"Format in Instruction Manuals: Applications of Existing Research" article
This article discusses “visual” and “verbal” pictures and charts in instruction manuals. Second, this article also discusses “typographic cueing” (changing the text and spacing to make the document look better). There are also schema (outlines, diagrams, flowcharts, or models). There is also chunking, which “is the process of grouping related data into meaningful units.” Pictures should be added to instruction manuals, to help the users understand content better.
