Here is a simple footnote.
A footnote can also have multiple lines.
You can also use words, to fit your writing style more closely[note].
: My reference.
: Every new line should be prefixed with 2 spaces.
This allows you to have a footnote with multiple lines.
Named footnotes will still render with numbers instead of the text but allow easier identification and linking.
This footnote also has been made with a different syntax using 4 spaces for new lines.
