Callouts

Callouts make a block of text visually distinct while keeping it in Markdown. Use them for notes, warnings, questions, summaries, and action items that should stand apart from the main flow.

Basic syntax

Copy> [!note]
> This is a note callout.

> [!warning]
> Review this before changing the vault structure.

OpenOnyx renders common callout types in preview and preserves the underlying Markdown.

Good uses

Use callouts for:

• Important constraints.
• Warnings before destructive work.
• Temporary questions.
• Decision summaries.
• Examples that interrupt the main narrative.

Avoid overuse

If every paragraph is a callout, none of them stand out. Convert repeated callouts into headings or sections once the note matures.

Callouts and portability

Callout syntax is readable as a blockquote in plain Markdown tools. That means the content remains available even when a reader does not support callout styling.
