Quoting, dividing, and escaping
Blockquotes prefix lines with >. They can nest (>>) and can contain any Markdown — headings, lists, code blocks, even other blockquotes. Use them for citations, callouts, and quoted dialogue.
Horizontal rules are three or more -, *, or _ on a line by themselves. They produce an <hr> element. Spaces between the characters are allowed (- - -).
Escaping special characters
Precede any Markdown special character with a backslash to display it literally. The full set: \ ` * _ { } [ ] ( ) # + - . ! |. If you've ever typed 5*5*5 and gotten weird italics, this is your fix: 5\*5\*5.
HR vs front matter: three dashes (
---) at the very top of a file is usually parsed as the start of YAML front matter, not as a horizontal rule. Put your first HR after at least one paragraph of content.
