 #**SkillBox LMS**
 
-Подробные шаги для проверки работоспособности CI
+Нужно выполнить миграции и запустить скрипт update_db.py без параметров в модуле courses (скрипт на всякий случай пока не удалять)
 
-1) Проверяем доступ к репозиторию кода https://gitlab.com/skillbox/go.skillbox.ru
-2) Клонируем проект
-3) Вносим изменения в код
-4) Комитим изменения в новый branch (ОБЯЗАТЕЛЬНО в отдельный Branch)
-4.1) Пушим изменения
-5) Ждем выполнения создания тестового сайта https://gitlab.com/skillbox/go.skillbox.ru/pipelines
-6) Сайт будет доступен по адресу <branch_name>.lms.test.spicycms.com
+Фактически в структуре данных изменилось только то, что появилась новая табличка NormalMap. Скрипт собирает все treeview курсов и кладёт в эту табличку
 
-**Правила для разработчика**
+Появилась новая зависимость django_rest_framework.
 
-* Разрабока ведется в отдельном брэнче
-* После комита изменений можно проверить свою работу по следующему адресу: .lms.test.spicycms.com
-* После проверки тестового сайта по имени брэнча, брэнч помечается к мерж реквесту
-* Ответсвенный инженер производит код ревью и запускает/отклоняет мерж
-* Если сайт запустился на демо сайте, код в ручом режиме можно обновить на продакшен сервере
+Изменения никак не трогают старый функционал.
 
-**Замечания**
-
-* Мерж реквест лучше производить в ветку develop(чтобы исключить случайного обновления кода на демо сайте)
-* Внимание! Разработчик обязан проверить работоспособность тестового сайта по имени созданного брэнча .lms.test.spicycms.com
-* Если необходимы тестовые данные разработчик их подготавливает дополнительно
-* Если нет возможности добавить тестовые данные в авто режиме, разработчик добавляет инструкцию в README файл по запуску необходимых команд
-(Под тестовыми данными подразумеваются фикстуры)
+Имеет смысл пробежаться по middl
