Change documentation from Confluence to something open

[MachLearnPort]

I really enjoy the open-source nature of this project - but perhaps the documentation can be enhanced by not using Confluence. I was trying to take all the markdown and put it into another product, and WikiJS seemed the best. MDwiki may also be a viable option.

Thanks for all your work.

Hello @MachLearnPort !

Thank you for interesting proposals.

WikiJS really looks cool. Since we are using jinja templates it wouldn't be a problem to develop export to it. Maybe this is something you could help us with?

Regarding MDwiki — I was personally using it for a few Knowledge bases in the past (like this one), but it is not supported anymore and has a few XSS vulnerabilities, discovered by a few folks in russian security chats. So we decided to not use it at all.
