Can You help find a youtube video for me?

I am asking if there is a tutorial on youtube which explains the DataStoreService, and stuff including learning how to send data from multiple places inside of a single game (for example, Hexaria sends the player's character's data into another place, at least I think there are multiple Places because in between areas, there is a loading thing, which I think signifies the entrance into another game) to a different place within the game.
