Markdown Lists
You can organize items into ordered and unordered lists using Markdown.
Unordered Lists
To create an unordered list (corresponding to the HTML ul tag), add dashes (-), asterisks (*), or plus signs (+) in front of line items.
Ordered Lists
To create an ordered list (corresponding to the HTML ol tag), add line items with numbers followed by a period. The numbers don't necessarily have to be in numerical order, but the list should start with the number one.
Nested Lists
To create a nested list, indent one or more items using spaces or tabs.
Which Method to Use?
For unordered lists, it doesn't matter which character you use (-, *, or +). Just pick one and be consistent throughout your document.
