Installing the viewer executable

cargo install bevy_flame
It will make the viewer command available in your PATH if you've allowed the PATH to be modified when installing Rust. cargo uninstall bevy_flame uninstalls.
Adding bevy_flame library as a dependency
Run this command in a terminal, in your project's directory:
cargo add bevy_flame
To add it manually, edit your project's Cargo.toml file and add to the [dependencies] section:

The bevy_flame library will be automatically available globally.
