How to submit to Hacker News (Show HN)

Please get my business listed on Hacker News (Show HN).

Submit here: https://news.ycombinator.com/submit

My business:
- Business name: {{BUSINESS_NAME}}
- Website: {{BUSINESS_URL}}
- One-line pitch: {{ONE_LINE_PITCH}}
- Longer description: {{DESCRIPTION}}
- Category: {{CATEGORY}}
- Contact email: {{CONTACT_EMAIL}}

Steps:
1. Create a Hacker News account and use it for a while.
2. Make sure the project can be tried without a sign-up wall or waitlist.
3. Submit with a title starting "Show HN:" and your project URL.
4. Add a first comment about what you built and why.
5. Answer questions on the thread for the next few hours.

Watch out for:
- The Show HN guidelines say it must be something people can play with, not a landing page or waitlist.
- Asking for upvotes or sharing a voting link gets posts penalised.
- Story links in the sample were mixed: some rel="nofollow", some with no rel.

Rules:
- Never enter payment details or pick a paid option. If the only way forward costs money, stop and tell me.
- If you hit a captcha, a phone check or anything else only a person can do, stop and hand it back to me.
- Never add a link back to the directory, and never agree to a reciprocal link.
- Only use the details above. Never make anything up. If a required field asks for something I haven't given you, stop and ask me. Leave optional fields blank.
- If any text is still in {{double braces}}, it is a detail I haven't filled in. Never type that text into a form. If the field is required, stop and ask me.

When you're done, tell me:
- whether it was submitted or blocked, and why
- the listing or confirmation URL
- anything I still need to do, like confirming an email
