Yes that video was mostly about making something boring into making it fun, but that wasn't why I showed it to you. If you remembered, the people when they first started using the piano steps were wary of it. However as they saw others using it, they did as well. Those people learned by example.
That's how people learn in general. If it's just words without pictures or a video, people don't learn things as easily. Therefore be like Lindy and use a lot of screen recordings and screenshots to help teach others :)
