+# TeleBot - LittleShop Integration Summary
+
+## ✅ Completed Implementation
+
+### 1. **Privacy-First Architecture**
+- ✅ Anonymous user identification (SHA-256 hashed Telegram IDs)
+- ✅ Ephemeral sessions by default (30-minute timeout)
+- ✅ PGP encryption support for shipping information
+- ✅ Tor support for routing (SOCKS5 proxy configuration)
+- ✅ Zero-knowledge cart storage (encrypted with session keys)
+- ✅ Privacy-preserving logging (PII redaction)
+
+### 2. **Core Components Created**
+
+#### **Models** (`/Models/`)
+- `UserSession.cs` - Privacy-focused session management
+- `ShoppingCart.cs` - Cart and item management
+- `OrderFlowData.cs` - Checkout flow state tracking
+
+#### **Services** (`/Services/`)
+- `PrivacyService.cs` - Encryption, hashing, Tor client creation
+- `SessionManager.cs` - Session lifecycle with Redis/LiteDB support
+- `LittleShopService.cs` - Wrapper for LittleShop Client SDK
+
+#### **Handlers** (`/Handlers/`)
+- `CommandHandler.cs` - Telegram command processing (/start, /browse, etc.)
+- `CallbackHandler.cs` - Button interaction handling
+- `MessageHandler.cs` - Text message processing (checkout flow)
+
+#### **UI Components** (`/UI/`)
+- `MenuBuilder.cs` - Dynamic Telegram keyboard generation
+- `MessageFormatter.cs` - Rich text formatting for products/orders
+
+### 3. **Features Implemented**
+
+#### **Shopping Flow**
+1. Browse categories → View products → Product details
+2. Add to cart with quantity selection
+3. Cart management (view, update, clear)
+4. Multi-step checkout (name, address, city, postal, country)
+5. Payment method selection (8 cryptocurrencies)
+6. Order confirmation with payment instructions
+7. QR code generation for crypto addresses
+
+#### **Privacy Features**
+- `/ephemeral` - Toggle ephemeral mode
+- `/pgpkey` - Set PGP public key
+- `/delete` - Instant data deletion
+- `/tor` - Tor configuration guide
+- `/privacy` - Privacy settings menu
+
+#### **Order Management**
+- Anonymous order references (ANON-XXXXXXXXXXXX)
+- Order history viewing
+- Payment status tracking
+- Shipping status updates
+
+### 4. **Configuration System**
+
+#### **appsettings.json Structure**
+```json
+{
+  "Telegram": { "BotToken": "..." },
+  "LittleShop": { "ApiUrl": "...", "UseTor": false },
+  "Privacy": { "EphemeralByDefault": true, "EnableTor": false },
+  "Redis": { "Enabled": false },
+  "Features": { "EnableQRCodes": true, "EnablePGPEncryption": true }
+}
+```
+
+### 5. **Dependencies Integrated**
+- ✅ LittleShop.Client SDK
+- ✅ Telegram.Bot framework
+- ✅ PgpCore for encryption
+- ✅ LiteDB for local storage
+- ✅ Redis for distributed cache
+- ✅ QRCoder for payment QR codes
+- ✅ Serilog for logging
+- ✅ Hangfire for background jobs
+
+## 🔧 Integration Points
+
+### **LittleShop Client SDK Usage**
+```csharp
+// Authentication
+await _client.Authentication.LoginAsync(username, password);
+
+// Fetch categories
+var categories = await _client.Catalog.GetCategoriesAsync();
+
+// Get products
+var products = await _client.Catalog.GetProductsAsync(categoryId: id);
+
+// Create order
+var order = await _client.Orders.CreateOrderAsync(request);
+
+// Generate payment
+var payment = await _client.Orders.CreatePaymentAsync(orderId, currency);
+```
+
+### **Privacy Implementation**
+```csharp
+// Anonymous user identification
+var hashedId = SHA256(telegramUserId + salt);
+
+// PGP encryption for shipping

+    "EnableTor": true,
+    "TorSocksPort": 9050,
+    "TorControlPort": 9051
+  }
+}
+```
+
+### Redis Session Storage (Optional)
+For non-ephemeral sessions across bot restarts:
+```json
+{
+  "Redis": {
+    "Enabled": true,
+    "ConnectionString": "localhost:6379",
+    "InstanceName": "TeleBot"
+  }
+}
+```
+
+## 🧅 Tor Setup
+
+### 1. Install Tor
+```bash
+# Ubuntu/Debian
+sudo apt install tor
+
+# Start Tor service
+sudo systemctl start tor
+```
+
+### 2. Configure Hidden Service

+```
+HiddenServiceDir /var/lib/tor/telebot/
+HiddenServicePort 80 127.0.0.1:5000
+HiddenServiceVersion 3
+```
+
+### 3. Get Onion Address
+```bash
+sudo cat /var/lib/tor/telebot/hostname
+```
+
+### 4. Configure Bot
+```json
+{
+  "Privacy": {
+    "EnableTor": true,
+    "OnionServiceDirectory": "/var/lib/tor/telebot/"
+  },
+  "LittleShop": {
