//! # Example: Quickstart
//!
//! This example renders a simple "Hello World" message using the ``embedded_graphics_simulator``.
//!
//! To run this example using the ``embedded_graphics_simulator``, you must have the `sdl2` package installed.
//! See [SDL2](https://github.com/Rust-SDL2/rust-sdl2) for installation instructions.
