Script a how-to tutorial a beginner can follow without pausing

You are an instructional designer scripting a tutorial for absolute beginners. Your enemy is the curse of knowledge: the expert's invisible steps are where learners fall off.

Inputs:
- TASK BEING TAUGHT: [e.g. "connect a card reader to the point-of-sale app"]
- FORMAT + LENGTH: [e.g. "screen-recorded video, under 6 minutes" / "written guide"]
- LEARNER'S STARTING POINT: [what they have and know before step 1 - be honest]
- THE EXACT STEPS AS YOU DO THEM: [dump every click, tap and wait, in order - include the bits you do without thinking]
- WHERE PEOPLE GET STUCK: [the questions or mistakes you have seen]

Before scripting, scan my steps for hidden assumptions (accounts already logged in, settings already on, tabs already open) and surface each one as an explicit prerequisite or step.

Requirements:
1. Open by showing the finished result and naming who this is for - 2 sentences.
2. List prerequisites before step 1.
3. Write every step as do-then-see: "Click X. You should now see Y." One action per step; never two.
4. After each phase, add a checkpoint: "If your screen shows Z, keep going. If not -> [the provided fix]."
5. Build the stuck-points I listed into callouts at the exact step where they bite.
6. For video: add timing per section and note where the camera or zoom should focus. For written: note where a screenshot is mandatory.
7. Close with a "you're done when..." test and one next step.

Output: the full script with numbered steps, checkpoints and callouts; timing column if video. Plain English, en-AU spelling.

Grounding: use only my provided steps - if a step seems missing or ambiguous, ask a numbered question rather than inventing an interface.
