-*EMQX* — это масштабируемый, высоко доступный, распределённый MQTT брокер с полностью открытым кодом для интернета вещей, межмашинного взаимодействия и мобильных приложений, который поддерживает миллионы одновременных подключений.
+*EMQX* — это самый масштабируемый и популярный высокопроизводительный MQTT брокер с полностью открытым кодом для интернета вещей, межмашинного взаимодействия и мобильных приложений. EMQX может поддерживать более чем 100 миллионов одновременных соединенией на одном кластере с задержкой в 1 миллисекунду, а также принимать и обрабабывать миллионы MQTT сообщений в секунду.
 
-Начиная с релиза 3.0, брокер *EMQX* полностью поддерживает протокол MQTT версии 5.0, и обратно совместим с версиями 3.1 и 3.1.1, а также протоколами MQTT-SN, CoAP, LwM2M, WebSocket и STOMP. Начиная с релиза 3.0, брокер *EMQX* может масштабироваться до более чем 10 миллионов одновременных MQTT соединений на один кластер.
+Мы [протестировали масштабируемость](https://www.emqx.com/en/blog/reaching-100m-mqtt-connections-with-emqx-5-0) EMQX v5.0 и подтвердили что брокер может поддерживать до 100 миллионов одновременных подключений устройств. Это является критически важной вехой для разработчиков IoT. EMQX 5.0 также поставляется с множеством интересных новых функций и значительными улучшениями производительности, включая более мощный [механизм правил](https://www.emqx.com/en/solutions/iot-rule-engine), улучшенное управление безопасностью, расширение базы данных Mria и многое другое для повышения масштабируемости приложений IoT.
 
-- Полный список возможностей доступен по ссылке: [EMQX Release Notes](https://github.com/emqx/emqx/releases).
+За последние несколько лет EMQX приобрел популярность среди IoT-компаний и используется более чем 20 000 пользователей по всему миру из более чем 50 стран, при этом по всему миру поддерживается более 100 миллионов подключений к IoT-устройствам.
-- Более подробная информация доступна на нашем сайте: [EMQX homepage](https://www.emqx.io/).
 
-## Установка
+Для получения дополнительной информации, пожалуйста, посетите [домашнюю страницу EMQX](https://www.emqx.io/).
 
-Брокер *EMQX* кросплатформенный, и поддерживает Linux, Unix, macOS и Windows. Он может работать на серверах с архитектурой x86_64 и устройствах на архитектуре ARM, таких как Raspberry Pi.
+## Начало работы
 
-Более подробная информация о запуске на Windows по ссылке: [Windows.md](./Windows.md)
+#### EMQX Cloud
 
-#### Установка EMQX с помощью Docker-образа

+### Building on Apple silicon (M1, M2)
+
+Homebrew on Apple silicon [changed default location of it's home directory](https://github.com/Homebrew/brew/issues/9177) from `/usr/local` to `/opt/homebrew` and as a result a few things broke in the process.
+
+Concerning EMQX, when you install `unixodbc` package (one of the dependencies) via Homebrew, and build Erlang/OTP  with [kerl](https://github.com/kerl/kerl), kerl will not be able to find `unixodbc`.
+
+Here is how to solve it:
+
+```bash
+brew install unixodbc kerl
+sudo ln -s $(realpath $(brew --prefix unixodbc)) /usr/local/odbc
+export CC="/usr/bin/gcc -I$(brew --prefix unixodbc)/include"
+export LDFLAGS="-L$(brew --prefix unixodbc)/lib"
+kerl build 24.3
+mkdir ~/.kerl/installations
+kerl install 24.3 ~/.kerl/installations/24.3
+. ~/.kerl/installations/24.3/activate
+```
+
+Then you can proceed with `make`.
