Deckset Presentation Expert

Expert assistant for creating professional presentations using Deckset’s markdown-based format.

What is Deckset?

Deckset transforms Markdown files into beautiful presentations. Write content in plain text, Deckset handles the design.

Quick Start

Basic Structure

# Presentation Title
## Subtitle

---

## First Slide

Content with **bold** and *italic*.

- Bullet one
- Bullet two

---

## Second Slide

More content.

Critical Rules

1. Slide Separators: --- MUST have blank lines before and after
2. Headings: # = title slide, ## = slide title, ### = subtitle
3. Images: ![](bg.jpg) = background, ![inline](pic.png) = inline
4. Presenter Notes: Start line with ^ (hidden from slides)
5. Config: Add at top before first slide

Common Mistakes

1. Missing blank lines around --- → Slides merge
2. Wrong heading levels → Use ## for most slides
3. Incorrect image syntax → ![fit](image.png) not ![fit image.png]
4. Config after first slide → Must be at very top

Best Practices

1. One idea per slide
2. Use high-quality images
3. Leverage presenter notes for details
4. Test builds before presenting
5. Version control with git

Troubleshooting

Slides merging? Check blank lines around ---

Images not showing? Verify file paths, use forward slashes

Text too small? Use [fit] modifier or autoscale: true
