This is a placeholder crate for niri, a scrollable-tiling Wayland compositor. The crate is published to avoid malicious name squatting.
You cannot properly install niri with cargo install. A compositor needs things like desktop/session files, portal configuration, and service units, that cargo install cannot provide.
Please install niri from your distribution packages: https://niri-wm.github.io/niri/Getting-Started.html
