# Markdown Syntax Guide

## Text Formatting

Regular text, **bold**, *italic*, ***bold italic***, ~~strikethrough~~, and `inline code`.

> Blockquotes can contain **formatting** and even
> multiple paragraphs.
>
> > Nested blockquotes work too.

## Headings

> # H1 — Document Title
> ## H2 — Section
> ### H3 — Subsection
> #### H4 — Sub-subsection
> ##### H5 — Minor heading
> ###### H6 — Smallest heading

## Lists

### Unordered
- First item
- Second item
  - Nested item
  - Another nested
    - Even deeper

### Ordered
1. Step one
2. Step two
   1. Sub-step A
   2. Sub-step B

### Task List
- [x] Completed task
- [x] Another done
- [ ] Still to do

## Tables

| Left | Center | Right |
|:-----|:------:|------:|
| L1 | C1 | R1 |
| L2 | C2 | R2 |
| L3 | C3 | R3 |

## Code

```typescript
const { html, flavor } = await renderMarkdown(input);
console.log(`Detected: ${flavor.primary}`);
```

```python
import requests

response = requests.post("https://mdfy.app/api/docs", json={
    "markdown": "# Hello World",
})
print(response.json()["id"])  # → "abc123"
```

## Math (KaTeX)

Inline: $E = mc^2$ and $x = \frac{-b \pm \sqrt{b^2-4ac}}{2a}$

$$
\int_0^{\infty} e^{-x^2} dx = \frac{\sqrt{\pi}}{2}
$$

$$
\begin{pmatrix} a & b \\ c & d \end{pmatrix} \begin{pmatrix} x \\ y \end{pmatrix} = \begin{pmatrix} ax + by \\ cx + dy \end{pmatrix}
$$
