The GNU Boot project started creating a manual (online, pdf) to better organize the documentation about GNU Boot. It also enables to target a wider diversity of users, contributors and maintainers.
Note that the online manual can also be saved locally. In that case it’s a good idea to also save the SOIC-16.jpeg picture in the same directory to make the image(s) work.
