Bring bevy to the app:

After finishing the Bevy Setup part. You can start coding by adding use bevy::predule::* to the main.rs source file:

use bevy::prelude::*;
 
fn main()
{
	println!("Hello World");
}

By doing this, it will bring all Paths to your main program.

First basic program:

The first and important component you have to have in your program is App:

use bevy::prelude::*;
 
fn main()
{
	App::new()
		.run();
}

Initializes new App by App::new() then .run() it.

You can consider App as the Bevy Program

- World: A storage for game’s data.
- Schedule: a collection of Systems.
- Runner: bases on schedules, the runner controls the broad execution strategy.
