Can anyone point me to a ShowHN first post policy documentation?

edit: project link is https://github.com/upwindchange/Autai

I had an open source project launching but I found out that I cannot make ShowHN post, the explanation given to me is very vague, I am not sure what should I do to get myself qualified? Is there some quantized instruction like "how many days the account should be registered" or "how many posts/comments/upvotes" the account should get qualified? Thank you for your guidance.
