 1. Скачайте последний [tar.gz релиз](https://github.com/bol-van/zapret/releases) в /tmp, распакуйте его, затем удалите архив.
+   Для openwrt и прошивок используйте вариант `openwrt-embedded`.
+   Для экономия места в /tmp можно качать через curl в stdout и сразу распаковывать.

 2. Убедитесь, что у вас отключены все средства обхода блокировок, в том числе и
   сам zapret. Гарантированно уберет zapret скрипт `uninstall_easy.sh`.
