Cách sử dụng
A 'footnote' is a small piece of writing at the bottom of a page in a book or document that gives extra information or explains something mentioned in the text. It's like a little note that helps the reader understand the text better. It's often used in academic writing, such as in research papers or textbooks, to provide references or additional details about a topic. When you see a small number or symbol in the text, it means there is a footnote at the bottom of the page that you can read for more information.
