# Quarto Authoring

> This skill is based on Quarto CLI v1.9.36 (2026-03-24).

## When to Use What

Task: Write a new Quarto document
Use: Follow "QMD Essentials" below, then see specific reference files

Task: Add cross-references
Use: [references/cross-references.md](references/cross-references.md)

Task: Configure code cells
Use: [references/code-cells.md](references/code-cells.md)

Task: Add figures with captions
Use: [references/figures.md](references/figures.md)

Task: Create tables
Use: [references/tables.md](references/tables.md)

Task: Add citations and bibliography
Use: [references/citations.md](references/citations.md)

Task: Add callout blocks
Use: [references/callouts.md](references/callouts.md)

Task: Add diagrams (Mermaid, Graphviz)
Use: [references/diagrams.md](references/diagrams.md)

Task: Control page layout
Use: [references/layout.md](references/layout.md)

Task: Use shortcodes
Use: [references/shortcodes.md](references/shortcodes.md)

Task: Add conditional content
Use: [references/conditional-content.md](references/conditional-content.md)

Task: Use divs and spans
Use: [references/divs-and-spans.md](references/divs-and-spans.md)

Task: Configure YAML front matter
Use: [references/yaml-front-matter.md](references/yaml-front-matter.md)

Task: Find and use extensions
Use: [references/extensions.md](references/extensions.md)

Task: Apply markdown linting rules
Use: [references/markdown-linting.md](references/markdown-linting.md)

Task: Choose or configure a compute engine (knitr, jupyter, julia)
Use: [references/engines.md](references/engines.md)

### Migration (only when converting an existing project)

Do NOT read these references when writing new Quarto documents.
Only read the one matching the source format when the user explicitly asks to convert or migrate an existing project.

- R Markdown (.Rmd) to Quarto: [references/conversion-rmarkdown.md](references/conversion-rmarkdown.md)
- bookdown project: [references/conversion-bookdown.md](references/conversion-bookdown.md)
- xaringan slides: [references/conversion-xaringan.md](references/conversion-xaringan.md)
- distill article: [references/conversion-distill.md](references/conversion-distill.md)
- blogdown site: [references/conversion-blogdown.md](references/conversion-blogdown.md)
- Jupyter notebook (.ipynb) to/from Quarto: [references/conversion-jupyter.md](references/conversion-jupyter.md)

## QMD Essentials

### Basic Document Structure

```markdown
---
title: "Document Title"
author: "Author Name"
date: today
format: html
---

Content goes here.
```

A Quarto document consists of two main parts:

1. **YAML Front Matter**: Metadata and configuration at the top, enclosed by `---`.
2. **Markdown Content**: Main body using standard markdown syntax.

### Divs and Spans

Divs use fenced syntax with three colons:

```markdown
::: {.class-name}
Content inside the div.
:::
```

Spans use bracketed syntax:

```markdown
This is [important text]{.highlight}.
```

Details: [references/divs-and-spans.md](references/divs-and-spans.md)

### Code Cell Options Syntax

A code cell starts with triple backticks and a language identifier between curly braces.
Code cells are code blocks that can be executed to produce output.

Quarto uses the language's comment symbol + `|` for cell options. Options use **dashes, not dots** (e.g., `fig-cap` not `fig.cap`).

- R, Python, Julia: `#|`
- Mermaid: `%%|`
- Graphviz/DOT: `//|`

````markdown
```{language}
#| label: fig-example
#| echo: false
