With all due respect, this looks like an early-stage project. If everyone adopts such a dismissive attitude, Show HN might as well not exist.
This doesn't imply that you can't share rough, buggy prototypes. It just means that before you do, it would be expected that you spend more time guiding people to get up and running and pointing out possible pitfalls.
I'd argue that in many cases this doesn't even take that much time and yet is the single most important thing you can do when sharing.
Note: I'm just addressing your general point and not making a comment on xiki's install process in particular.
