+    or join the chat room at `sleek@conference.jabber.org
+    <xmpp:sleek@conference.jabber.org?join>`_.
 
 A common use case for SleekXMPP is to send one-off messages from
-time to time. 
+time to time. For example, one use case could be sending out a notice when 
+a shell script finishes a task.
+
+We will create our one-shot bot based on the pattern explained in :ref:`echobot`. To
+start, we create a client class based on :class:`ClientXMPP <sleekxmpp.clientxmpp.ClientXMPP>` and
+register a handler for the :term:`session_start` event. We will also accept parameters
+for the JID that will receive our message, and the string content of the message.
+
+.. code-block:: python
+
+    import sleekxmpp
+
+
+    class SendMsgBot(sleekxmpp.ClientXMPP):
+        
+        def __init__(self, jid, password, recipient, msg):
+            super(SendMsgBot, self).__init__(jid, password)
+
+            self.recipient = recipient
+            self.msg = msg
+
+            self.add_event_handler('session_start', self.start)
+
+        def start(self, event):
+            self.send_presence()
+            self.get_roster()
+
+Note that as in :ref:`echobot`, we need to include send an initial presence and request
+the roster. Next, we want to send our message, and to do that we will use :meth:`send_message <sleekxmpp.basexmpp.BaseXMPP.send_message>`.
+
+.. code-block:: python
+
+    def start(self, event):
+        self.send_presence()
+        self.get_roster()
+
+        self.send_message(mto=self.recipient, mbody=self.msg)
+
+Finally, we need to disconnect the client using :meth:`disconnect <sleekxmpp.xmlstream.XMLStream.disconnect>`.
+Now, sent stanzas are placed in a queue to pass them to the send thread. If we were to call
+:meth:`disconnect <sleekxmpp.xmlstream.XMLStream.disconnect>` without any parameters, then it is possible
+for the client to disconnect before the send queue is processed and the message is actually
+sent on the wire. To ensure that our message is processed, we use 
+:meth:`disconnect(wait=True) <sleekxmpp.xmlstream.XMLStream.disconnect>`.
+
+.. code-block:: python
+
+    def start(self, event):
+        self.send_presence()
+        self.get_roster()
+
+        self.send_message(mto=self.recipient, mbody=self.msg)
+
+        self.disconnect(wait=True)
+
+.. warning::
+
+    If you happen to be adding stanzas to the send queue faster than the send thread
+    can process them, then :meth:`disconnect(wait=True) <sleekxmpp.xmlstream.XMLStream.disconnect>`
+    will block and not disconnect.
+
+Final Product
+-------------
+
+.. compound::
+
+    The final step is to create a small runner script for initialising our ``SendMsgBot`` class and adding some
+    basic configuration options. By following the basic boilerplate pattern in :ref:`echobot`, we arrive
+    at the code below. To experiment with this example, you can use:
+
+    .. code-block:: sh
+
+            python send_client.py -d -j oneshot@example.com -t someone@example.net -m "This is a message"
+
+    which will prompt for the password and then log in, send your message, and then disconnect. To test, open
+    your regular IM client with the account you wish to send messages to. When you run the ``send_client.py``
+    example and instruct it to send your IM client account a message, you should receive the message you
+    gave. If the two JIDs you use also have a mutual presence subscription (they're on each other's buddy lists)
+    then you will also see the ``SendMsgBot`` client come online and then go offline.
