Whenever bulleted and numbered lists are included in the content, use the appropriate tools in the publishing software for this purpose, rather than entering dashes or numbers from the keyboard with carriage returns.
Use a numbered list when the order of items is important, in other words the information will not be understood if the items are written in a different order (steps for following a recipe, items classified in alphabetical order, etc.).
Use a standard bulleted list when the order of items is unimportant.
