A markdown list can be created using simple symbols rather than complicated formatting controls. For an unordered list, you can use a hyphen, asterisk, or plus sign before each item. For an ordered list, use numbers followed by periods. You can also create nested lists by adding indentation before sub-items. Lists are useful for organizing instructions, features, notes, requirements, and other information. Because the syntax is simple and readable, lists can be written quickly in text editors and displayed correctly on many Markdown-supported platforms.
