-> Node.js implementation of the TCP module that libp2p uses, which implements
-> the [interface-connection](https://github.com/diasdavid/interface-connection)
-> interface for dial/listen.
 
-## Description
+> JavaScript implementation of the TCP module for libp2p. It exposes the [interface-transport](https://github.com/libp2p/interface-connection) for dial/listen. `libp2p-tcp` is a very thin shim that adds support for dialing to a `multiaddr`. This small shim will enable libp2p to use other different transports.

 ## API
 
-```js
+### Transport
-const Tcp = require('libp2p-tcp')
-```
 
-### var tcp = new Tcp()
+[![](https://raw.githubusercontent.com/libp2p/interface-transport/master/img/badge.png)](https://github.com/libp2p/interface-transport)
 
-Creates a new TCP object. This does nothing on its own, but provides access to
+`libp2p-tcp` accepts TCP addresses both IPFS and non IPFS encapsulated addresses, i.e:
-`dial` and `createListener`.
 
-### tcp.createListener(multiaddrs, handler, ready)
+`/ip4/127.0.0.1/tcp/4001`
+`/ip4/127.0.0.1/tcp/4001/ipfs/QmHash`
 
-Creates TCP servers that listen on the addresses described in the array
+Both for dialing and listening.
-`multiaddrs`. Each connection will call `handler` with a connection stream.
-`ready` is called once all servers are listening.
 
-### tcp.dial(multiaddr, options={})
+### Connection
 
-Connects to the multiaddress `multiaddr` using TCP, returning the socket stream.
+[![](https://raw.githubusercontent.com/libp2p/interface-connection/master/img/badge.png)](https://github.com/libp2p/interface-connection)
-If `options.ready` is set to a function, it is called when a connection is
-established.
 
-### tcp.close(callback)
+## Contribute
 
-Closes all the listening TCP servers, calling `callback` once all of them have
+Contributions are welcome! The libp2p implementation in JavaScript is a work in progress. As such, there's a few things you can do right now to help out:
-been shut down.
