 # Web Stream Tools
 
-This library contains both basic convenience functions such as `readToEnd`, `concat`, `slice`, `clone`, `webToNode` and `nodeToWeb`, and more complex functions for transforming and parsing streams. Examples of the latter can be found below.

+### Stream support in Node.js
+
+From v0.1, **the library no longer supports native Node Readable streams in input**, and instead expects [Node's WebStreams](https://nodejs.org/api/webstreams.html#class-readablestream). [Node v17+ includes utilities to convert from and to Web Streams](https://nodejs.org/api/stream.html#streamreadabletowebstreamreadable-options).

 ### Transforming a stream
@@ -115,4 +120,3 @@ stream.clone(input); // Returns a copy of the stream so that two functions can r
 stream.passiveClone(input); // Also returns a copy of the stream, but doesn't return data immediately when you read from it, only returns data when you read from the original stream. This is meant for respecting backpressure.

-Note: these three functions do not work well with Node streams. Please convert Node streams to Web streams with `stream.nodeToWeb` first before using them.
