I have a folder in /root/files and I want to serve it directly to the internet , so I can access it as an direct link, any idea how to do so ? example.com/files/

Right now I am using notion to save a lot of my coding, I often found myself got a lot of bugs /errors, and need to restore back the previous version, unfortunately notion free options only allow 7 days version of history, if my previous code was 1 months ago, it can't restore at all.

So any self host option for notes with revision history in this case ? I don't like to use github since it's complicated to me with all those commands, I prefer something like notes to save my code.
