In the next projects, we will learn more about how to animate our characters. However, this package already comes with animations, and if you are up to the challenge, you can try to explore the animation system by yourself. Here a little hint is to select all the sprites that compose an animation and drag them in the scene. Unity will ask you to save the animation file, and I'd suggest you create another folder for those. Then, the characters should already be good to go. From there, you can see the effects of animating a character.

In any case, you can keep reading this book, and come back here later.
