References
To add a numbered superscript like [1] that links to the corresponding item in an automatically generated reference list:
\{\{< note "some markdown text" >}}
Reference list
To insert an ordered list of items generated from the reference instances in the document:
## References
\{\{< footnotes >}}

layouts/shortcodes/footnotes.html
{{ $list := .Page.Scratch.Get "footnotes"}}
<ol class="references">
{{ $key := 1 }}
{{ range sort $list }}
<li id="ref{{ $key }}">{{ . | markdownify }}<br/>
