+# Наш сайт и полная версия
 
-### Серверы
-- **Мультисерверность** — добавление сервера прямо в админке.
-- **Проверка на доступность** — бот следит за серверами и их откликом.
-- **Балансировка** — бот выдает подписку на наименее загруженный сервер.
-- **Сихронизация** — перемещайте клиентов на другие сервера бесшовно.
-
-### Удобная админ-панель
-- **Поиск клиента** — по айди, нику или ключу.
-- **Управление подпиской клиента** — перевыпуск, изменение баланса и остальное.
-- **Управление ботом** — перезагрузка, списки банов, смена домена.
-- *А также рассылки, создание купонов, просмотр детальной статистики и многое другое*

-### Кастомизация
-- **Пробник** — Сами решаете будет или нет. Количество дней пробника также кастомизируется.
-- **Реферальная программа** — процент с каждого пополнения или фиксированная сумма.
-- **Все меню** — меняйте все меню как вам захочется, описания и тексты.
-- **Кешбэк** — начисляйте кэшбек за пополнения, если хотите.
-- **Настройки** — капча, подписка на канал, купоны и прочее.
-- **Автоматика** — удалять ли ключи после продления, продлевать ли их и остальное.
