What you'll learn
- Where it goes wrong: Unmarked pasted text competes with your instructions. Fence it in.
- Fence the text: Tag the material, then give the instruction after it, pointing at the tag by name.
- Name your tags: Named tags let you give instructions about specific pieces of text.
- A tagged prompt: Instructions → fenced material → rules that point at it → format.
- Bad fences: Every fence needs a start AND an end.
- Multiple documents: One tag per document, with an id you can refer to.
