Ask HN: How to Visually Design Tutorials?

I like to write articles about technology or to create tutorials.

I'm starting to feel the need to know how to structure them visually in a way that makes the right information standout. Sorry, if this is not very clear.

For example, I find that just using headings is not enough for this.

Does anyone have any reading resources about how to use design to improve readability? I think that's basically what I need.
