I don't really understand how to make plugins use YAML, so if I wanted to make it so that players could add themselves to a file like this, what would I do? I just don't get how to make it read and write to the YAML file. I would like to make it possible that users can add or remove themselves from multiple lists. List1: - Player1 - Player2 List2 - Player3 List 3 - Player1 - Player3 - Player4
