+5. [Автоматический деплой](#автоматический-деплой)
+
+---
+
+## Создание репозитория
+
+### 1. Инициализация Git
+
+```bash
+# В корне проекта
+cd c:\Users\ormix\StudioProjects\NANAXE
+git init
+
+# Добавьте .gitignore
+echo "# Flutter/Dart
+.dart_tool/
+.flutter-plugins
+.flutter-plugins-dependencies
+.packages
+.pub-cache/
+.pub/
+build/
+*.g.dart
+*.freezed.dart
+
+# IDE
+.idea/
+.vscode/
+*.iml
+*.ipr
+*.iws
+
+# Environment
+.env
+.env.local
+
+# Server
+server/node_modules/
+server/logs/
+server/backups/
+*.log
+
+# OS
+.DS_Store
+Thumbs.db
+" > .gitignore
+
+# Первый коммит
+git add .
+git commit -m "Initial commit: Nanaxe CRM with server"
+```
+
+### 2. Создание репозитория на GitHub
+
+```bash
+# Создайте репозиторий на GitHub (через веб-интерфейс)
+# Затем:
+
+git remote add origin https://github.com/YOUR_USERNAME/nanaxe-crm.git
+git branch -M main
+git push -u origin main
+```
+
+---
+
+## Настройка Secrets
+
+Перейдите в **Settings → Secrets and variables → Actions** и добавьте:
+
+### Обязательные Secrets
+
+| Secret Name | Description | Example |
+|-------------|-------------|---------|
+| `VPS_HOST` | IP или домен VPS | `203.0.113.1` или `nanaxe.example.com` |
+| `VPS_USER` | SSH пользователь | `root` или `deploy` |
+| `VPS_SSH_KEY` | Приватный SSH ключ | Содержимое `~/.ssh/id_rsa` |
+| `DEPLOY_PATH` | Путь на сервере | `/opt/nanaxe-server` |
+
+### Опциональные Secrets
+
+| Secret Name | Description |
+|-------------|-------------|
+| `GITEA_DOMAIN` | Домен для Gitea |
+| `GITEA_TOKEN` | API токен Gitea |
+| `JWT_SECRET` | Секретный ключ JWT |
+| `POSTGRES_PASSWORD` | Пароль PostgreSQL |
+| `WEBDAV_USER` | WebDAV пользователь |
+| `WEBDAV_PASSWORD` | WebDAV пароль |
+
+### Генерация SSH ключа
+
+На вашем локальном компьютере:
+
+```bash
+# Сгенерируйте ключ (без пароля для CI/CD)
+ssh-keygen -t ed25519 -C "github-actions" -f ~/.ssh/nanaxe_deploy
+
+# Добавьте публичный ключ на VPS
+ssh-copy-id -i ~/.ssh/nanaxe_deploy.pub root@YOUR_VPS_IP
+
+# Скопируйте приватный ключ для GitHub
+cat ~/.ssh/nanaxe_deploy
+# Скопируйте вывод в секрет VPS_SSH_KEY
+```
+
+---
+
+## Настройка VPS
+
+### 1. Быстрая настройка (автоматическая)
+
+```bash
+# На VPS выполните:
+curl -fsSL https://raw.githubusercontent.com/YOUR_USERNAME/nanaxe-crm/main/server/scripts/setup-vps.sh | bash
+```
+
+### 2. Ручная настройка
+
+```bash
+# Скопируйте скрипт на VPS
+scp server/scripts/setup-vps.sh root@YOUR_VPS_IP:/tmp/
+
+# Выполните
+ssh root@YOUR_VPS_IP
+chmod +x /tmp/setup-vps.sh
+/tmp/setup-vps.sh
+```
+
+### 3. Что делает скрипт
+
+- ✅ Обновляет систему
+- ✅ Устанавливает Docker и Docker Compose
+- ✅ Настраивает UFW firewall
+- ✅ Устанавливает Fail2Ban
+- ✅ Создаёт директорию деплоя
+- ✅ Настраивает SSL (Let's Encrypt)
+- ✅ Создаёт systemd сервис
+- ✅ Генерирует секреты
+
+---
+
+## Первый деплой
+
+### 1. Локально настройте окружение
+
+```bash
+cd server
+cp .env.example .env
+# Отредактируйте .env
+```
+
+### 2. Запушьте на GitHub
+
+```bash
+git add .
+git commit -m "Add server deployment configuration"
+git push origin main
+```
+
+### 3. Запустите GitHub Actions
+
+Перейдите в **Actions** вкладку на GitHub и запустите workflow вручную или дождитесь автоматического запуска.
+
+### 4. Проверьте деплой
+
+```bash
+# На VPS
+ssh root@YOUR_VPS_IP
+cd /opt/nanaxe-server/server
+docker compose -f docker-compose.prod.yml ps
+docker compose -f docker-compose.prod.yml logs -f
+```
+
+---
+
+## Автоматический деплой
+

+
+### Триггеры деплоя
+
+Автодеплой запускается при:
+- Push в `main` или `master` ветку
+- Merge Pull Request
+- Ручной запуск через GitHub UI
+
+### Проверка статуса
+
+```bash
+# На VPS
+docker compose -f docker-compose.prod.yml ps
+
+# Логи API
+docker compose -f docker-compose.prod.yml logs api -f
+
+# Логи Gitea
+docker compose -f docker-compose.prod.yml logs gitea -f
+```
+
+---
+
+## 🔧 Полезные команды
+
+### Ручной деплой
+
+```bash
+# На VPS
+cd /opt/nanaxe-server/server
+bash scripts/deploy.sh
+```
+
+### Откат (Rollback)
+
+```bash
+# Через GitHub Actions
+# Actions → Deploy Nanaxe Server → Run workflow → Use workflow from: main
+# Выберите "Rollback" (если добавлено) или вручную:
+
+# На VPS
+docker compose -f docker-compose.prod.yml down
+docker compose -f docker-compose.prod.yml up -d
+```
+
+### Обновление
+
+```bash
+# Локально
+ git pull origin main
+# Внесите изменения
+git add . && git commit -m "Update" && git push
+
+# GitHub Actions автоматически задеплоит
+```
+
+### Мониторинг
+
+```bash
+# Статус сервисов
+docker compose -f docker-compose.prod.yml ps
+
+# Использование ресурсов
+docker stats
+
+# Логи в реальном времени
+docker compose -f docker-compose.prod.yml logs -f --tail=100
+```
+
+---
+
+## 🐛 Устранение неполадок
+
+### Проблема: Деплой не запускается
+
+```bash
+# Проверьте GitHub Actions logs
+# Actions → Deploy Nanaxe Server → Последний run
+```
+
+### Проблема: SSH подключение не работает
+
+```bash
+# На VPS проверьте ключ

+# 🔄 Как включить реальный API DeepSeek
+
+## Текущий режим: MOCK ✅
+
+Сейчас приложение работает с **mock данными** (без реальных запросов к API).
+
+Это означает:
+- ✅ Все функции работают без интернета
+- ✅ Не расходуется баланс DeepSeek
+- ⚠️ Ответы не от AI, а заготовленные шаблоны
+
+---
+
+## Когда включить реальный API
+
+### Шаг 1: Проверьте баланс DeepSeek
+
+1. Зайдите на https://platform.deepseek.com/billing
+2. Убедитесь что на счету есть средства (минимум $1-2)
+3. Если баланс пуст - пополните счёт
+
+### Шаг 2: Измените режим в коде
+
+Откройте файл: `lib/core/deepseek_service.dart`
+
+Найдите строку (примерно строка 12):
+```dart
+final bool useMockMode = true;
+```
+
+Измените на:
+```dart
+final bool useMockMode = false;
+```
+
+### Шаг 3: Перезапустите приложение
+
+```bash
+flutter run
+```
+
+---
+
+## Как это работает
+
+### Mock режим (useMockMode = true)
+```
+Запрос → DeepSeek Service → Mock данные → Ответ
+         (без API запросов)
+```
+
+**Плюсы:**
+- Быстро (без сетевых задержек)
+- Бесплатно (не нужен API)
+- Стабильно (всегда работает)
+
+**Минусы:**
+- Ответы не от AI
+- Не адаптированы под контекст
+
+### Реальный API (useMockMode = false)
+```
+Запрос → DeepSeek Service → DeepSeek API → AI ответ
+         (реальный запрос)
+```
+
+**Плюсы:**
+- Умные ответы от AI
+- Адаптация под контекст
+- Качественные описания
+
+**Минусы:**
+- Расходует токены (~$0.001-0.01 за запрос)
+- Нужен интернет
+- Медленнее (1-3 секунды)
+
+---
+
+## Проверка работы API
+
+После включения реального API, запустите тест:
+
+```bash
+dart run test_deepseek_api.dart
+```
+
+Если видите ✅ вместо ❌ - API работает!
+
+---
+
+##Fallback режим
+
+Даже при `useMockMode = false`, если API запрос не прошёл (нет баланса, ошибка сети), 
+сервис автоматически вернётся к mock данным.
+
+В консоли увидите:
+```
+DeepSeek API Error: 402 - Insufficient Balance
+⚠️ Используется mock режим как fallback
+```
+
+---
+
+## Стоимость запросов
+
+Примерные расходы на DeepSeek API:
+
+| Действие | Токенов | Стоимость |
+|----------|---------|-----------|
+| Генерация подзадач | ~500 | $0.0001 |
+| Приоритизация | ~100 | $0.00003 |
+| Описание задачи | ~200 | $0.00006 |
+| Планирование | ~1000 | $0.0003 |
+| Mind-карта | ~1500 | $0.0004 |
+
+**При $2 на счету** можно сделать примерно:
+- 20,000 генераций подзадач
+- 60,000 приоритизаций
+- 5,000 mind-карт
+
+---
+
+## Рекомендации
+
+### Для разработки и тестирования
+Оставьте **mock режим** (`useMockMode = true`)
+- Быстрее цикл разработки
+- Не тратите токены
+
+### Для продакшена
+Включите **реальный API** (`useMockMode = false`)
+- Пользователи получат AI функции
+- Расходы минимальные
+
+---
+
+## Troubleshooting
+
+### Ошибка 402: Insufficient Balance
+```
+1. Проверьте баланс: https://platform.deepseek.com/billing
+2. Пополните счёт
+3. Или верните useMockMode = true
+```
+
+### Ошибка 401: Invalid API Key
+```
+1. Проверьте что ключ в .env начинается с 'sk-'
+2. Нет лишних пробелов
+3. Ключ активен в Dashboard
+```
+
+### Ошибка сети
+```
+1. Проверьте интернет-соединение
+2. DeepSeek может быть недоступен в вашем регионе
+3. Сервис автоматически переключится на mock
+```

+1. [Подготовка VPS](#подготовка-vps)
+2. [Установка Docker](#установка-docker)
+3. [Настройка сервера](#настройка-сервера)
+4. [Запуск](#запуск)
+5. [Настройка домена и SSL](#настройка-домена-и-ssl)
+6. [Подключение Flutter-приложения](#подключение-flutter-приложения)
+
+---
+
+## Подготовка VPS
+
+### 1. Создание LXC контейнера в Proxmox
+
+```bash
+# На хосте Proxmox создайте контейнер
+pct create 100 local:vztmpl/ubuntu-22.04-standard_22.04-1_amd64.tar.zst \
+  --hostname nanaxe-server \
+  --memory 2048 \
+  --cores 2 \
+  --rootfs local-lvm:10 \
+  --net0 name=eth0,bridge=vmbr0,ip=dhcp
+
+# Запустите контейнер
+pct start 100
+
+# Войдите в контейнер
+pct enter 100
+```
+
+### 2. Обновление системы
+
+```bash
+apt update && apt upgrade -y
+apt install -y curl wget git nano htop
+```
+
+---
+
+## Установка Docker
+
+```bash
+# Установка Docker
+curl -fsSL https://get.docker.com -o get-docker.sh
+sh get-docker.sh
+
+# Добавление пользователя в группу docker
+usermod -aG docker $USER
+
+# Установка Docker Compose
+apt install -y docker-compose-plugin
+
+# Проверка
+docker --version
+docker compose version
+```
+
+---
+
+## Настройка сервера
+
+### 1. Клонирование репозитория
+
+```bash
+cd /opt
+git clone <your-repo-url> nanaxe-server
+cd nanaxe-server/server
+```
+
+### 2. Настройка переменных окружения
+
+```bash
+cp .env.example .env
+nano .env
+```
+
+Заполните файл:
+
+```env
+# Domain configuration
+GITEA_DOMAIN=your-domain.com
+
+# Gitea Configuration
+GITEA_TOKEN=your_gitea_api_token_here
+
+# Security (сгенерируйте случайный ключ)
+JWT_SECRET=$(openssl rand -base64 32)
+
+# WebDAV (optional)
+WEBDAV_USER=admin
+WEBDAV_PASSWORD=your_secure_password
+
+# Database (обязательно измените!)
+POSTGRES_PASSWORD=$(openssl rand -base64 24)
+```
+
+### 3. Создание директорий
+
+```bash
+mkdir -p api/logs
+mkdir -p nginx/html
+```
+
+---
+
+## Запуск
+
+### 1. Первый запуск
+
+```bash
+docker compose up -d
+```
+
+### 2. Проверка статуса
+
+```bash
+docker compose ps
+docker compose logs -f
+```
+
+### 3. Инициализация Gitea
+
+Откройте `http://your-server-ip:3000` и выполните первоначальную настройку:
+
+1. Установите базу данных (уже настроена PostgreSQL)
+2. Создайте администратора
+3. Создайте API токен в Settings → Applications
+4. Добавьте токен в `.env` файл
+
+```bash
+# Перезапустите сервисы
+docker compose restart
+```
+
+---
+
+## Настройка домена и SSL
+
+### 1. Настройка DNS
+
+Укажите A-записи:
+- `your-domain.com` → IP сервера
+- `git.your-domain.com` → IP сервера
+- `api.your-domain.com` → IP сервера
+
+### 2. Установка Certbot
+
+```bash
+apt install -y certbot
+
+# Получение сертификатов
+certbot certonly --standalone -d your-domain.com -d git.your-domain.com -d api.your-domain.com
+```
+
+### 3. Настройка Nginx
+
+Отредактируйте `nginx/nginx.conf`:
+
+```nginx

+
+Добавьте volume для SSL сертификатов:
+
+```yaml
+nginx:
+  volumes:
+    - ./nginx/nginx.conf:/etc/nginx/nginx.conf:ro
+    - ./nginx/html:/usr/share/nginx/html:ro
+    - /etc/letsencrypt:/etc/letsencrypt:ro  # Добавьте это
+```
+
+### 5. Перезапуск
+
+```bash
+docker compose down
+docker compose up -d
+```
+
+---
+
+## Подключение Flutter-приложения
+
+### 1. Настройка сервера в приложении
+
+```dart
+import 'package:nanaxe_crm/core/nanaxe_server_service.dart';
+
+final serverService = NanaxeServerService();
+
+// При инициализации
+await serverService.initialize();
+
+// Если не настроен - настройте
+if (!serverService.isConfigured) {
+  await serverService.configure(
+    'https://api.your-domain.com',
+  );
+}
+
+// Проверка соединения
+final isConnected = await serverService.checkConnection();
+```
+
+### 2. Авторизация
+
+```dart
+// Регистрация
+await serverService.register(
+  'user@example.com',
+  'password',
+  'username',
+);
+
+// Или вход
+await serverService.login(
+  'user@example.com',
+  'password',
+);
+```
+
+### 3. Работа с mindmaps
+
+```dart
+// Получение списка
+final mindmaps = await serverService.getMindMaps();
+
+// Создание
+final newMap = await serverService.createMindMap(
+  title: 'My Project',
+  description: 'Project planning',
+  nodes: [
+    {'id': '1', 'title': 'Root', 'level': 0, 'parentId': null},
+    {'id': '2', 'title': 'Task 1', 'level': 1, 'parentId': '1'},
+  ],
+);
+
+// Синхронизация с Gitea
+await serverService.pushToGitea(commitMessage: 'Updated project plan');
+```
+
+---
+
+## 🔧 Обслуживание
+
+### Обновление
+
+```bash
+cd /opt/nanaxe-server/server
+git pull
+docker compose pull
+docker compose up -d
+```
+
+### Бэкап
+
+```bash
+# Бэкап данных
+tar -czf backup-$(date +%Y%m%d).tar.gz /opt/nanaxe-server/server
+
+# Или бэкап volumes
+docker run --rm -v nanaxe-server_mindmap-data:/data -v $(pwd):/backup alpine tar czf /backup/mindmaps-backup.tar.gz -C /data .
+```
+
+### Мониторинг
+
+```bash
+# Логи
+docker compose logs -f
+
+# Статистика
+docker stats
+
+# Дисковое пространство
+df -h
+docker system df
+```

+## 📱 Obsidian Интеграция
+
+### 1. Git Sync плагин
+
+Установите плагин **Obsidian Git** и настройте:
+
+```bash
+# В настройках плагина
+Remote URL: http://your-domain.com:3000/username/mindmaps.git
+```
+
+### 2. Прямой доступ через WebDAV
+
+Установите плагин **Remote Save** и настройте WebDAV:
+
+```
+URL: http://your-domain.com:8081
+Username: admin
+Password: your_secure_password
+```
+
+---
+
+## 🆘 Устранение неполадок
+
+### Проблема: Порты заняты
+
+```bash
+# Проверка занятых портов
+netstat -tlnp | grep -E '3000|8080|80'
+
+# Измените порты в docker-compose.yml
+```
+
+### Проблема: Permission denied
+
+```bash
+# Проверьте права
+ls -la /opt/nanaxe-server/server
+
+# Исправьте
+chown -R $USER:$USER /opt/nanaxe-server/server
+```
+
+### Проблема: Контейнеры не запускаются
+
+```bash
+# Проверьте логи
+docker compose logs
+
+# Пересоберите
+docker compose down
+docker compose build --no-cache
+docker compose up -d
+```
