The content is procedural, conceptual, or rule content.
Manuals contain no logic.
Manuals, because they do not include data, can't do more than provide expository support. Performance support integrates task structuring, data, knowledge, tools and communications. It inherently requires a computer-mediated work context and the ability to integrate logic and data with the content. You might find your approach a little simplistic for sufficient research on which to base any significant paper. Hope this helps.
