umbra-tui is both an executable binary that can be run, and a library that can be used in Rust programs.
Installing the document executable
Assuming you have Rust/Cargo installed, run this command in a terminal:
cargo install umbra-tui
It will make the document command available in your PATH if you've allowed the PATH to be modified when installing Rust. cargo uninstall umbra-tui uninstalls.
Adding umbra library as a dependency
Run this command in a terminal, in your project's directory:
cargo add umbra-tui
To add it manually, edit your project's Cargo.toml file and add to the [dependencies] section:
umbra-tui = "0.1.0"
The umbra library will be automatically available globally.
Read the umbra library documentation.
