 This application lends itself to a presentation method similar to the [Takahashi method](https://en.wikipedia.org/wiki/Takahashi_method) where you have a concise slides with very little text. The created presentations are more complex than the Taskahashi method but it is still purposefully designed to keep things simple by only having one type of content per slide, be that text, a command output, or something else.
 
 The result is that with this application backend demos should be much easier to create and run whilst also being slightly more engaging.
