Bullet points
Start each line with -, * or + followed by a space. Pick one marker and stick to it: switching markers starts a new list.
Numbered lists
Use a number followed by . or ). Only the first number matters: 1. 1. 1. renders as 1, 2, 3, which makes reordering easy. Starting at 7. makes the list begin at 7.
Nested lists
Indent the child items so they line up with the text of the parent item: 2 spaces under - , 3 under 1. . Four spaces works in most renderers too.
Paragraphs and code in a list item
Leave a blank line and indent the continuation to the same text column. The same rule lets you put a fenced code block inside a step.
Stopping a list
Two lists back-to-back merge. Put an HTML comment <!-- --> between them to split them.
A number that isn’t a list
A line like 2026. What a year. becomes a list. Escape the dot: 2026\. What a year.
