+## Chunked transfer encoding
+
+Actix automatically decode *chunked* encoding. `HttpRequest::payload()` already contains
+decoded bytes stream. If request payload compressed with one of supported
+compression codecs (br, gzip, deflate) bytes stream get decompressed.
+
+Chunked encoding on response could be enabled with `HttpResponseBuilder::chunked()` method.
+But this takes effect only for `Body::Streaming(BodyStream)` or `Body::StreamingContext` bodies.
+Also if response payload compression is enabled and streaming body is used, chunked encoding
+get enabled automatically.
+
+Enabling chunked encoding for *HTTP/2.0* responses is forbidden.
