-# Local DNS Services with Docker
+# Локальная сеть с доменами `.mikan` и HTTPS
 
-This project provides a local development infrastructure with automatic DNS resolution for custom domains (e.g., `.mikan` or `.local`) and valid HTTPS certificates.
+Система для запуска сервисов в Docker с автоматическим HTTPS, локальными доменами (`service.mikan`, `service.local`) и возможностью расширения (Tailscale, публичные домены).
 
-## Features
+## Требования
 
-- Automatic DNS resolution for `*.yourdomain` and `*.yourdomain.local`
-- Valid HTTPS certificates for local domains using `mkcert`
-- Easy service deployment with `VIRTUAL_HOST` environment variables
-- Ready for future expansion: public domains, Let's Encrypt, Tailscale
-- Single-command service creation
+- Docker + Docker Compose
+- `mkcert` — [инструкция по установке](https://github.com/FiloSottile/mkcert#installation)
+- `bash`, `coreutils`
 
-## Requirements
+## Быстрый старт
 
-- Docker and Docker Compose
-- `mkcert` installed on the host system
-
-## Quick Start
-
-1. Clone this repository and enter the directory:
+1. **Клонируй репозиторий**
    ```bash
-   git clone <repository-url> local-dns
-   cd local-dns
+   git clone ... && cd local-dns
    ```
 
-2. Initialize the project:
+2. **Настрой домен (опционально)**
    ```bash
-   ./scripts/00-init.sh
+   echo "LOCAL_DOMAIN=mikan" > .env
    ```
-   This creates a `.env` file from `.env.example` and sets up the directory structure.
+   Замени `mikan` на желаемый суффикс (например, `home`).
 
-3. Generate TLS certificates:
+3. **Инициализируй CA и базовый сертификат**
    ```bash
-   ./scripts/01-generate-cert.sh
+   ./scripts/01-init-ca.sh
    ```
-   This creates trusted certificates for your local domain.
+   - Создаст доверенный корневой сертификат (`ca/rootCA.pem`)
+   - Сгенерирует `default.crt` для nginx-proxy
 
-4. Start the core infrastructure:
+4. **Установи корневой сертификат в систему**  
+   Импортируй файл `ca/rootCA.pem` в хранилище **доверенных корневых центров сертификации**:
+   - **Linux**:  
+     ```bash
+     sudo cp ca/rootCA.pem /usr/local/share/ca-certificates/mkcert-local.crt
+     sudo update-ca-certificates
+     ```
+   - **Windows/macOS**: двойной клик по файлу → «Доверять всегда» (macOS) или импорт в «Доверенные корневые центры» (Windows)
+
+5. **Запусти инфраструктуру**
    ```bash
    docker compose up -d
    ```
 
-5. Add your first service (example: Gitea on port 3000):
+6. **Добавь сервис**
    ```bash
-   ./scripts/add-service.sh gitea 3000
+   ./scripts/add-service.sh gitea
    ```
-   Then edit `services/gitea/docker-compose.yml` to set the correct image and volumes.
+   Сервис будет доступен по:
+   - `https://gitea.mikan`
+   - `https://gitea.local`
 
-6. Start the new service:
-   ```bash
-   docker compose -f docker-compose.yml -f services/gitea/docker-compose.yml up -d
+   \+ может пригодиться:
+
+    ```bash
+    Add-Content -Path "C:\Windows\System32\drivers\etc\hosts" -Value "10.0.0.3 youtrack.mikan"
+    ```
+
+7. **Настрой сервис в Docker Compose**  
+   Убедись, что в `docker-compose.yml` сервиса указано:
+   ```yaml
+   services:
+     gitea:
+       environment:
+         - VIRTUAL_HOST=gitea.mikan,gitea.local
+         - VIRTUAL_PORT=3000  # порт внутри контейнера
+       networks:
+         - devnet
+       dns: 10.0.0.2  # обязательно для резолвинга доменов из контейнеров
    ```
 
-7. Visit `https://gitea.yourdomain` in your browser (replace `yourdomain` with your configured domain).
+## Важные замечания
 
-## Configuration
+### DNS из контейнеров
+Контейнеры **не могут** резолвить `*.mikan` без явного указания DNS:
+```yaml
+dns: 10.0.0.2  # IP dnsmasq
+```
+Добавляй эту строку во все сервисы, которым нужен доступ к другим по домену.
 
-Edit the `.env` file to customize your setup:
+### Обновление сертификатов
+При добавлении сервиса через `add-service.sh`:
+- Автоматически обновляется `domains.txt`
+- Генерируется новый `default.crt`
+- Перезагружается `nginx-proxy`
 
-- `LOCAL_DOMAIN`: Your local domain suffix (default: `mikan`)
-- `PUBLIC_DOMAIN`: Optional public domain for Let's Encrypt certificates
-- `LETSENCRYPT_EMAIL`: Email for Let's Encrypt notifications
-- Network settings (`NGINX_IP`, `DNSMASQ_IP`, etc.)
+### Пути
+- Сертификаты: `nginx/certs/default.crt`
+- Домены: `domains.txt`
+- Корневой CA: `ca/rootCA.pem`
 
-After changing `.env`, re-run the initialization and certificate scripts.
+## Расширение
 
-## DNS Setup
-
-### Linux/macOS
-
-Use the included `dnsmasq` service for automatic DNS resolution:
-
-```bash
-docker compose -f docker-compose.yml -f docker-compose.dnsmasq.yml up -d
+### Tailscale
+Добавь в `docker-compose.yml` сервис `tailscale` и объявляй дополнительные домены:
+```yaml
+environment:
+  - VIRTUAL_HOST=gitea.mikan,gitea.local,gitea.yourname.ts.net
 ```
 
-Then configure your system to use `10.0.0.2` as the primary DNS server.
-
-### Windows (WSL2)
-
-Windows reserves port 53, so `dnsmasq` cannot run on the host. Instead:
-
-1. Work inside WSL2
-2. Manually add entries to the Windows hosts file:
-   ```powershell
-   # Run PowerShell as Administrator
-   Add-Content -Path "C:\Windows\System32\drivers\etc\hosts" -Value "127.0.0.1 gitea.mikan"
-   Add-Content -Path "C:\Windows\System32\drivers\etc\hosts" -Value "127.0.0.1 gitea.mikan.local"
+### Публичный домен
+1. Купи домен (например, `example.com`)
+2. В `.env` добавь:
+   ```env
+   PUBLIC_DOMAIN=example.com
    ```
-
-## Certificate Trust
-
-After running `./scripts/01-generate-cert.sh`, install the root certificate on your devices:
-
-- **Linux**: Depends on distribution (usually via `update-ca-certificates`)
-- **macOS**: 
-  ```bash
-  sudo security add-trusted-cert -d -r trustRoot -k /Library/Keychains/System.keychain ca/rootCA.pem
-  ```
-- **Windows**: 
-  1. Copy `ca/rootCA.pem` to Windows
-  2. Open `certmgr.msc`
-  3. Import into "Trusted Root Certification Authorities"
-
-## Adding Public Domain Support
-
-To enable Let's Encrypt certificates for a public domain:
-
-1. Set in `.env`:
-   ```ini
-   PUBLIC_DOMAIN=yourdomain.com
-   LETSENCRYPT_EMAIL=you@yourdomain.com
+3. В сервисах укажи:
+   ```yaml
+   environment:
+     - VIRTUAL_HOST=gitea.mikan,gitea.local,gitea.example.com
+     - LETSENCRYPT_HOST=gitea.example.com
    ```
+   Сертификат для `example.com` получит `acme-companion`.
 
-2. Re-run initialization:
-   ```bash
-   ./scripts/00-init.sh
-   ./scripts/01-generate-cert.sh
-   ```
+---
 
-3. New services will automatically request Let's Encrypt certificates for the public domain.
-
-## Service Management
-
-- **Add a service**: `./scripts/add-service.sh <name> <port>`
-- **Start all**: `docker compose up -d`
-- **Start with dnsmasq**: `docker compose -f docker-compose.yml -f docker-compose.dnsmasq.yml up -d`
-- **Stop all**: `docker compose down`
-
-All service data is stored in the `services/` directory and persists between restarts.
