Simple numbered footnotes
Add a numbered marker `[^1]` where a source belongs `[^1]:` (same number but with a colon in the end)
in the end of the note to describe the source. The rendered view links the reference and keeps every source together below the content.
These ` are backticks (or grave accents), the standard character in Markdown to start or end inline code-blocks.
Find a tutorial here on where to find the backtick on your keyboard.
Did you see you can put a source inside another source, like in the screenshot below?
In this example, we used a short video of a statement of Allan Savory as source 1, and
within the source footnote itself, we linked another source, the original full video
(2: The documentary "Return to Eden") the short clip was taken from.
