LED Signs

Has anyone else purchased the LED Signs product? I needed help on figuring out how to use it. I find the premade signs in the materials section but from the way the description reads, It sounded like there were individual letters, numbers and symbols I could use to make my own. Any help would be greatly appreciated. Thanks.
