-# Application
+# nginx
+
+## Зависимости
+
+Для работы понадобится установленный `nginx`. 
+* **Ubuntu/Debian:** `sudo apt install nginx`
+* **macOS:** `brew install nginx`
+
+> **Важно:** Убедитесь, что системный сервис nginx (если он запустился после установки) остановлен, чтобы он не занимал 80-й порт:  
+> `sudo lsof -i :80` (чтобы узнать занимает или нет)
+> `sudo systemctl stop nginx` (Linux) или `brew services stop nginx` (macOS).
+
+## Как запустить локально
+
+1. Перейдите в папку с конфигурацией:
+   ```bash
+   cd infra/nginx
+2. Запустите Nginx в привязанном к терминалу режиме (чтобы видеть ошибки и легко останавливать через Ctrl+C):
+    ```bash
+    sudo nginx -p . -c nginx.conf -g "daemon off;"
+    Сервер будет доступен по адресу http://localhost
+3. Для проверки синтаксиса локально:
+    ```bash
+    sudo nginx -t -p . -c nginx.conf
+    ```
+    Вы должны увидеть:
+    ```bash
+    nginx: the configuration file ./nginx.conf syntax is ok
+    nginx: configuration file ./nginx.conf test is successful
+
+4. Если вы запустили его в фоновом режиме (без daemon off;), остановить его можно командой из папки infra/nginx:
+    ```bash
+    sudo nginx -p . -c nginx.conf -s stop
