-### var tcp = new Tcp()
+`libp2p-tcp` accepts TCP addresses both IPFS and non IPFS encapsulated addresses, i.e:
 
-Creates a new TCP object. This does nothing on its own, but provides access to
-`dial` and `createListener`.
+`/ip4/127.0.0.1/tcp/4001`
+`/ip4/127.0.0.1/tcp/4001/ipfs/QmHash`
 
-### tcp.createListener(multiaddrs, handler, ready)
-
-Creates TCP servers that listen on the addresses described in the array
-`multiaddrs`. Each connection will call `handler` with a connection stream.
-`ready` is called once all servers are listening.
-
-### tcp.dial(multiaddr, options={})
-
-Connects to the multiaddress `multiaddr` using TCP, returning the socket stream.
-If `options.ready` is set to a function, it is called when a connection is
-established.
-
-### tcp.close(callback)
-
-Closes all the listening TCP servers, calling `callback` once all of them have
-been shut down.
+Both for dialing and listening.
