I settled on mediawiki myself due to basically how trustworthy mediawiki and mediawiki skins look. I use https://github.com/CanastaWiki/Canasta-DockerCompose myself but the default includes caddy, which I just overrode in the docker compose override. I believe Canasta is mainly driven by someone who works on a wiki farm.

I also know of https://github.com/nasa/meza.

However, I want to repeat my recommendation of miraheze. When I run into an issue or need an extension, I just look at what miraheze does or what people associated with miraheze do. I also believe that due to the nature of mediawiki it’s a better use of resources to have a wiki farm as opposed to many separate instances. If they will host your wiki, I think they’re the best choice.

Do you need to host it yourself? https://miraheze.org/ may do hosting for you

I took a quick skim. By toxic atmosphere, they mean as in probable health hazard, not as in directly killing people immediately.

Indoor co2 levels can easily hit 1000+ ppm co2, especially if your dwelling is well sealed, as many energy efficient dwellings are. Submarines keep co2 at the thousands ppm for extended periods and were the impetus for co2 studies on how much humans can take.

I don’t think a major concern of rising atmospheric co2 is the direct threat to health caused by elevated co2 levels. I, personally, would be angered if someone told me that high co2 levels were dangerous to human health and then I read this.
