 and `loadParallaxImage` so that it automatically uses your game's image cache instead of the global
 one. The same goes for the `ParallaxComponent` file, but that provides `loadParallaxComponent`.
 
+If you want a fullscreen `ParallaxComponent` simply omit the `size` argument and it will take the
+size of the game, it will also resize to fullscreen when the game changes size or orientation.

 Three example implementations can be found in the
 [examples directory](https://github.com/flame-engine/flame/tree/main/examples/lib/stories/parallax).
