Frequently asked questions

Why does Markdown formatting need Prettier?

Markdown has many ambiguous rules. Prettier enforces consistent spacing, list markers, link wrapping, and code-fence style — useful for repos with multiple contributors.

What does "Prose wrap" do?

Preserve keeps your line breaks. Always wraps lines longer than the Print width. Never joins each paragraph onto one line.

Will it modify the rendered output?

No — Prettier never changes the rendered HTML, only the source formatting. The rendered Markdown is byte-identical before and after.
