The main initial discussion of MySt Markdown is here: https://myst-nb.readthedocs.io/en/latest/use/myst.html#writing-myst-markdown, which provides a link to the "full" syntax guide: https://myst-parser.readthedocs.io/en/latest/using/syntax.html

But yes if you think it would be helpful to copy a few examples from their, into the MyST-NB section, sounds good. Do you want to make a PR?

There is also syntax examples in: https://myst-nb.readthedocs.io/en/latest/examples/basic.html#syntax
