Scrolling text to intro of my game.

Okay so I have been learning unity for some time now and I’ve create my start menu with functional buttons and the start of my game but I would like to add a screen between the start menu and the actual game that gives a little scrolling description of the character his life and some description of what he needs to do (Kinda like a star wars type scrolling) and then at the end it’ll load into the game. I’ve been looking online and cant find much about the specifics of what I want to do. Any help will be greatly appreciated!
