+## Description
+
+`libp2p-tcp` in Node.js is a very thin shim that adds support for dialing to a
+`multiaddr`. This small shim will enable libp2p to use other different
+transports.
+
+## Example
+
+```js
+const Tcp = require('libp2p-tcp')
+const multiaddr = require('multiaddr')
+
+const mh1 = multiaddr('/ip4/127.0.0.1/tcp/9090')
+const mh2 = multiaddr('/ip6/::/tcp/9092')
+
+const tcp = new Tcp()
+
+tcp.createListener([mh1, mh2], function handler (socket) {
+  console.log('connection')
+  socket.end('bye')
+}, function ready () {
+  console.log('ready')
+
+  const client = tcp.dial(mh1)
+  client.pipe(process.stdout)
+  client.on('end', () => {
+    tcp.close()
+  })
+})
+
+```
+
+outputs
+
+```
+ready
+connection
+bye
+```
+
+## Installation
+
+### npm
+
+```sh
+> npm i libp2p-tcp
+```
+
+## API
+
+```js
+const Tcp = require('libp2p-tcp')
+```
+
+### var tcp = new Tcp()
+
+Creates a new TCP object. This does nothing on its own, but provides access to
+`dial` and `createListener`.
+
+### 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.
