# Slidev - Presentation Slides for Developers

Web-based slides maker built on Vite, Vue, and Markdown.

## When to Use

- Technical presentations or slidedecks with live code examples
- Syntax-highlighted code snippets with animations
- Interactive demos (Monaco editor, runnable code)
- Mathematical equations (LaTeX) or diagrams (Mermaid, PlantUML)
- Record presentations with presenter notes
- Export to PDF, PPTX, or host as SPA
- Code walkthroughs for developer talks or workshops

## Quick Start

```bash
pnpm create slidev    # Create project
pnpm run dev          # Start dev server (opens http://localhost:3030)
pnpm run build        # Build static SPA
pnpm run export       # Export to PDF (requires playwright-chromium)
```

**Verify**: After `pnpm run dev`, confirm slides load at `http://localhost:3030`. After `pnpm run export`, check the output PDF exists in the project root.

## Basic Syntax

```md
---
theme: default
title: My Presentation
---

# First Slide

Content here

---

# Second Slide

More content

<!--
Presenter notes go here
-->
```

- `---` separates slides
- First frontmatter = headmatter (deck config)
- HTML comments = presenter notes
