## 6.3 Sidenotes

One of the most prominent and distinctive features of this style is the extensive use of sidenotes. There is a wide margin to provide ample room for sidenotes and small figures. Any use of a footnote, of which the Markdown syntax is ^[footnote content], will automatically be converted to a sidenote.

If you would like to place ancillary information in the margin without the sidenote mark (the superscript number), you can use the margin_note() function from tufte in an inline R expression. This function does not process the text with Pandoc, so Markdown syntax will not work here. If you need to write anything in Markdown syntax, please use the marginfigure block described previously.
