I actually recently introduced RST and Sphinx to our documentation team of 4 non-developers, and the most difficult hurdle was actually teaching them to use git (even with GUI SourceTree). Getting multiple non-developers (2 are remote) how to install Xcode and Docker produced more confusion then I thought it would. We've finally gotten into a flow, and better documented how to install the documentation tools, and it's been working quite well.
