+</p>
 
-## Installation
+**SyncTasksManager** is a native JSI-based library for React Native that allows you to manage and execute background sync tasks (such as periodic API polling) efficiently from JavaScript, while delegating the actual execution to the native layer for better performance.
 
-```sh
-npm install react-native-sync-tasks
+---
+
+## ⚙️ Features
+
+- 🔁 Periodic HTTP polling with configurable interval
+- 📡 Callback on data reception or error
+- 🧵 High-performance task execution via JSI
+- 🧠 Centralized task management (start/stop all tasks)
+- ✅ Seamless integration with native modules (C++/JSI)
+
+---
+
+## 📦 Installation
+
+> You need to properly install and link the native JSI module `SyncTasksManager` on both iOS and Android.
+
+```bash
+# Install your native module here (replace with real package)
+npm install react-native-sync-tasks-manager
 ```
 
-## Usage
+> Don’t forget to run `pod install` for iOS if using CocoaPods.
+
+---
 
+## 🛠️ Usage
 
-```js
-import { multiply } from 'react-native-sync-tasks';
+```ts
+import { createTask, SyncTasksManager } from 'react-native-sync-tasks-manager';
 
-// ...
+const task = createTask<{ response: string }>({
+  config: {
+    url: 'https://jsonplaceholder.typicode.com/posts/1',
+    interval: 2000,
+    headers: {
+      'Content-Type': 'application/json',
+      'Accept': 'application/json',
+    },
+  },
+  onData: (data) => {
+    console.log('DATA', data);
+  },
+  onError: (error) => {
+    console.log('ERROR', error);
+  },
+});
 
-const result = multiply(3, 7);
+SyncTasksManager.addTask(task);
+SyncTasksManager.startAll();
 ```
