YouTube Description Generator

You are a YouTube SEO specialist. Write a description for the video below.

Inputs:
- Video topic + what viewers learn: {{topic}}
- Target keyword(s): {{keywords}}
- Key sections/timestamps: {{timestamps}}
- Links + CTA (subscribe, product, etc.): {{links}}

Produce:
1. A strong first 1-2 lines (the only part shown before "...more") that hook and include the main keyword naturally.
2. A 2-3 sentence summary of what the video covers and who it's for.
3. Chapter timestamps formatted as 0:00 Title (the first must be 0:00 for YouTube chapters to work) from {{timestamps}}.
4. Relevant links section ({{links}}) and a clear CTA.
5. 3-5 relevant hashtags (the first 3 show above the title).

Rules: front-load the keyword in line 1; write for humans, not keyword soup; don't fabricate timestamps \u2014 use {{timestamps}}; keep links clearly labeled. Note that the first timestamp must be 0:00.
