+This is _emphasized_

+
+This should be a code block, though:
+
+{code}
+<div>
+    foo
+</div>

+
+As should this:

+<div>foo</div>

+
+Subscripts: H{~2~}O, H{~23~}O, H{~many of them~}O.
+
+These should not be superscripts or subscripts, because of the unescaped spaces: a^b c^d, a~b c~d.

+Here is a footnote reference,[1] and another.[2] This should _not_ be a footnote reference, because it contains a space.[^my note] Here is an inline note.[3]

+
+
+# And in list items.[5]
+
+This paragraph should not be part of the note, as it is not indented.
+
+
+[1] Here is the footnote. It can go anywhere after the footnote reference. It need not be placed at the end of the document.
+
+
+[2] Here's the long note. This one contains multiple blocks.
+
+Subsequent blocks are indented to show that they belong to the footnote (as with list items).

+
+If you want, you can indent every line, but you can also be lazy and just indent the first line of each block.
+
+
+[3] This is _easier_ to type. Inline notes may contain [links|http://google.com] and {{]}} verbatim characters, as well as [bracketed text].
+
+
+[4] In quote.
+
+
+[5] In list.
