--	**Footnotes**, which appear at the end of a document (web page or book chapter). In book parlance, they are therefore actually endnotes, but we call them footnotes because that's what kramdown calls them. To create them in markdown, follow the [kramdown syntax for footnotes](https://kramdown.gettalong.org/syntax.html#footnotes):
+- **Endnotes** appear at the end of a document (web page or book chapter). In technical markdown terms, these are called footnotes, because on the web they appear at the bottom of a web page.

--	**Sidenotes** appear in a box to the right of the text. On wide screens, they might float far right of the text. On narrower screens, the text might wrap around them. In print, the text might wrap around them, too, or they might appear in an otherwise empty sidebar space. To create a sidenote, give the paragraph a `{:.sidenote}` tag. If the sidenote includes more than one paragraph, put them in a `<div class="sidenote" markdown="1"> ... </div>`.
--	**Footer notes**, which in print are sidenotes at the bottom of the page. By adding `.bottom` to the `{:.sidenote}` tag, your sidenote should sit at the bottom of the page rather than on the right with text wrap, replicating a traditional footnote. So the markdown looks like this:
+- **Footnotes** appear at the bottom of the page. To distinguish these from what markdown calls 'footnotes', we sometimes call these 'on-page footnotes'. To create these, use the same syntax as for endnotes (above), but add a `move-to-footnote` class to the footnote text. This section of the samples book demonstrates endnotes with a few on-page footnotes. We only support these in PDF output.
