### Example

```
use bevy::prelude::*;
use bevy_atmosphere::*;
fn main() {
    App::new()
        .insert_resource(bevy_atmosphere::AtmosphereMat::default()) // Default Earth sky
        .add_plugins(DefaultPlugins)
        .add_plugin(bevy_atmosphere::AtmospherePlugin { dynamic: false }) // Set to false since we aren't changing the sky's appearance
        .add_startup_system(setup)
        .run();
}
fn setup(mut commands: Commands) {
    commands.spawn_bundle(PerspectiveCameraBundle::default());
}
```

Thank you [kbieganski](https://github.com/kbieganski) for your help on the 0.2.0 update!

Big thanks to [glsl-atmosphere](https://github.com/wwwtyro/glsl-atmosphere) and [bevy_skybox](https://github.com/jomala/bevy_skybox), which I essentially tried to merge together

Also thanks to those on the Bevy Discord who took the time to help me
