TLDR: In our project, communication and documentation are closely linked, and have a foremost place in our OSH. I'm detailing in the link how to document only in one place using markdown, and generate reports, docs, graphs, block diagrams and presentations on the fly.

I'm so lazy about documenting, that I want to do it clean, and efficient - so I have prepared a lazy documentation about it there: http://kelu124.github.io/echomods/DocumentationProcess.html
