Use vertical lists for lists that are long or contain items on several levels.
Use vertical lists for quick-reference items or for visual prominence.
Use numbers when items on a list follow a specific order.
Use bullets as visual markers for each item.
If the introductory statement is a complete grammatical sentence, end it with a colon. List items do not begin with capital letters and do not carry closing punctuation unless they are complete sentences.
If the introductory statement is not a complete sentence, use the punctuation mark that's appropriate for the context (comma, semicolon, dash, or nothing). List items do not start with capital letters and have no closing punctuation.
Numbered items begin with a capital letter.
Do not use closing punctuation unless the item is a complete sentence.
Separate items in a series with a comma. Do not use a comma before the conjunction.
If the series contains lengthy elements or elements that require separation with a comma, use semicolons to avoid confusion. Use a semicolon before the conjunction in a series.
