# One-shot Ubuntu provisioning for the CodeBurn desktop (Tauri) dev environment.
#
# Usage inside a fresh Ubuntu 24.04 LTS Server VM (after `sudo apt install
# ubuntu-desktop-minimal && sudo reboot`, and logging into GNOME):
#
#   curl -fsSL https://raw.githubusercontent.com/AgentSeal/codeburn/feat/tauri-menubar-win-linux/desktop/Scripts/provision-linux.sh | bash
#
# Or if you cloned the repo manually: `bash desktop/Scripts/provision-linux.sh`.
#
# Installs: build toolchain, webkit + appindicator headers, Node 20 LTS, Rust stable,
# the codeburn npm CLI, and this repo. Leaves you one command away from `npm run tauri dev`.
