"Footnotes" is a Jekyll plugin that helps inserts footnote reference and body HTML, with automatic numbering, if desired.

This plugin is necessary if you want footnotes with markup, but Maruku would suffice if you will use plaintext notes exclusively.

Install

cd /root/of/site
mkdir -p _plugins
wget -O _plugins/footnote.rb "https://raw.github.com/beneills/jekyll-footnotes/master/footnotes.rb"

Automatic numbering:

hello{% fn %} world{% fn %}
{% footnotes %}
   {% fnbody %}
      <p>salut</p>
   {% endfnbody %}
   {% fnbody %}
      <em>monde</em>
   {% endfnbody %}
{% endfootnotes %}

Custom numbering:

hello{% fn 3 %} world{% fn 5 %}
{% footnotes %}
   {% fnbody 3 %}
      <p>salut</p>
   {% endfnbody %}
   {% fnbody 5 %}
      <em>monde</em>
   {% endfnbody %}
{% endfootnotes %}

Do not mix custom and automatic numbering (although it will work if you only use custom numbers above the highest automatic one).

Only numeric IDs are allowed currently. Other IDs will work if you modify the HTML snippets below to remove

We generate valid HTML5
