How can I save Player Data?

Hey guys, I am creating a Tycoon. I want it to save the player data. This is like Blood Moon Tycoon. When a player walks into his/her Tycoon it automatically saves the progress. Creating this is so difficult. I created a few of these questions and only got a Wiki Page. I used the Scripting Helpers page, this still didn't work. My main problem is the DataStoreService. According to the instructions of this website, I have to load it in. How? I just want a script and instruction on where to put it. This is so confusing! Any ideas. If you are going to give me a link, give me one that shows how to do this for a begginer. For example if it says "Load the DataStoreServices", can you give me a link that explains how.
