-# go-musthave-group-diploma-tpl
+# Accumulative Loyalty System
 
-Шаблон репозитория для группового дипломного проекта курса "Go-разработчик"
+## Overview
 
-# Начало работы
+The project is divided into two parts: an accrual system and a core system.
 
-1. Склонируйте репозиторий в любую подходящую директорию на вашем компьютере
-2. В корне репозитория выполните команду `go mod init <name>` (где `<name>` — адрес вашего репозитория на GitHub без
-   префикса `https://`) для создания модуля
+The accrual system provides an opportunity to register information about the reward for the order and to register the order for the calculation of bonus points.
 
-# Обновление шаблона
+The core system allows the user to register and start registering their completed orders, then the core system accesses the accrual system to obtain the number of points to be credited to the user, as well as the user can write off the accumulated points for future orders.
