-This is a [Next.js](https://nextjs.org) project bootstrapped with [`create-next-app`](https://nextjs.org/docs/app/api-reference/cli/create-next-app).
+# GroupPot - Social Betting Platform
 
-## Getting Started
+A sophisticated group betting platform built with Next.js that enables friends and communities to create and participate in custom betting pools with advanced settlement logic and comprehensive analytics.
 
-First, run the development server:
+## 🎯 Features
 
-```bash
-npm run dev
-# or
-yarn dev
-# or
-pnpm dev
-# or
-bun dev
-```
+### Core Betting System
+- **Multi-format Betting**: Support for single-choice and multi-choice bets
+- **Advanced Settlement Logic**: 
+  - Exact match betting (all selections must be correct)
+  - Partial match betting (proportional payouts for partially correct selections)
+  - Automatic refund system when no winners exist
+- **Dynamic Payout Calculation**: Pool-based profit distribution with proportional stake allocation
+- **Flexible Stake Management**: Configurable minimum and maximum stake limits per bet
 
-Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.
+### Group Management
+- **Private Group Creation**: Invite-only groups with unique access codes
+- **Role-based Permissions**: Owner and moderator roles with different privileges
+- **Member Analytics**: Comprehensive statistics including win rates, profit/loss, and betting history
+- **Group-specific Analytics**: Track performance across different betting communities
 
-You can start editing the page by modifying `app/page.tsx`. The page auto-updates as you edit the file.
+### User Experience
+- **Real-time Updates**: Auto-refreshing data with manual refresh controls
+- **Comprehensive Dashboard**: Personal betting portfolio with performance metrics
+- **Detailed Betting History**: Complete transaction history with profit/loss tracking
+- **Responsive Design**: Mobile-first design with adaptive layouts
+- **Interactive Charts**: Visual representation of betting performance over time
 
-This project uses [`next/font`](https://nextjs.org/docs/app/building-your-application/optimizing/fonts) to automatically optimize and load [Geist](https://vercel.com/font), a new font family for Vercel.
+### Security & Authentication
+- **JWT-based Authentication**: Secure token-based user sessions
+- **Password Reset System**: Email-based password recovery
+- **Account Management**: Complete user profile and account deletion capabilities

+- MongoDB Atlas account
+- SMTP email service (for password reset)
+
+### Installation
+
+1. **Clone the repository**
+   ```bash
+   git clone <repository-url>
+   cd my-app
+   ```
+
+2. **Install dependencies**
+   ```bash
+   npm install
+   ```
+
+3. **Environment Setup**
+   Create a `.env.local` file with the following variables:
+   ```env
+   MONGODB_URI=your_mongodb_atlas_connection_string
+   JWT_SECRET=your_jwt_secret_key
+   EMAIL_HOST=your_smtp_host
+   EMAIL_PORT=your_smtp_port
+   EMAIL_USER=your_email_username
+   EMAIL_PASS=your_email_password
+   EMAIL_FROM=your_from_email_address
+   ```
+
+4. **Run the development server**

+
+## 📊 Key Architecture Decisions
+
+### Database Design
+- **User Management**: Secure user profiles with encrypted passwords
+- **Group System**: Hierarchical group structure with member roles
+- **Betting Logic**: Flexible bet schema supporting multiple voting types

+- **Stake Splitting**: Complex calculation for partial match scenarios
+
+### Performance Optimizations
+- **SWR Caching**: Efficient data fetching with automatic revalidation
+- **Auto-refresh System**: Smart polling with user activity detection
+- **Responsive Loading**: Skeleton screens and progressive loading
+- **Error Boundaries**: Graceful error handling throughout the application

+# Authentication Setup Guide
+
+## Environment Variables
+
+Create a `.env` file in your project root with the following variables:
+
+```env
+# Email Configuration (Gmail)
+EMAIL_USER=your-email@gmail.com
+EMAIL_PASSWORD=your-app-password
+
+# JWT Secret (change this in production)
+JWT_SECRET=49aa564ea09390f8dd2d5aeb0d1558c78c568a6f672e4abae188f40f08574ec396dccdc7eaefdc6848c59455ec58b14b4dcbf619cbce51ec6369baabec053d5f
+
+# App URL (for email links)
+NEXT_PUBLIC_APP_URL=http://localhost:3000
+
+# MongoDB Atlas Connection String (includes database name)
+MONGODB_URI=mongodb+srv://rcommandur:Cu44ent2005@cluster0.vyw4kan.mongodb.net/GroupPot?retryWrites=true&w=majority&appName=Cluster0
+```
+
+## MongoDB Atlas Setup
+
+### 1. Create MongoDB Atlas Account
+1. Go to [MongoDB Atlas](https://www.mongodb.com/atlas)
+2. Click "Try Free" or "Get Started Free"
+3. Fill in your details and create an account
+
+### 2. Create a New Cluster
+1. Click "Build a Database"
+2. Choose "FREE" tier (M0)
+3. Select your preferred cloud provider (AWS, Google Cloud, or Azure)
+4. Choose a region close to you
+5. Click "Create"
+
+### 3. Set Up Database Access
+1. In the left sidebar, click "Database Access"
+2. Click "Add New Database User"
+3. Choose "Password" authentication
+4. Create a username and password (save these!)
+5. Set privileges to "Read and write to any database"
+6. Click "Add User"
+
+### 4. Set Up Network Access
+1. In the left sidebar, click "Network Access"
+2. Click "Add IP Address"
+3. For development, click "Allow Access from Anywhere" (0.0.0.0/0)
+4. Click "Confirm"
+
+### 5. Get Your Connection String
+1. Go back to "Database" in the sidebar
+2. Click "Connect"
+3. Choose "Connect your application"
+4. Select "Node.js" driver
+5. Copy the connection string and replace username/password
+6. **Important**: Add `/GroupPot` after `.net/` to specify the database name
+
+## Database Creation
+
+**You don't need to manually create a database!** Mongoose will automatically:
+- Create the `GroupPot` database when you first save data
+- Create collections (`users`, `groups`, `bets`) when you first insert documents
+- Set up proper indexes and validation
+
+## JWT Secret Generation
+
+I've generated a secure JWT secret for you above. If you want to generate a new one, you can:
+
+1. **Using Node.js** (if you have it installed):
+   ```bash
+   node -e "console.log(require('crypto').randomBytes(64).toString('hex'))"
+   ```
+
+2. **Using an online generator** (for development only):
+   - Visit https://generate-secret.vercel.app/64
+   - Copy the generated string
+
+3. **Using PowerShell** (Windows):
+   ```powershell
+   $bytes = New-Object Byte[] 64
+   (New-Object Security.Cryptography.RNGCryptoServiceProvider).GetBytes($bytes)
+   [System.BitConverter]::ToString($bytes) -replace '-', ''
+   ```
+
+**Important**: Use a different JWT secret for production environments!
+
+## Gmail App Password Setup
+
+To use Gmail for sending emails, you need to:
+
+1. Enable 2-Factor Authentication on your Google account
+2. Generate an App Password:
+   - Go to Google Account settings
+   - Security → 2-Step Verification → App passwords
+   - Generate a new app password for "Mail"
+   - Use this password in your `EMAIL_PASSWORD` environment variable
+

+## Sample Users
+
+The system comes with two sample users for testing:
+
+- **Email**: john@example.com, **Password**: password123
+- **Email**: jane@example.com, **Password**: password123
+
+## API Endpoints
+

+- `GET /api/auth/me` - Get current user profile
+- `POST /api/auth/logout` - User logout
+- `POST /api/auth/forgot-password` - Request password reset
+- `POST /api/auth/reset-password` - Reset password with token
+
+## Next Steps
