//! # [Ratatui] Minimal example
//!
//! This is a bare minimum example. There are many approaches to running an application loop, so
//! this is not meant to be prescriptive. See the [examples] folder for more complete examples.
//! In particular, the [hello-world] example is a good starting point.
//!

//!
//! The latest version of this example is available in the [examples] folder in the repository.
//!
//! Please note that the examples are designed to be run against the `main` branch of the Github
//! repository. This means that you may not be able to compile with the latest release version on
//! crates.io, or the one that you have installed locally.
//!
//! See the [examples readme] for more information on finding examples that match the version of the
//! library you are using.
