Hello again!

This part of the series describes how to reference *interpolated* strings
inside Markdown documents.

There's a section at the end about eliminating the table of contents from a
reusable document template. I would have preferred using setups, rather
than redefining the \completecontent macro, but didn't see an obvious way
to do so.

Thoughts?
