First and foremost, it's unlikely that most professional authors would need to use another tool for writing in addition to Microsoft Word. I haven't used Microsoft Word in over a decade; I've been using Linux and Google Docs for about a decade. I hate Microsoft, but I try to be realistic. Nonetheless, Google Docs is a much better tool for most ordinary users than Git. With Google Apps Script you can easily use Google Docs as a CMS (content management system). If indeed your wife actually needs to use Git, instead of teaching your wife markdown, make a bunch of customized headings and explain to her she must not use all of the formatting options in Google Docs. Techies often tend to try to convert ordinary people to "techie technology." It is usually a mistake.
