-Каждая новая ветка для дз должна делаться с master
+[Update ](https://ibb.co/7QqwG24)
 
-После того как вы закончили выполнять домашнее задание в своей ветке, необходимо сделать пулл-реквест (PR). Потом добавить ментора для ревью кода. Только после того как ментор заапрувит PR, вы можете выполнить мердж ветки с домашним заданием в мастер.
+[Update status](https://ibb.co/1zTF2SJ)
 
-Внимательно читайте комментарии ментора. Исправьте замечания и сделайте коммит в ветке с домашним заданием. Изменения подтянуться в PR автоматически после того как вы отправите коммит с исправлениями на github
-После исправления снова добавьте ментора на ревью кода.

-- `npm start` — старт сервера в режиме production
-- `npm run start:dev` — старт сервера в режиме разработки (development)
-- `npm run lint` — запустить выполнение проверки кода с eslint, необходимо выполнять перед каждым PR и исправлять все ошибки линтера
-- `npm lint:fix` — та же проверка линтера, но с автоматическими исправлениями простых ошибок
