+# Aero Echo
+
+A real-time flight tracking application that displays live aircraft movements on an interactive map.
+
+![alt text](image.png)
+
+## 🚀 Features
+
+- **Real-Time Tracking**: Watch aircraft positions update instantly with WebSocket connections
+- **Global Coverage**: Track flights worldwide with extensive ADS-B network coverage
+- **Live Data**: Access comprehensive flight details including altitude, speed, and heading
+- **Smart Filtering**: Flight data is filtered based on map zoom level and boundaries for optimal performance
+- **Responsive Design**: Works seamlessly on desktop and mobile devices
+
+## 🛠️ Technologies Used
+
+### Frontend
+
+- **Next.js** - React framework for optimized performance and seamless navigation
+- **Socket.IO Client** - WebSocket technology for real-time bidirectional communication
+- **Tailwind CSS** - Utility-first CSS framework for styling
+- **Lucide React** - Beautiful icon library
+
+### Backend
+
+- **Node.js** - JavaScript runtime environment
+- **Express** - Web application framework for Node.js
+- **Socket.IO** - Real-time event-based communication
+- **ADSB.one API** - Real-time aircraft data streaming
+
+## 📋 Prerequisites
+
+Before you begin, ensure you have the following installed:
+
+- Node.js (v18 or higher)
+- npm or yarn
+- Git
+
+### 🔧 Installation
+
+## ⚙️ Configuration
+
+### Backend Configuration
+
+Create a `.env` file in the backend directory:
+
+```env
+NODE_ENV=development
+PORT=3001
+```
+
+### Frontend Configuration
+
+Create a `.env.local` file in the frontend directory:
+
+```env
+NEXT_PUBLIC_API_URL=http://localhost:3001/api/v1
+NEXT_PUBLIC_SOCKET_SERVER_URL=http://localhost:3001
+```
+
+## 🚀 Running the Application
+
+```bash
+npm run dev
+```
+
+## 📡 API Limitations
+
+This application uses the ADSB.one API with the following constraints:
+
+- **Coverage Radius**: Limited to 250 nautical miles from a specific location
+- **Rate Limiting**: Maximum 1 request per second to the API
+- **Data Caching**: Server-side global variable caching is implemented to optimize performance and respect rate limits
+- **Smart Filtering**: Flight data is filtered based on map zoom level and boundaries to provide relevant information efficiently
+
+## 🏗️ Architecture
+
+### Data Flow
+
+1. Backend makes requests to ADSB.one API (max 1 req/sec)
+2. Flight data is cached in a global variable on the server
+3. Frontend connects to backend via Socket.IO
+4. Backend filters and sends relevant data based on map boundaries
+5. Frontend receives real-time updates and displays aircraft on the map
+
+### Caching Strategy
+
+To respect the API's 1 request/second limit, the backend:
+
+- Maintains a global cache of all aircraft data
+- Updates the cache once per second
+- Filters data based on client's map view
+- Pushes only relevant data to connected clients

+## 🐛 Known Issues
+
+- Coverage limited to 250nm radius from configured location
+- API rate limiting may cause delays during high traffic
+- Some aircraft may not appear if outside the coverage area
+

-
-## Getting Started
-
-First, run the development server:
-
-```bash
-npm run dev
-# or
-yarn dev
-# or
-pnpm dev
-# or
-bun dev
-```
