 Event-driven, streaming HTTP client for [ReactPHP](https://reactphp.org).
 
+> Note that this is a very low-level HTTP client implementation that is currently
+  undergoing some major changes. In the meantime, we recommend using
+  [clue/reactphp-buzz](https://github.com/clue/reactphp-buzz) as a higher-level
+  HTTP client abstraction (which happens to build on top of this project). It
+  provides a Promise-based interface and common PSR-7 message abstraction which
+  makes getting started much easier.
