+# Unlucky Launcher {{VERSION}}
+
+Rust-native **single-file** Minecraft launcher: iced 0.14 + Material 3 Expressive UI, built-in AI agent
+(chat / config edits / crash diagnosis) and an MCP server other agent tools can attach to.
+No WebView, no bundled runtime, no JRE download needed to start the launcher itself.
+
+## Downloads
+
+| Platform | Asset | Notes |
+| --- | --- | --- |
+| Windows 10/11 x64 | `unlucky-launcher-{{VERSION}}-windows-x64.exe` | single exe, double-click to run |
+| Windows 11 ARM64 | `unlucky-launcher-{{VERSION}}-windows-arm64.exe` | single exe, runs natively on ARM64 Windows |
+| Linux x64 (X11/Wayland) | `unlucky-launcher-{{VERSION}}-linux-x64.tar.gz` | single binary inside, no installer |
+| Linux arm64 (X11/Wayland) | `unlucky-launcher-{{VERSION}}-linux-arm64.tar.gz` | single binary inside; needs glibc 2.35+ |
+| macOS 12+ Apple Silicon | `unlucky-launcher-{{VERSION}}-macos-arm64.tar.gz` | single binary inside, no installer |
+| macOS 12+ Intel | `unlucky-launcher-{{VERSION}}-macos-x64.tar.gz` | single binary inside, no installer |
+
+`LICENSE`, `NOTICE` and `README.md` ship in every archive; on Windows they are attached to
+this release next to the `.exe` (a lone exe cannot carry them), so the license terms travel
+with the download on every platform.
+
+Every slot also ships the command line as its own small asset — `ull-{{VERSION}}-<slot>`
+(`.exe` on Windows):
+
+```bash
+chmod +x ull-{{VERSION}}-linux-x64             # Release 资产不带可执行位，先补上
+./ull-{{VERSION}}-linux-x64 instances list     # servers / CI / Termux: no graphics stack needed
+unlucky-launcher instances list                # desktops: the GUI binary answers the same commands
+```
+
+`ull` runs `instances`, `install`, `launch`, `accounts`, `sessions`, `logs`, `diag`, `config`,
+`java` and `agent`, and links no graphics library at all. The GUI binary accepts the same set
+before it ever opens a window, so on a machine with a desktop you do not need `ull`.
+
+## Support matrix
+
+| Platform | Level | Runtime requirements |
+| --- | --- | --- |
+| Windows 10/11 x64 | first class | nothing beyond the OS (UCRT is part of Win10+) |
+| Windows 11 ARM64 | first class (launcher artifact) | nothing extra; launcher runs natively, the game itself runs through the OS x64 emulation layer with an x64 JDK |
+| macOS 12+ (arm64 / x64) | first class | nothing; unsigned build, see Gatekeeper note |
+| Linux x64, X11 | first class | `libxkbcommon`, `fontconfig`, `libGL` (or software renderer), `libxcb` |
+| Linux x64, Wayland | supported | `wayland-client`, `libxkbcommon`, plus the X11 set for XWayland apps |
+| Linux arm64, X11 | first class | glibc 2.35+ (built on `ubuntu-22.04-arm`, same floor as x64), `libxkbcommon`, `fontconfig`, `libGL`, `libxcb` |
+| Linux arm64, Wayland | supported | the above plus `wayland-client` |
+| Windows 8.1/8/7 | unsupported | baseline was raised to Win10 (decision D21) |
+| Android — Termux + X11 | experimental, not promised | CLI only (the `ull` asset, or build from source), GUI unverified; not part of this release matrix |
+
+Both arm64 rows are **formally released slots** (the assets ship in this release and in
+`SHA256SUMS.txt`), not the experimental Termux path: Linux arm64 is built and smoke-tested on a
+native ARM64 runner, Windows ARM64 is cross-built with the same static-CRT gate as x64.
+
+## Install
+
+**Windows** — put the `.exe` anywhere and run it (pick `-windows-arm64.exe` on ARM64 Windows,
+`-windows-x64.exe` everywhere else). Portable data lives next to the exe when a
+`portable.marker` file is present, otherwise under `%APPDATA%`.
+
+**Linux**
+
+```bash
+tar -xzf unlucky-launcher-{{VERSION}}-linux-x64.tar.gz   # use linux-arm64 on aarch64
+cd unlucky-launcher-{{VERSION}}-linux-x64                # ditto
+chmod +x unlucky-launcher && ./unlucky-launcher
+```
+
+**macOS**
+
+```bash
+tar -xzf unlucky-launcher-{{VERSION}}-macos-arm64.tar.gz
+cd unlucky-launcher-{{VERSION}}-macos-arm64
+xattr -d com.apple.quarantine unlucky-launcher   # unsigned build, Gatekeeper quarantine
+chmod +x unlucky-launcher && ./unlucky-launcher
+```
+
+## No GPU? Software renderer
+
+The UI renders through `wgpu` (GPU) and falls back to the `tiny-skia` CPU rasteriser when no usable
+adapter is present. Force the CPU path on any machine with:
+
+```bash
+unlucky-launcher --software-renderer          # the documented switch
+unlucky-launcher --renderer=cpu               # equivalent: pick the CPU renderer explicitly
+```
+
+## Verify the download
+
+```bash
+# Linux / macOS
+sha256sum -c SHA256SUMS.txt --ignore-missing
+# Windows (PowerShell)
+Get-FileHash .\unlucky-launcher-{{VERSION}}-windows-x64.exe -Algorithm SHA256
+```

+
+## Known limitations of this build
+
+- Microsoft (MSA) account login depends on a Mojang app-id whitelist that is still pending;
+  until it is granted, use offline accounts or authlib-injector (the 403 is reported with a
+  readable diagnostic instead of a silent failure).
+- Binaries are not code-signed / notarized yet: Windows SmartScreen and macOS Gatekeeper warn
+  on first launch. Checksums above are the integrity reference for now.
+- macOS ships the bare binary (single-file promise), not a `.app` bundle: no Dock icon or
+  Finder double-click — launch it from a terminal.
+
+## License
+
+Apache-2.0. Third-party notices are in `NOTICE`. Unlucky Launcher is not affiliated with Mojang or
+Microsoft; it does not ship game files.
+
+## UI framework in this build
+
+Every asset in this release is built from the iced UI (`crates/app-iced`, iced 0.14, MIT) — no Slint
+code is linked into it. The earlier Slint UI (`crates/app`) stays in the repository as historical
+source only: excluded from the cargo workspace, not built, not part of any asset here and not part of
+the release matrix. It did ship in the previous `v0.1.0` release; that release's Slint Royalty-Free
+2.0 attribution remains where it was published, and no asset in this build carries that obligation.
+There is deliberately no "Made with Slint" badge on this page: the obligation follows a Slint-linked
+binary, and this release has none.
