# Markup Reference
> Complete reference for Autype's extended Markdown syntax — standard Markdown plus powerful extensions for professional documents.
Autype uses **standard Markdown** as its foundation and extends it with optional attributes for styling, layout, and professional document features. Everything you know from Markdown works as-is — extended properties are purely additive.
## How it works
Autype supports three syntax layers:
1. **Standard Markdown** — headings, paragraphs, bold, italic, links, lists, tables, code blocks, images, math
2. **Extended attributes** — add `{key=value}` after elements to control styling, alignment, size, and rendering
3. **Directives** — use `:::directive{attrs}` blocks or `::directive{attrs}` one-liners for charts, QR codes, tables with styling, page sections, indices, and bibliography
### Extended attribute syntax
Append `{key=value}` after an element to customize it:
```markdown theme={null}
{width=200 align=center}
```
Values can be strings (`"value"`), numbers (`400`), or booleans (`true`/`false`).
### Directive syntax
**Block directives** wrap content between `:::` markers:
```markdown theme={null}
:::chart{type="bar" title="Sales"}
labels: Q1, Q2, Q3, Q4
dataset: Revenue | 100, 150, 200, 175 | #3b82f6
:::
```
**Inline directives** are single-line with `::`:
```markdown theme={null}
::toc{title="Table of Contents" maxLevel=3}
```
