Footnotes

Footnotes are notes that are placed at the end of a page and used to reference parts of the text, providing citations, outside sources and more.

In $\LaTeX$, \footnote is the core command for creating footnotes and it takes two forms:

• \footnote{text for footnote}: This inserts an (automatically-generated) superscript number, called the footnote marker, into the document text and also creates the corresponding footnote at the bottom of the page, containing the corresponding footnote marker and text for footnote.

• \footnote[number]{text for footnote}: The behaviour of this form is exactly the same as the above command, but you can specify the superscript number.

Let's look an at example:

I'm writing to demonstrate use of automatically-generated footnote markers\footnote{Automatically generated footnote markers work fine!} and footnotes which use a specifically chosen value provided to the command \verb|\footnote| \footnote[42]{...is that the answer to everything?}. 

Now, I will use another automatically-generated footnote marker\footnote{Now, footnote markers are 1, 42, but then back to 2? That will be confusing if the automatically-generated number also reaches 42!}.
