+# Форматирование кода перед merge
+
+## Быстрый способ - одна команда:
+
+```bash
+mix format
+git add .
+git commit -m "chore: auto-format code with mix format"
+git push
+```
+
+## Если у вас Docker:
+
+```bash
+docker-compose run app mix format
+git add .
+git commit -m "chore: auto-format code with mix format"
+git push
+```
+
+## Или через make (если есть в Makefile):
+
+```bash
+make format
+git add .
+git commit -m "chore: auto-format code with mix format"
+git push
+```
+
+## После форматирования:
+
+Все файлы будут автоматически приведены к стандарту Elixir formatter.
+Затем можно будет делать merge в master без проблем с CI.
+
+## Файлы, которые нужно отформатировать:
+
+Список файлов был предоставлен в сообщении об ошибке CI.
+`mix format` автоматически обработает их все.
