'Seeing is understanding'
Who reads an instructional booklet? And as one reads, not everyone understands what is meant. Often many chapters are skipped. It is better to show instructions!
Visuals are much more understandable, even if you don't speak Dutch (very well).
Installing a new machine, the replacement of components in a device, the application of a method: An instructional video is the best choice in order to explain: Seeing is understanding!
