How do I comment out content in Hugo?
If I have notes, unfinished thoughts, I'd like to leave them in the .md file but not have them appear in the html.
<!-- tags don't seem to work -- it doesn't even become a html comment, it remains visible text on the page.
Hugo uses Go templates under the hood, so the comment syntax is {{/* a comment */}}. Anything inside the comment will not be rendered to the resulting HTML files.
Official doc says, HTML comment does not rendered to final HTML pages.
HTML comments are by default stripped, but their content is still evaluated. That means that although the HTML comment will never render any content to the final HTML pages, code contained within the comment may fail the build process.

So you can use HTML comment like this
<!-- your comment text -->
