+# R4C - Robots for consumers
+
+## Небольшая предыстория.
+Давным-давно, в далёкой-далёкой галактике, была компания производящая различных 
+роботов. 
+
+Каждый робот(**Robot**) имел определенную модель выраженную двух-символьной 
+последовательностью(например R2). Одновременно с этим, модель имела различные 
+версии(например D2). Напоминает популярный телефон различных моделей(11,12,13...) и его версии
+(X,XS,Pro...). Вне компании роботов чаще всего называли по серийному номеру, объединяя модель и версию(например R2-D2).
+
+Также у компании были покупатели(**Customer**) которые периодически заказывали того или иного робота. 
+
+Когда роботов не было в наличии - заказы покупателей(**Order**) попадали в список ожидания.
+
+---
+## Что делает данный код?
+Это заготовка для сервиса, который ведет учет произведенных роботов,а также 
+выполняет некие операции связанные с этим процессом.
+
+Сервис нацелен на удовлетворение потребностей трёх категорий пользователей:
+- Технические специалисты компании. Они будут присылать информацию
+- Менеджмент компании. Они будут запрашивать информацию
+- Клиенты. Им будут отправляться информация
+___
+
+## Как с этим работать?
+- Создать для этого проекта репозиторий на GitHub
+- Открыть данный проект в редакторе/среде разработки которую вы используете
+- Ознакомиться с задачами в файле tasks.md
+- Написать понятный и поддерживаемый код для каждой задачи 
+- Сделать по 1 отдельному PR с решением для каждой задачи
+- Прислать ссылку на своё решение

+# Task 1. От технического специалиста компании.
+Создать API-endpoint, принимающий и обрабатывающий информацию в формате JSON. 
+В результате web-запроса на этот endpoint, в базе данных появляется запись 
+отражающая информацию о произведенном на заводе роботе. 
+
+_**Примечание от старшего технического специалиста**_: 
+Дополнительно предусмотреть валидацию входных данных, на соответствие существующим в системе моделям.
+
+Пример входных данных:
+
+```{"model":"R2","version":"D2","created":"2022-12-31 23:59:59"}```
+
+```{"model":"13","version":"XS","created":"2023-01-01 00:00:00"}```
+
+```{"model":"X5","version":"LT","created":"2023-01-01 00:00:01"}```
+
+
+# Task 2. От директора компании
+**User Story**: Я как директор хочу иметь возможность скачать по прямой ссылке Excel-файл со сводкой по суммарным показателям производства роботов за последнюю неделю. 
+
+_**Примечание от менеджера**_. Файл должен включать в себя несколько страниц, на каждой из которых представлена информация об одной модели, но с детализацией по версии. 
+
+Схематично для случая с моделью "R2":
+
+```
+ __________________________________
+|Модель|Версия|Количество за неделю|
+ __________________________________
+|  R2  |  D2  |       32           |
+ __________________________________
+|  R2  |  A1  |       41           |
+              ...
+              ... 
+              ...
+|  R2  |  С8  |       99           |
+              ...  
+```
+
+# Task 3. От клиента компании.
+**Job story**: Если я оставляю заказ на робота, и его нет в наличии, я готов подождать до момента появления робота. После чего, пожалуйста пришлите мне письмо.
+
+_**Примечание от менеджера**_: Письмо должно быть следующего формата
+```
+Добрый день!
+Недавно вы интересовались нашим роботом модели X, версии Y. 
+Этот робот теперь в наличии. Если вам подходит этот вариант - пожалуйста, свяжитесь с нами
+```
+где Х и Y это соответственно модель и версия робота.
+
+_**Примечание от старшего технического специалиста**_: Постарайтесь не переопределять встроенные методы модели. Также стремитесь не смешивать контексты обработки данных и бизнес-логику. Рекомендуется использовать механизм сигналов предусмотренный в фреймворке.
