yeli is both an executable binary that can be run, and a library that can be used in Rust programs.
Installing the command-line executable
Assuming you have Rust/Cargo installed, run this command in a terminal:
cargo install yeli
It will make the yeli command available in your PATH if you've allowed the PATH to be modified when installing Rust. cargo uninstall yeli uninstalls.
Adding yeli library as a dependency
Run this command in a terminal, in your project's directory:
cargo add yeli
To add it manually, edit your project's Cargo.toml file and add to the [dependencies] section:
yeli = "0.4.0"
The yeli library will be automatically available globally.
Read the yeli library documentation.
