Ask HN: Deciding between Ask HN and Show HN

Hi everyone! I almost finished writing yet another bookmark manager in go. It's a little website i wrote to learn go, but i keep stumbling into problems related (i guess) to go. What is more appropriate to ask for help? should i post as - ask hn, describe my problem and eventually put a link to github - ask hn, describe my problem in detail, avoid any link - show hn, link to github and describe the problem in readme
