Our nonprofit, Open Law Library, is working on this exact problem. It is definitely not trivial, but it is very doable. We partner directly with governments to help them implement so the git repos become the canonical record (rather than just an unofficial mirror).

Maryland just launched their regs on our platform:

Feel free to reach out (email in bio) if you would like your community to publish their official laws on GitHub!
