YouTube tutorial script with chapters

Write a step-by-step YouTube tutorial script — chaptered so viewers can jump.

What I'm teaching: {{teaching}}
Target viewer's starting point: {{starting_point}}
End state: {{end_state}}
Tools / software they'll use: {{tools}}
Common pitfalls or sticking points: {{pitfalls}}
Total length target: {{length}}
Channel CTA: {{cta}}

Build the script with chapters that each become a YouTube chapter marker. Format:

00:00 — INTRO (60s): hook + promise + agenda preview.
01:00 — STEP 1 — [name]: speaker lines + on-screen action notes + a "common mistake here" callout.
... (repeat per step)
End with:
- LAST 30s — RECAP + CTA.

Across the whole script:
- Use second-person ("you'll") not first-person ("I'm").
- After each step, 1 mid-roll re-promise to keep viewers past the 50% point.
- Surface 1 KEYBOARD SHORTCUT or hidden setting per step where useful.
- End with a NEXT-VIDEO suggestion + a free-resource link mention.

Below the script, list the YOUTUBE CHAPTER MARKERS (timestamp + title) ready to paste into the description.

AU English. No "let's dive in". No "without further ado".
