//!
//! Bevy is an open-source modular game engine built in Rust, with a focus on developer productivity and performance.
//!
//! Check out the [Bevy website](https://bevyengine.org) for more information, read the
//! [Bevy Book](https://bevyengine.org/learn/book/introduction) for a step-by-step guide, and [engage with our
//! community](https://bevyengine.org/community/) if you have any questions or ideas!
//!
//! ## Example
//!Here is a simple "Hello World" Bevy app:
//! ```
//!use bevy::prelude::*;
//!
//!fn main() {
//!    App::build()
//!        .add_default_plugins()
//!        .add_system(hello_world_system.system())
//!        .run();
//!}
//!
//!fn hello_world_system() {
//!    println!("hello world");
//!}
//! ```

//! Don't let the simplicity of the example above fool you. Bevy is a [fully featured game engine](https://bevyengine.org/learn/book/introduction/features/)
//! and it gets more powerful every day!
//!
//! ### This Crate
//! The "bevy" crate is just a container crate that makes it easier to consume Bevy components.
//! The defaults provide a "full" engine experience, but you can easily enable / disable features
//! in your project's Cargo.toml to meet your specific needs. See Bevy's Cargo.toml for a full list of features available.
//!
//! If you prefer it, you can also consume the individual bevy crates directly.
