+# MY Network v2.0 - Deployment Guide
+
+## 🎯 Обзор
+
+MY Network v2.0 - это распределенная P2P сеть для репликации контента с Matrix-мониторингом и полной автоматизацией развертывания.
+
+### Компоненты системы:
+- **MY Network Core** - основной P2P протокол (порт 15100)
+- **Web2 Client** - веб-интерфейс (порт 3000)
+- **Converter Module** - модуль конвертации (порт 8080)
+- **Telegram Bots** - клиентский и uploader боты (опционально)
+
+## 🚀 Типы развертывания
+
+### 1. Main Bootstrap Node (my-public-node-3.projscale.dev)
+
+**Назначение:** Главная нода сети, к которой подключаются все остальные ноды.
+
+**Скрипт:** [`deploy_main_bootstrap_node.sh`](deploy_main_bootstrap_node.sh)
+
+**Выполнение:**
+```bash
+# На сервере my-public-node-3.projscale.dev как root:
+chmod +x deploy_main_bootstrap_node.sh
+./deploy_main_bootstrap_node.sh
+```
+
+**Что делает:**
+- ✅ Устанавливает Docker + Docker Compose
+- ✅ Настраивает UFW firewall (22, 80, 443, 15100)
+- ✅ Настраивает Nginx reverse proxy
+- ✅ Получает SSL сертификат Let's Encrypt
+- ✅ Развертывает все компоненты (MY Network + Web Client + Converter)
+- ✅ Создает systemd service
+- ✅ Настраивает автообновление SSL
+
+**Результат:**
+- 🌐 **Web Interface:** https://my-public-node-3.projscale.dev/
+- 🎛️ **Matrix Dashboard:** https://my-public-node-3.projscale.dev/monitor/
+- ❤️ **Health Check:** https://my-public-node-3.projscale.dev/health
+- 🔗 **Bootstrap API:** https://my-public-node-3.projscale.dev/api/bootstrap
+- 🔌 **WebSocket:** wss://my-public-node-3.projscale.dev/ws/monitor
+
+### 2. Regular Node (подключение к сети)
+
+**Назначение:** Обычная нода, которая подключается к существующей сети.
+
+**Скрипт:** [`deploy_regular_node.sh`](deploy_regular_node.sh)
+
+**Выполнение:**
+```bash
+chmod +x deploy_regular_node.sh
+./deploy_regular_node.sh
+```
+
+**Интерактивная настройка:**
+1. **Node Name** - имя ноды (по умолчанию: my-node-timestamp)
+2. **Public Domain** - публичный домен (опционально для приватных нод)
+3. **Telegram Bot Token** - токен клиентского бота (опционально)
+4. **Uploader Bot Token** - токен uploader бота (опционально)
+
+**Типы нод:**
+- **Public Regular Node** - с доменом, SSL, Nginx, веб-интерфейсом
+- **Private Regular Node** - только локальный доступ, без публичного домена
+
+**Что делает:**
+- 🔍 Подключается к main bootstrap node
+- 📡 Получает конфигурацию сети
+- 🐳 Развертывает контейнеры согласно типу ноды
+- 🌐 Настраивает публичный доступ (если указан домен)
+- 🤖 Включает Telegram ботов (если указаны токены)
+- 🔄 Инициирует синхронизацию с сетью
+
+## 📋 Управление нодами
+
+### Main Bootstrap Node
+```bash
+# Просмотр логов
+docker-compose -f /opt/my-network-bootstrap/docker-compose.yml logs -f
+
+# Перезапуск
+systemctl restart my-network-main
+
+# Статус
+systemctl status my-network-main
+
+# Контейнеры
+docker-compose ps
+```
+
+### Regular Node
+```bash
+# Просмотр логов (замените NODE_NAME на имя вашей ноды)
+docker-compose -f /opt/my-network-NODE_NAME/docker-compose.yml logs -f
+
+# Перезапуск
+systemctl restart my-network-NODE_NAME
+
+# Статус
+systemctl status my-network-NODE_NAME
+```
+
+## 🔧 Конфигурация
+
+### Основные файлы:
+- **`.env`** - переменные окружения
+- **`bootstrap_main.json`** / **`bootstrap_regular.json`** - конфигурация ноды
+- **`docker-compose.yml`** - конфигурация контейнеров
+
+### Порты:
+- **15100** - MY Network Protocol v2.0
+- **3000** - Web2 Client (только для публичных нод)
+- **8080** - Converter Module
+- **80/443** - HTTP/HTTPS (Nginx)
+
+### Firewall (UFW):
+```bash
+# Основные порты
+ufw allow 22/tcp    # SSH
+ufw allow 80/tcp    # HTTP
+ufw allow 443/tcp   # HTTPS
+ufw allow 15100/tcp # MY Network
+```
+

+API_TITLE = "My Uploader Bot API"
+API_VERSION = "2.0.0"
+API_DESCRIPTION = """
+# My Uploader Bot API
+
+A comprehensive file upload and management system with blockchain integration.
+
+## Features
+
+- **File Upload & Management**: Chunked uploads, multiple storage backends, file processing
+- **User Authentication**: JWT tokens, API keys, sessions management
+- **Blockchain Integration**: TON blockchain wallet management, transactions
+- **Content Management**: Version control, metadata, search functionality
+- **Security**: Rate limiting, CORS, input validation, file encryption
+- **Monitoring**: Prometheus metrics, structured logging, health checks
+
+## Authentication
+
+The API supports multiple authentication methods:
+
+1. **JWT Bearer Token**: Use `Authorization: Bearer <token>` header
+2. **API Key**: Use `X-API-Key: <api_key>` header
+3. **Session Cookie**: Browser-based authentication
+
+## Rate Limiting
+
+API endpoints are rate-limited based on user tier:
+- Free tier: 100 requests per hour
+- Premium tier: 1000 requests per hour
+- Enterprise tier: 10000 requests per hour
+
+## File Upload Process
+
+1. **Initiate Upload**: POST `/api/v1/storage/upload/initiate` with file metadata
+2. **Upload Chunks**: POST `/api/v1/storage/upload/chunk` for each chunk
+3. **Complete Upload**: POST `/api/v1/storage/upload/complete` to finalize
+4. **Processing**: File is automatically processed in the background
+
+## Error Handling
+
+All errors follow RFC 7807 Problem Details format:
+
+```json
+{
+    "type": "https://api.myuploader.com/errors/validation",
+    "title": "Validation Error",
+    "status": 422,
+    "detail": "The request body contains invalid data",
+    "instance": "/api/v1/content/upload",
+    "errors": [
+        {
+            "field": "file_size",
+            "message": "File size exceeds maximum limit"
+        }
+    ]
+}
+```
+
+## Webhook Events
+
+The API can send webhook notifications for:
+- File upload completion
+- Processing status updates
+- Blockchain transaction confirmations
+- User subscription changes
+
+## SDKs and Examples
+
+- Python SDK: `pip install myuploader-python`
+- JavaScript SDK: `npm install @myuploader/js-sdk`
