 ## 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.

+## This module uses `pull-streams`
+
+We expose a streaming interface based on `pull-streams`, rather then on the Node.js core streams implementation (aka Node.js streams). `pull-streams` offers us a better mechanism for error handling and flow control guarantees. If you would like to know more about what took us to make this migration, see the discussion at this [issue](https://github.com/ipfs/js-ipfs/issues/362).

+### Converting `pull-streams` to Node.js Streams
+
+If you are a Node.js streams user, you can convert a pull-stream to Node.js Stream using the module `pull-stream-to-stream`, giving you an instance of a Node.js stream that is linked to the pull-stream. Example:
+
+```
+const pullToStream = require('pull-stream-to-stream')
+
+const nodeStreamInstance = pullToStream(pullStreamInstance)
+// nodeStreamInstance is an instance of a Node.js Stream
+```
