One of the things I do for a living is write documentation. I have the privilege of supporting a lot of different types of users. And within each type of user, there is variability.
For every document I write, there are always a couple people for whom my document fails. It's not because they're stupid, or because I am. It's because communication is hard, and different perspectives change how information is processed. In addition, in many cases, there's simply a different use case that my document didn't account for because I didn't think of it or run into it.
So much of the time, I need to amend documents after the fact. I may need to clarify a statement, or provide alternate instructions. Often it's a detail that I thought should be universal but wasn't. And often users will simply have done something different beforehand, or out of order, or in some way not in accordance with the intended instructions.
Therefore, if I want a user to be successful with my document, it has to be complete, and thorough, and be tested by different people. It needs to not make assumptions, and it needs to be clear and concise so it can be followed in one go.
If you start getting fancy and make 50 different documents for different steps, because "logically" that makes more sense, what you will find is the user will run into a problem that the two separate documents didn't consider when taken together. Then the user will stop and try to find someone to fix their issue.
If you don't want to be tied up in support calls your whole life, one complete document is the best solution. And if you're a user who just wants to try out some sample tutorial, one complete document is the most likely to work for you without taking up more of your time.
The YouTube video that shows you installing the IDE is superior to one that doesn't. And for pete's sake you can always skip through it.
