Turn the job you always forget something on into a phone checklist

Help me turn a job I repeat into a checklist so I stop forgetting things.

The job: [e.g. packing for the kids' swimming, closing up the caravan for winter, setting up my market stall]
How often: [e.g. every Saturday]
What I do now, roughly in order: [list it]
Things I've forgotten before: [e.g. goggles, turning the gas off, the card reader charger]
Who else does it sometimes: [e.g. my partner]

Before you start, ask me up to 3 short questions if anything important is missing. Wait for my answers.

Then:
1. A checklist in the order I'll actually do it, one short line per item, no more than 20 lines.
2. The things I've forgotten before, marked so they stand out.
3. A "do the night before" section if any steps can move earlier.
4. A one-line final check before I walk out of the door.
5. The checklist again as plain lines with no numbers or symbols, ready to paste into a notes app.

Only use what I've typed, and don't add items I didn't mention unless you mark them as suggestions. UK English.
