Explain it like I'm 5

I'm looking to take my books off my kindle and putting them on an android tablet.

I am not tech savvy in any regard. So if someone can explain how to accomplish this like I am a five year old, link me a video or even another thread where it's explained that would be absolutely epic.

I thank you in advance.

EDIT: I appreciate everyone who responded. I think you've all covered the information I was seeking. Thank you. 🫶 May your pillow always be cold.
