+# OpenCut Desktop
+
+Built with [GPUI](https://www.gpui.rs).
+
+> [!WARNING]
+> Very early. Right now this is just a window that opens.
+
+## Running
+
+Rust is pinned in `.prototools` at the repo root (`proto use` installs it).
+
+```sh
+moon run desktop:dev     # cargo run
+moon run desktop:check   # cargo check
+moon run desktop:build   # cargo build --release
+```
+
+The first build compiles GPUI from source and takes a while. The root `Cargo.lock` is committed.
+
+## Platform requirements
+
+- **macOS**: Xcode command line tools (Metal renderer).
+- **Windows**: no extra dependencies (Win32 + DirectWrite).
+- **Linux**: renders via Vulkan (Blade), windows via Wayland or X11 (both enabled by default). System packages (Debian/Ubuntu names): `libvulkan1` + working Vulkan drivers, `libwayland-dev`, `libx11-xcb-dev`, `libxkbcommon-x11-dev`, `libfontconfig-dev`, plus a C toolchain and `cmake`.
