+![Python version](https://img.shields.io/badge/python-3.8-blue.svg)
+[![Codacy Badge](https://app.codacy.com/project/badge/Grade/c4e370d74a8a4575b79afa8b9b74d130)](https://app.codacy.com/gh/shizand/statapp/dashboard?utm_source=gh&utm_medium=referral&utm_content=&utm_campaign=Badge_grade)
+![License info](https://img.shields.io/github/license/shizand/statapp)
+
+Автоматизированное программное средство по статистическому анализу и регрессионному моделированию. Является идейным продолжателем программы STAT.exe (Produced by Reutov V.N., Donetsk University, 1990)
+
+Разработано двумя студентами ФГБОУ ВО «ДонНТУ» для своего университета.
+
+## Поддерживаемые ОС и архитектуры
+
+В теории, должно работать на любой архитектуре и ОС где запускается Python 3.8 и есть Qt 5.
+
+Работоспособность проверена на x64:
+
+* на Windows 7, 10;
+* на ALT Linux 10.2.
+
+## Установка
+
+Существует два варианта statapp и statapp-onefile. Различия в том, что onefile версия поставляется одним единственным бинарным файлом. На Windows системах с включенным антивирусом это может вызывать [некоторые проблемы](https://qna.habr.com/q/988553).
+
+### Готовые двоичные файлы
+
+[Скачайте архив](https://github.com/shizand/statapp/releases) под вашу платформу и распакуйте в любом месте.
+
+### Сборка из исходников
+
+В этом проекте используется [poetry](https://python-poetry.org/).
+
+```bash
+poetry install
+pyinstaller statapp.spec # или pyinstaller statapp.spec -- --one-file
+```
+
+## Использование
