-Simple multicast UDP message client and server for [ReactPHP](https://reactphp.org/).
+Simple, event-driven multicast UDP message client and server for [ReactPHP](https://reactphp.org/).
 
 Multicast UDP messages are needed for quite a few (low-level) networking protocols.
+Among others, multicast networking is the basis for mDNS (Multicast DNS),
+HTTPMU (Multicast UDP HTTP Messages), UPnP/SSDP (Universal Plug and Play /
+Simple Service Discovery Protocol) and others.
 This library exposes a simple subset of commonly needed functionality for
 multicast networking through an easy to use API.
 
-Among others, multicast networking is the basis for:
-
-* MDNS (Multicast DNS)
-* HTTPU/HTTPMU (Multicast and Unicast UDP HTTP Messages)
-* UPNP/SSDP (Univeral Plug and Play / Simple Service Discovery Protocol).
