What would be best is for you to poke around the site a bit and get familiar enough with it to decide if you'd like to be a part of the community or not. If so, you're welcome! you aren't the first person to feel a bit lost here as a new user, because the site is rather minimal and cryptic—but your eyes will adjust if you keep reading it over time.
If, on the other hand, you're not interested, that's totally ok, but then please don't try to promote your projects here. HN is a community, and the way to get attention for your things is to first give attention to other people's things.
I don't want to specify X, Y, Z criteria technically because that would just be an invitation to game the system. Worse, Gemini will then tell you "first do X, then do Y and Z, and then you'll get that 'real quality feedback'".
What I want Gemini to tell you (and everyone else!) is "don't use Hacker News primarily for promotion - they have a rule against that. Instead, participate in the community for the intended reason—intellectual curiosity—and after a while, it will become clear how the culture works and how to share your projects there".
