For example, if I want to collaborate on making a (non-computer related) textbook with someone, and we want to use git as a version control system. Should we use github/codeberg for this or is there a platform that’s more suitable for using git in nontechnical contexts?
Much easier to keep the content in plain text as markdown/LaTeX/whatever markup language and then use pandoc or pdflatex to convert it to docx/odt/pdf/HTML/whatever as needed.
