 ## Как скачать и запустить
 
-**Скачать лаунчер (выбери один):**
-- **Онлайн-установщик (рекомендуется)** — `ZernMC-Online-Setup.exe` (~5.7М, Go, без Java): скачай → выбери папку установки (по умолчанию `C:\ZernMC`) → [x] Создать ярлык ZernMC Launcher на рабочем столе → Установить. Первый запуск докачает JRE 47М + файлы лаунчера 50М. Данные сборок `~/.zernmc` остаются в профиле пользователя. Деинсталляция — `C:\ZernMC\uninstall.exe` или удаление папки.
-- **Оффлайн ZIP** — `ZernMC-win-<версия>.zip` (98М, с JRE): скачай → выбери папку куда распаковать (диалог в `ZernMC-Offline-Setup.exe` или вручную) → [x] Ярлык → готово. Для air-gapped.

 **Решение:**
 1. Запустите версию и посмотрите в логах, какой `.json` файл он пытается загрузить.
 2. Скопируйте правильный файл из `assets/indexes/` и переименуйте его в нужное имя.
