## Block Math

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

Integration Examples

Integration with npm Project

// package.json
{
  "scripts": {
    "start": "marp -s ./slides",
    "watch": "marp -w ./slides -o ./dist",
    "build": "marp ./slides --output ./dist",
    "build:pdf": "marp ./slides -o ./dist --pdf"
  },
  "devDependencies": {
    "@marp-team/marp-cli": "^3.0.0"
  }
}

Integration with Makefile

SLIDES_DIR = slides
OUTPUT_DIR = dist

.PHONY: html pdf clean serve

html:
	marp $(SLIDES_DIR)/*.md --output $(OUTPUT_DIR)

pdf:
	marp $(SLIDES_DIR)/*.md --output $(OUTPUT_DIR) --pdf --allow-local-files

clean:
	rm -rf $(OUTPUT_DIR)

serve:
	marp -s $(SLIDES_DIR)

Best Practices

1. Project Structure

presentations/
├── slides/
│   ├── quarterly-review.md
│   └── product-demo.md
├── themes/
│   └── corporate.css
├── images/
├── dist/
├── .marprc.yml
└── package.json

2. Slide Template

---
marp: true
theme: corporate
paginate: true
header: 'Company | Title'
footer: '2026'
---

<!-- _class: title -->
<!-- _paginate: false -->

# Presentation Title

**Presenter Name** | *Date*

---

# Agenda

1. Topic One
2. Topic Two
3. Q&A

---

<!-- _class: section -->

# Section 1

---

## Content Slide

- Key point
- Another point

---

<!-- _class: title -->

# Thank You

3. Image Guidelines

<!-- Use consistent sizing -->
![width:800px](./full-width.png)
![width:400px](./medium.png)

<!-- Use relative paths -->
![](./images/diagram.png)

<!-- Include alt text -->
![Architecture diagram](./images/arch.png)

Troubleshooting

PDF Export Fails

# Specify Chrome path
marp slides.md -o slides.pdf --chrome-path /usr/bin/chromium-browser

# Use Chrome arguments for headless environments
marp slides.md -o slides.pdf \
  --chrome-arg=--no-sandbox \
  --chrome-arg=--disable-setuid-sandbox

Images Not Loading

# Enable local file access
marp slides.md -o slides.pdf --allow-local-files

# Use relative paths from markdown file location
![](./images/photo.png)

Custom Theme Not Applied

# Specify theme file path
marp slides.md --theme ./themes/custom.css -o slides.html

# Ensure theme has correct header comment
# /* @theme custom-theme */

Debug Mode

marp slides.md -o slides.pdf --debug
marp --version
