+## Footnotes
+
+Footnotes are supported as part of the Markdown syntax. Here's one in action. Clicking this number[^fn-sample_footnote] will lead you to a footnote. The syntax looks like:
+
+{% highlight text %}
+Clicking this number[^fn-sample_footnote]
+{% endhighlight %}
+
+Each footnote needs the `^fn-` prefix and a unique ID to be referenced for the footnoted content. The syntax for that list looks something like this:
+
+{% highlight text %}
+[^fn-sample_footnote]: Handy! Now click the return link to go back.
+{% endhighlight %}
+
+You can place the footnoted content wherever you like. Markdown parsers should properly place it at the bottom of the post.
