Generally, unless each thing being documented is dependent on the one before it, I am not in favor of video. A good example is the PCS competition website. Frequently when I need to figure out or remember how to do something, the only documentation is a video for which sometimes I have to view the entire video to find what I’m looking for as opposed to something that is searchable or at least viewable as a list where tapping it takes you to that documentation topic.
Give me a couple of documentation topics, and I will show you an example of how I would document it. Of course, when there are more topics, I will be able to organize it better by topical area. But the example will be a good illustration.
