+Here is a footnote reference,[^1] and another.[^longnote]
+
+[^1]: Here is the footnote.
+
+[^longnote]: Here's one with multiple blocks.
+
+    Subsequent paragraphs are indented to show that they
+belong to the previous footnote.
+
+        { some.code }
+
+    The whole paragraph can be indented, or just the first
+    line.  In this way, multi-paragraph footnotes work like
+    multi-paragraph list items.
+
+This paragraph won't be part of the note, because it
+isn't indented.
