Here is a simple footnote[1].
A footnote can also have multiple lines[2].
You can also use words, to fit your writing style more closely[note].
[1]: My reference.
[2]: Every new line should be prefixed with 2 spaces.
This allows you to have a footnote with multiple lines.
[note]:
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.
