I would have found it helpful to provide a quick summary of the key points at the end. Of course it's best to learn the function of the commands in the context but when you want to apply it it's difficult to search for it. Like they do in the sw carpentry tutorials (e.g. https://swcarpentry.github.io/python-novice-inflammation/08-func/index.html). Then you know immediately if the chapter will help with your problem
Yep I'm definitely +1 for this suggestion.
It is the same thing I advocated for with the aiida-core tutorials/how-tos.
I'm reminded of IMO a good approach to presentations:
Summarise what you are going to tell them
= Tell them it
This is a suggestion from @mpougin
I think this is a great suggestion.
