 * ``build_tunnels()``\ : which will start making the required amount of circuits for the given hop count
-* ``active_data_circuits()``\ : will return the currently available circuits to send data over
+* ``find_circuits()``\ : will return the currently available circuits to send data over
 * ``tunnels_ready()``\ : the quotient of available circuits to send over, compared to ``settings.min_circuits``
 * ``tunnel_data()``\ : which will send data to some destination through an exit node
-* ``register_service()``\ : which provide end-to-end connections for a particular service
+* ``join_swarm()``\ : which provide end-to-end connections for a particular service
 
 Note that you will have to call ``build_tunnels()`` before sending any data.
 For example ``build_tunnels(1)`` will construct 1 hop circuits to maintain a circuit pool of a size between ``settings.min_circuits`` and ``settings.max_circuits``.
 Initializing these settings will be covered in a later section.
 
 You can then call ``tunnel_data()`` to send data through a circuit (and eventually an exit node) to some destination.
-The circuit to send over should be one of the circuits returned by active_data_circuits().
+The circuit to send over should be one of the circuits returned by find_circuits().
 The destination can be any ip + port tuple.
 The message type should be ``u"data"`` and finally the payload can be an arbitrary message.
 For example one could send the packet ``1`` to ``("1.2.3.4", 5)``\ :
 
 .. code-block:: python
 
-   community.tunnel_data(community.active_data_circuits()[0], ("1.2.3.4", 5), u"data", "1")
+   community.tunnel_data(community.find_circuits()[0], ("1.2.3.4", 5), MyPayload("data"))

 To do this, some sort of DHT mechanism needs to be registered (currently Tribler uses mainline DHT).
 Whatever DHT mechanism is chosen should be placed in the ``dht_provider`` attribute of the ``HiddenTunnelCommunity``.
