+
+## Introduction
+
+This library provides **type-safe WebSocket communication** with a request-response and notification system built on top of a flexible protocol.  
+It ensures compile-time guarantees for message structure, reduces runtime errors, and simplifies building Rust client/server applications.
+
+- **Dynamic Methods**: Each message includes a method enum for type safety.
+- **Typed Requests & Responses**: Automatic serialization and deserialization.
+- **Optional Notifications**: Send asynchronous notifications across sessions.
+
+## Features
+
+- Fully typed WebSocket sessions
+- Type-safe request/response mechanism
+- Optional typed notifications (Todo)
+- Lightweight, minimal runtime overhead
+
+## Installation
+
+```bash
+cargo add session-rs
+```
+
+---
+
+### **Basic Example (client)**
+
+```java
+Session session = Session.connect("ws://localhost:8080/");
+
+TextNode response = session.request(Methods.Data, TextNode.valueOf("Hello from client")).get();
+
+System.out.println(response);
+
+session.close();
+```
+
+### **Basic Example (server)**
+
+#### ⚠️ Server functionality not done yet this is only for future examples
+
+```java
+SessionServer server = SessionServer.bind("ws://localhost:8080/");
+
+server.onClient((session, addr) -> {
+    session.onRequest(Methods.Data, (id, data) -> {
+        return SessionResult.ok(TextNode.valueOf("Response from server"));
+    });
+});
+```
+
+## Protocol
+
+#### Request
+
+The request `id` is separated from the peer, and will increment only on it's requests.
+
+```json
+{ "type": "request", "id": 1, "method": "data", "data": "Hello from client" }
+```
+
+#### Response
+
+The response `id` **must** remain the same as the request.
+
+```json
+{ "type": "response", "id": 1, "result": "Hello from server" }
+```
+
+#### Notifications
+
+A notification is a method that doesn't need validation or output, it simply notifies a peer for a specific information
+
+```json
+{ "type": "notification", "result": "Hello from server" }
+```
