Hi @joelnitta! Thanks for this example addition! We've recently updated the lesson to use the workbench. Could you recreate these changes in the workbench format and resubmit the PR to the new main branch?

Also I was thinking to match style, maybe it would be good to have this match the others and link to a separate page. However, yours is nice and short. Perhaps a compromise would be to write your summary like the others do and then put the actual example in a ::: spoiler fenced div?

Thanks!
Sarah
