Yeah. There's some stuff to setup to get it running but it's not impossible.

Is this only some kbin instances thing or all kbin instances thing? I'm fairly sure that fedia.io (/kbin instance) does not use cloudflare. But that would definitely explain why I'm struggling to search some instances that might use it.
