 # ClashDeckGenerator2
 
-🌸 Welcome to your Hanami app!
+Приложение на Hanami 2.3 (Ruby 3.4, SQLite).
 
-## Getting started
+## Запуск на Windows (через winget)
 
-- Set up the project with `bin/setup`
-- Run the server with `bin/dev`
-- View the app at [http://localhost:2300](http://localhost:2300)
-- Run the tests with `bundle exec rake`
+### 1) Установить зависимости
 
-## Useful links
+```bat
+winget install -e --id RubyInstallerTeam.RubyWithDevKit.3.4
+winget install -e --id SQLite.SQLite
+winget install -e --id Git.Git
+```
+
+После установки открой новый терминал (чтобы обновился `PATH`).
+
+### 2) Установить Ruby-зависимости проекта
+
+```bat
+bundle install
+```
+
+### 3) Подготовить БД
+
+```bat
+bundle exec hanami db prepare
+```
+
+Команда создаст/обновит:
+- [`db/db.sqlite3`](db/db.sqlite3)
+- [`db/db_test.sqlite3`](db/db_test.sqlite3)
+
+### 4) Запуск приложения
+
+```bat
+bundle exec puma -C config/puma.rb config.ru
+```
+
+Открыть: [http://localhost:2300](http://localhost:2300)
+
+## Важно про SQLite для Hanami
+
+Для корректной работы нужны **две части**:
+
+1. Ruby-модуль [`gem "sqlite3"`](Gemfile:17) — используется приложением и адаптером БД.
+   Устанавливается через [`bundle install`](README.md:27).
+2. CLI-утилита `sqlite3` (отдельный бинарник) — нужна командам Hanami, например [`hanami db prepare`](README.md:33).
+   Ставится через [`winget install -e --id SQLite.SQLite`](README.md:13).
+
+Если `bundle` или `hanami` не находятся в `cmd`, проверь Ruby в `PATH` или временно добавь:
+
+```bat
+set "PATH=C:\Ruby34-x64\bin;%PATH%"
+```
+
