Where to get info on the jumbotron, to convert to a text/graphics display

I know how to change the color, as well, how to install a background image to the jumbotron.

I want to accomplish creating a static and/or a dynamic marquee.

I’m guessing this is done with the ‘slider’.

An example of this: https://www.vaporbeast.com/

If there is a video or instructions on how to do this, I would appreciate your advise.

Thanks, Bryce
