How to Read Wiki Refs?

Wiki will use a citation notation of which I am unfamiliar and it is not intuitive. What does the “^” symbol mean at the start of a cite? OK, in FB it means something about the post above. If this is any bit related, I don’t get what it means especially when it appears at the start of the very first cite! Or, even say the very first five cites? Also, they don’t seem to use footnotes in the articles, or even college notation, to match the text with the refs. Anyone have a clue how to understand Wiki references?

The little ^ symbol is a thing you can click on. It jumps you back to the place where the footnote was referenced.

Not sure what this means. They use superscripted numbers[sup][1][/sup] to indicate footnotes. You can click on the superscript to go immediately to the footnote. Then click on the ^ in the footnote to go back.
