-### 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 why we did this, see the discussion at this [issue](https://github.com/ipfs/js-ipfs/issues/362).

-You can learn more about pull-streams at:

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