Like this quoted section

you use a "> " before the quote. A greater than and a space.
To end the quote you need to put at least one blank line.

You are using the commands for a "code" section.
Usually used when putting actual programming code into HTML.
Code starts and ends with three back ticks (left of the '1') key - for those who do not know.
