Lists are effective because they communicate information quickly, at a glance.
Lists are appropriate whenever three or more related pieces of information are presented. Introduce a list with a statement that establishes the context and tells readers what the list is about. Make lists easier to read by leaving space between the items, especially if any item is more than one line long. Avoid clutter by using neutral symbols to mark items. Use end punctuation only when at least one item contains more than one complete sentence.
