 # Вещи, которые вам нужно знать перед установкой
 
-- Это альфа версия, которая находится в активной разработке. Из версии в версию что-то может меняться.
-- Основной функционал работает, но побочные штуки сейчас могут сбоить.
-- При обновлении **обязательно** сбрасывайте кэш LuCI.
+- Это бета-версия, которая находится в активной разработке. Из версии в версию что-то может меняться.
+- При возникновении проблем, нужен технически грамотный фидбэк в чат.
+- При обновлении **обязательно** [сбрасывайте кэш LuCI](https://podkop.net/docs/clearbrowsercache/).
 - Также при обновлении всегда заходите в конфигурацию и проверяйте свои настройки. Конфигурация может измениться.
-- Необходимо минимум 15МБ свободного места на роутере. Роутерами с флешками на 16МБ сразу мимо.
+- Необходимо минимум 15МБ свободного места на роутере. Роутеры с флешками на 16МБ сразу мимо.
 - При старте программы редактируется конфиг Dnsmasq.
 - Podkop редактирует конфиг sing-box. Обязательно сохраните ваш конфиг sing-box перед установкой, если он вам нужен.
-- Информация здесь может быть устаревшей. Все изменения фиксируются в телеграм-чате https://t.me/itdogchat - топик **Podkop**.
-- Если у вас не что-то не работает, то следуюет сходить в телеграм чат, прочитать закрепы и выполнить что там написано..
-- Если у вас установлен Getdomains, его следует удалить.

 Основные задачи в issues.
 
-Низкий приоритет
-- [ ] Галочка, которая режет доступ к doh серверам
-- [ ] IPv6. Только после наполнения Wiki
+## Рефактор
+- [ ] Очевидные повторения в `/usr/bin/podkop` загнать в переменые
+- [ ] Возможно поменять структуру
 
-Рефактор
-- [ ] Handle для sing-box
-- [ ] Handle для dnsmasq
+## Списки
+- [ ] Speedtest
+- [x] Google AI
+- [x] Google PlayMarket. Здесь уточнить, что точно не работает через корректную настройку FakeIP, а не dnsmasq+nft.
+- [x] Hetzner ASN (AS24940)
+- [x] OVH ASN (AS16276)
+
+## Будущее
+- [ ] После наполнения вики про туннели, убрать всё что связано с их установкой из скрипта. Только с AWG что-то решить, лучше чтоб был скрипт в сторонем репозитории. 
+- [ ] Подписка. Здесь нужна реализация, чтоб для каждой секции помимо ручного выбора, был выбор фильтрации по тегу. Например, для main выбираем ключевые слова NL, DE, FI. А для extra секции фильтруем по RU. И создаётся outbound c urltest в которых перечислены outbound из фильтров.
+- [ ] Опция, когда все запросы (с роутера в первую очередь), а не только br-lan идут в прокси. С этим связана #95. Требуется много переделать для nftables.
+- [ ] Весь трафик в Proxy\VPN. Вопрос, что делать с экстрасекциями в этом случае. FakeIP здесь скорее не нужен, а значит только main секция остаётся. Всё что касается fakeip проверок, придётся выключать в этом режиме.
+- [ ] Поддержка Source format. Нужна расшифровка в json и если присуствуют подсети, заносить их в custom subnet nftset.
+- [ ] Переделывание функции формирования кастомных списков в JSON. Обрабатывать сразу скопом, а не по одному.
+- [ ] При успешном запуске переходит в фоновый режим и следит за состоянием sing-box. Если вдруг идёт exit 1, выполняется dnsmasq restore и снова следит за состоянием. Вопрос в том, как это искусcтвенно провернуть. Попробовать положить прокси и посмотреть, останется ли работать DNS в этом случае. И здесь, вероятно, можно обойтись триггером в init.d.
