Ask HN: What information do you consider knowledge in software development?

Hi, I am Dragos, the founder and sole developer of https://archbee.io - a tech team focused knowledge base & wiki.

Right now our editor has plugins like: text, native diagrams, SwaggerUI, GraphiQL, changelogs, maps, callouts, APIs.

What else could be used to express knowledge/documentation/know-how in software development teams?
