Use quotation marks around the exact line you want to quote.
Keep the wording, spelling, and punctuation exactly as in the original.
If the quote is part of a longer paragraph, add an ellipsis to show omitted words.
If you add or change anything, put the added words in brackets.
If the quoted line ends with punctuation, place the punctuation inside the quotation marks.
Cite the source if required by the style you are using.
