In general, bulleted list items begin with a capital letter and only end in a period if all items form a complete sentence.

Note: Each list should be capitalized and punctuated consistently even if there is a mix of complete and incomplete sentences. If the list contains mostly incomplete sentences, then no item should end in a period.
