 # safe-web-socket
 
+> A secure, production-ready WebSocket wrapper for Go with built-in validation, rate limiting, authentication, and connection management.
+
+## Overview
+
+`SafeWebSocket` is a Go library designed to simplify the creation of **secure, scalable, and resilient WebSocket servers**. Built on top of `gorilla/websocket`, it adds essential safety layers — including authentication, input validation, connection limits, rate limiting, and graceful shutdown — so you can focus on your application logic, not security pitfalls.
+
+Whether you’re building real-time dashboards, chat apps, or live data feeds, `SafeWebSocket` ensures your WebSocket endpoints are protected against common attacks (e.g., DoS, injection, unauthorized access).
+
+## Features
+- ✅ **Graceful Shutdown & Cleanup**
+- ✅ **Automatic Reconnection Handling (Client-side helpers)**
+- ✅ **WebSocket Ping/Pong Health Checks**
+
+## Installation
+
+```bash
+go get git.neurocipta.com/rogerferdinan/safe-web-socket
+```
+
+> Requires Go 1.24+
