+## Das OS
+### _A light, friendly Void Linux–based desktop with Xfce and a Ukrainian touch_
+
+[![Void Linux](https://img.shields.io/badge/Void_Linux-x86__64_glibc-green)](https://voidlinux.org) [![Xfce](https://img.shields.io/badge/Xfce-4.20-orange)](https://xfce.org) [![runit](https://img.shields.io/badge/init-runit-blue)](https://docs.voidlinux.org/config/services/) [![Go](https://img.shields.io/badge/Go-1.22+-blue)](https://go.dev) [![Version](https://img.shields.io/badge/version-0.1.0-lightgrey)](#)
+
+🇺🇦 [Українська версія](README_ua.md)
+
+### 💡 Purpose
+Void Linux is fast, simple and independent: runit instead of systemd, and its own xbps package manager. Out of the box, though, it is a bare system, and getting it ready for daily use takes hours of setup. Das OS builds a live ISO that boots straight into a configured Xfce desktop. It has its own look, a Ukrainian interface and keyboard layout, and the usual desktop apps. Everything Das OS adds comes from its own xbps packages, so the setup can be reproduced and updated like any other package.
+
+### 📃 Features
+- [Live ISO](#LiveISO) that boots on UEFI and BIOS straight into the desktop
+- [Das OS look](#Look): light and dark themes, generated window frames, wallpapers and logo
+- [Desktop defaults](#Defaults) for Xfce that don't overwrite stock files
+- [Own package repository](#Repository) built by xbps-src from in-tree templates
+- [Containerised build](#Build) that runs on any Linux host with Docker, and QEMU scripts for testing
+
+### ⭐ Advantages
+- **Void underneath** – a fast runit boot, the xbps package manager and fresh software, with none of the manual setup.
+- **Light** – no systemd, plus Xfce, LightDM and PipeWire, so it runs well on older laptops too.
+- **Nothing hidden** – all customisations ship as ordinary xbps packages, so `xbps-query -f das-settings` shows exactly what changed.
+- **Users keep control** – defaults live in `/etc/xdg/das`, so a user's own settings always take precedence and upgrades never reset them.
+- **Builds anywhere** – the build runs in a Void container, so the host can be Mint, Ubuntu or Fedora.

+
+### 📌 Using
+
+#### Live ISO<a id='LiveISO' />
+**_The live system logs in to the desktop on its own, with no installation needed._**
+- Boots on UEFI (GRUB) and on legacy BIOS (isolinux), both with a Das OS splash screen.
+- The *graphics disabled* entry boots with `nomodeset` for machines whose screen stays black, and the *RAM* entry copies the whole system to memory.
+- User `live`, password `live`, with `sudo` that needs no password. The user is created at boot and exists only in the live session.
+- Ukrainian interface (`uk_UA.UTF-8`) and the Kyiv time zone by default. Keyboard layouts are `us,ua`, switched with Alt+Shift.
+- Includes NetworkManager, Bluetooth, PipeWire sound and Firefox with the Ukrainian language pack. Services run under runit: `dbus`, `elogind`, `polkitd`, `NetworkManager`, `bluetoothd`, `lightdm`.
+- Includes guest tools for QEMU/SPICE and VirtualBox.
+
+#### Das OS look<a id='Look' />
+**_A modern minimal style with a blue and yellow eight-petal star from Ukrainian embroidery._**
+- The GTK themes `DasOS` and `DasOS-Dark` build on adw-gtk3 and add the Das OS accent colours. They also style the Xfce panel, which adw-gtk3 leaves black.
+- The xfwm4 window frames (rounded corners, round buttons, a red close button on hover) are generated as PNG files by `xfwm4gen` (Go) from a single palette.
+- Light and dark wallpapers show the star over a rushnyk-style embroidered ribbon. The same star is the Das OS logo and the menu button.
+- Fonts are Inter for the interface and JetBrains Mono in the terminal. Icons are Papirus and the cursor theme is Adwaita.
+
+#### Desktop defaults<a id='Defaults' />
+**_The das-settings package configures Xfce without touching files owned by other packages._**
+- `/etc/profile.d/das-xdg.sh` puts `/etc/xdg/das` before `/etc/xdg`, and xfconf reads the Das OS defaults from there.
+- One bottom panel holds the Whisker menu, window buttons, tray, keyboard layout, volume, notifications, clock and a show-desktop button.
+- At the first login, `das-session-init` sets the wallpaper on every connected monitor, because Xfce stores wallpapers per monitor name.
+- LightDM uses the GTK greeter with the Das OS theme and wallpaper.
+
+#### Own package repository<a id='Repository' />
+**_Every Das OS file is installed and updated by xbps._**
+- `srcpkgs/das-theme` contains the themes, xfwm4 frames, wallpapers and logo.
+- `srcpkgs/das-settings` contains the Xfce, LightDM and session defaults.
+- `srcpkgs/adw-gtk3` and `srcpkgs/font-jetbrains-mono` package upstream releases that Void does not have.
+- `make packages` lays the templates over a shallow clone of void-packages and builds them with `xbps-src` into `out/hostdir/binpkgs`. The ISO build installs them from there.
+
+#### Containerised build<a id='Build' />
+**_The whole build runs in a Docker container, so only Docker and QEMU are needed on the host._**
+1. `make packages` builds the local xbps repository.
+2. `make iso` builds the packages and then the ISO with `void-mklive`, using the profile in `live/` (package list, services, root file system overlay).
+3. `make qemu` boots the newest ISO with UEFI. `make qemu-bios` uses legacy BIOS, and `make qemu-disk` also attaches a 20 GB virtual disk.
+
+### 🚀 Building the application
+Requirements: Linux with Docker (the user must be in the `docker` group), QEMU and OVMF for testing, and Go 1.22+ for `make test`. About 10 GB of free disk space.
+```shell
+make iso                 # build packages and the live ISO (the first run downloads ~2 GB)
+make qemu                # boot it in QEMU with UEFI
+make test                # run Go tests
+make clean               # remove build output, keep the download cache
+```
+The ISO appears in `out/iso/dasos-<version>-x86_64.iso`. Write it to a USB stick with `dd` or Ventoy.
+
+**Note:** Das OS is an early version (0.1.0) and the live ISO cannot install itself yet. The Calamares installer, Btrfs snapshots with rollback, the Go utilities `das-welcome` and `das-update`, the developer profile and signed repository hosting are planned for upcoming stages. Das OS is based on Void Linux but is not affiliated with it.

+## Das OS
+### _Легкий і дружній десктоп на базі Void Linux з Xfce та українським колоритом_
+
+[![Void Linux](https://img.shields.io/badge/Void_Linux-x86__64_glibc-green)](https://voidlinux.org) [![Xfce](https://img.shields.io/badge/Xfce-4.20-orange)](https://xfce.org) [![runit](https://img.shields.io/badge/init-runit-blue)](https://docs.voidlinux.org/config/services/) [![Go](https://img.shields.io/badge/Go-1.22+-blue)](https://go.dev) [![Version](https://img.shields.io/badge/version-0.1.0-lightgrey)](#)
+
+🇬🇧 [English version](README.md)
+
+### 💡 Призначення
+Void Linux швидкий, простий і незалежний: runit замість systemd і власний менеджер пакетів xbps. Проте з коробки це гола система, і щоб довести її до щоденного використання, треба кілька годин налаштовувати. Das OS збирає live-образ ISO, який одразу завантажується в налаштований десктоп Xfce. У ньому власне оформлення, український інтерфейс і розкладка та звичні програми. Усе, що додає Das OS, постачається власними xbps-пакетами, тож налаштування можна відтворити й оновлювати, як будь-який інший пакет.
+
+### 📃 Можливості
+- [Live ISO](#LiveISO), що завантажується з UEFI і BIOS одразу в робочий стіл
+- [Оформлення Das OS](#Look): світла й темна теми, згенеровані рамки вікон, шпалери та логотип
+- [Налаштування за замовчуванням](#Defaults) для Xfce, які не перезаписують стандартні файли
+- [Власний репозиторій пакетів](#Repository), який xbps-src збирає з шаблонів у дереві проєкту
+- [Збирання в контейнері](#Build), яке працює на будь-якому Linux із Docker, і скрипти QEMU для тестування
+
+### ⭐ Переваги
+- **Void усередині** – швидке завантаження з runit, менеджер пакетів xbps і свіжі програми без ручного налаштування.
+- **Легкість** – без systemd, а з Xfce, LightDM і PipeWire система добре працює навіть на старих ноутбуках.
+- **Нічого прихованого** – усі зміни постачаються звичайними xbps-пакетами, і `xbps-query -f das-settings` показує, що саме змінено.
+- **Контроль у користувача** – налаштування за замовчуванням лежать у `/etc/xdg/das`, тож власні налаштування користувача завжди мають пріоритет і не скидаються після оновлень.
+- **Збирається будь-де** – збирання відбувається в контейнері Void, тому хостом може бути Mint, Ubuntu чи Fedora.

+
+### 📌 Використання
+
+#### Live ISO<a id='LiveISO' />
+**_Live-система сама входить у робочий стіл, без встановлення._**
+- Завантажується з UEFI (GRUB) і зі старого BIOS (isolinux), в обох випадках із заставкою Das OS.
+- Пункт *graphics disabled* завантажує систему з параметром `nomodeset`, якщо на якомусь комп'ютері екран лишається чорним, а пункт *RAM* копіює всю систему в пам'ять.
+- Користувач `live`, пароль `live`, `sudo` працює без пароля. Користувач створюється під час завантаження й існує лише в live-сесії.
+- Український інтерфейс (`uk_UA.UTF-8`) і часовий пояс Києва за замовчуванням. Розкладки `us,ua`, перемикання Alt+Shift.
+- Є NetworkManager, Bluetooth, звук PipeWire і Firefox з українською мовою. Сервіси працюють під runit: `dbus`, `elogind`, `polkitd`, `NetworkManager`, `bluetoothd`, `lightdm`.
+- Є гостьові інструменти для QEMU/SPICE та VirtualBox.
+
+#### Оформлення Das OS<a id='Look' />
+**_Сучасний мінімалізм із синьо-жовтою восьмипелюстковою зіркою з української вишивки._**
+- GTK-теми `DasOS` і `DasOS-Dark` побудовані на adw-gtk3 і додають акцентні кольори Das OS. Вони також оформлюють панель Xfce, яку adw-gtk3 лишає чорною.
+- Рамки вікон xfwm4 (заокруглені кути, круглі кнопки, червона кнопка закриття при наведенні) генерує у PNG утиліта `xfwm4gen` (Go) з однієї палітри.
+- Світлі й темні шпалери зображують зірку над смугою орнаменту в стилі рушника. Та сама зірка є логотипом Das OS і кнопкою меню.
+- Шрифти: Inter для інтерфейсу і JetBrains Mono в терміналі. Іконки Papirus, тема курсора Adwaita.
+
+#### Налаштування за замовчуванням<a id='Defaults' />
+**_Пакет das-settings налаштовує Xfce, не чіпаючи файлів інших пакетів._**
+- `/etc/profile.d/das-xdg.sh` ставить `/etc/xdg/das` перед `/etc/xdg`, і xfconf бере звідти налаштування Das OS.
+- Одна нижня панель містить меню Whisker, кнопки вікон, трей, розкладку клавіатури, гучність, сповіщення, годинник і кнопку «показати стільницю».
+- При першому вході `das-session-init` встановлює шпалери на кожному підключеному моніторі, бо Xfce зберігає шпалери за назвою монітора.
+- LightDM використовує GTK-вітальню з темою і шпалерами Das OS.
+
+#### Власний репозиторій пакетів<a id='Repository' />
+**_Кожен файл Das OS встановлює й оновлює xbps._**
+- `srcpkgs/das-theme` містить теми, рамки xfwm4, шпалери й логотип.
+- `srcpkgs/das-settings` містить налаштування Xfce, LightDM і сесії.
+- `srcpkgs/adw-gtk3` і `srcpkgs/font-jetbrains-mono` пакують релізи з GitHub, яких немає у Void.
+- `make packages` накладає шаблони на неглибокий клон void-packages і збирає їх через `xbps-src` в `out/hostdir/binpkgs`. Збирання ISO встановлює їх звідти.
+
+#### Збирання в контейнері<a id='Build' />
+**_Усе збирання відбувається в Docker-контейнері, тож на хості потрібні лише Docker і QEMU._**
+1. `make packages` збирає локальний xbps-репозиторій.
+2. `make iso` збирає пакети, а потім ISO через `void-mklive` за профілем у `live/` (список пакетів, сервіси, оверлей кореневої файлової системи).
+3. `make qemu` завантажує найновіший ISO з UEFI. `make qemu-bios` використовує старий BIOS, а `make qemu-disk` ще й підключає віртуальний диск на 20 ГБ.
+
+### 🚀 Збирання застосунку
+Вимоги: Linux із Docker (користувач має бути в групі `docker`), QEMU та OVMF для тестування, Go 1.22+ для `make test`. Приблизно 10 ГБ вільного місця.
+```shell
+make iso                 # зібрати пакети й live-ISO (перший запуск завантажує ~2 ГБ)
+make qemu                # запустити його в QEMU з UEFI
+make test                # запустити Go-тести
+make clean               # видалити результати збирання, зберегти кеш завантажень
+```
+ISO з'являється в `out/iso/dasos-<версія>-x86_64.iso`. Записати його на флешку можна через `dd` або Ventoy.
+
+**Примітка:** Das OS — рання версія (0.1.0), і live-ISO поки не вміє встановлюватися на диск. Інсталятор Calamares, знімки Btrfs із відкатом, Go-утиліти `das-welcome` і `das-update`, профіль розробника та підписаний репозиторій на хостингу заплановані на наступні етапи. Das OS базується на Void Linux, але не пов'язана з ним офіційно.
