One of these things is... well in this case they are the same GitHub #Markdown file, one presented remotely using http://Docsify-This.net (which is perfect for embedding) and in the other presented within a http://Docisify.js.org Open Publishing Starter Kit which holds the file.

@hibbittsdesign so…embedding with docsify-this…I presume that’s still an iframe?
@Cmadland It could be, and also using external URL tools like available in Moodle etc. Any particular scenario in mind?
@hibbittsdesign with a Bookdown course, embedding is all or nothing. But it might be nice to have some spare .Md files for loading into different places in Moodle. Maybe each assignment is a standalone Md file…
@Cmadland If your Bookdown pages only used standard MD, you could even use Docsify-This to reuse the same content in different contexts. Docsify-This will automatically remove any Frontmatter when displaying content.
@hibbittsdesign bookdown uses .Rmd, which IS Md, but special…I guess. Will test.
