This template is very unintutive for someone who just does it for the first time.
I raised a bunch of questions here: https://github.com/huggingface/transformers/issues/7208 1

a complete template that shows a very perfect entry with multiple entries where array is expected/supported
a document that explains each field’s format and variations.

I think it’d make things easier if we had:

template with just fields and no values
a complete demo template that shows a very perfect entry with multiple entries where array is expected/supported
a document that explains each field’s format and variations.

currently the template is also an instruction document and it doesn’t work well.
