-High-level wrappers for Ruby sockets with advanced thread-safe timeout support.
+High-level Ruby socket library with support for TCP, UDP, and SSL sockets.
 
-**Does not require Celluloid!** Socketry provides sockets with thread-safe

+Implements thread-safe timeouts using asynchronous I/O and high-precision monotonic timers.
 
 ## Motivation
 
 By default, Ruby sockets do not provide a built-in timeout mechanism. The only
 timeout mechanism provided by the language leverages [timeout.rb], which uses
