+Writing Packets
 ~~~~~~~~~~~~~~~~~~~~
 
 The packet class uses a lot of magic to work, here is how to use them.
 Look up the particular packet you need to deal with, for my example let's go with the ``KeepAlivePacket``

+Listening for Certain Packets
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Let's look at how to listen for certain packets, the relevant method being

+.. automethod:: network.connection.Connection.register_packet_listener
+
+An example of this can be found in the ``start.py`` headless client, it is recreated here::
+
+    connection = Connection(address, port, login_response)
+    connection.connect()
+
+    def print_chat(chat_packet):
+        print "Position: " + str(chat_packet.position)
+        print "Data: " + chat_packet.json_data
+
+    from network.packets import ChatMessagePacket
+    connection.register_packet_listener(print_chat, ChatMessagePacket)
+
+The field names ``position`` and ``json_data`` are inferred by again looking at the definition attribute as before
