+# greatws
+A websocket library that allegedly can support massive connections, async in nature, supporting callbacks  
+A fork from https://github.com/antlabs/greatws  
+// 支持海量连接的websocket库，callback写法
+
+# Main Features
+//# 特性  
+* based on epoll/kqueue  
+//* 支持 epoll/kqueue  
+* low memory usage  
+//* 低内存占用  
+* high transaction (tps transactions per seconds) volume  
+//* 高tps  
+
+# Still todo    
+//# 暂不支持  
+* ssl
+* windows
+* io-uring
+
+# Warning  
+//# 警告⚠️  
+Early stages, production use is not recommended!  
+// 早期阶段，暂时不建议生产使用  
+
+# Example Server
+//# 例子-服务端
