More complex structures are allowed, but you won’t encounter them typically with Quarto

YAML

Strings don’t need to be quoted…

But, if the string contains any special characters, they must be quoted

title: "Me & my cow"

You can use ' or " quotes, latter most useful

title: "Gavin's amazing paper!"

YAML

To nest elements hierarchically we use indendation

2 or 4 spaces are used, not a tab!

format:
  html:
    toc: true
  pdf:
    keep_tex: true
  docx: default

format is the top level

html, pdf, and docx are second-level elements, etc
