How to Create Presentations from Markdown Files

Want to create presentations without PowerPoint or complex tools? If you write in markdown, you already have everything you need. In this guide, you'll learn how to transform your markdown files into beautiful, fullscreen presentations with just a few clicks.

The best part? No exporting, no converting, no separate presentation software needed. Your markdown becomes an instant slideshow right in your browser, complete with syntax highlighting, interactive Mermaid diagrams, math equations, and professional navigation controls.

Why Create Presentations from Markdown?

Markdown presentations offer unique advantages over traditional presentation software:

• Version Control Friendly: Track changes with Git, collaborate through pull requests
• Fast Creation: Write content in plain text without fighting formatting tools
• Code-Friendly: Perfect syntax highlighting for technical presentations
• Reusable Content: Same markdown works as documentation, blog posts, or presentations
• Portable: No proprietary formats, works on any platform
• Diagrams Support: Mermaid diagrams render perfectly in slides

Using MarkView Presentation Mode

MarkView is a browser extension with built-in Presentation Mode that converts your markdown files into professional slideshows instantly. It's the easiest way to present markdown without any setup or configuration.

Step 1: Install MarkView Extension

1. Open your Chromium browser (Chrome, Edge, Brave, etc.)
2. Visit the extension store and search for "MarkView"
3. Install the extension and grant necessary permissions when prompted
4. Enable "Allow access to file URLs" in extension settings (for local files)

Step 2: Prepare Your Markdown File

Create or open your existing markdown file. To split content into slides, use one of these methods:

Method 1: Use Slide Delimiters (Recommended)

# Welcome Slide

Introduction content here

---

# Second Slide

More content here

---

# Third Slide

Final content

Method 2: Use H1 Headings

# First Slide

Content for first slide

# Second Slide

Content for second slide

# Third Slide

Content for third slide

Method 3: Use H2 Headings

## Slide One

Content here

## Slide Two

More content

## Slide Three

Final content

Pro Tip: MarkView automatically detects the best splitting strategy. If you use --- delimiters, it uses those. Otherwise, it looks for H1 or H2 headings (needs at least 3 headings).

Step 3: Enter Presentation Mode

1. Open your markdown file in your browser (drag & drop or Ctrl+O / Cmd+O)
2. MarkView automatically renders your markdown
3. Click the "Presentation Mode" button in the floating action menu
4. Your presentation starts in fullscreen automatically

Step 4: Navigate Your Presentation

Once in presentation mode, use these controls:

Keyboard Shortcuts:

• →, Space, PageDown - Next slide
• ←, Backspace, PageUp - Previous slide
• Home - First slide
• End - Last slide
• 1-9 - Jump to slide number
• F or F11 - Toggle fullscreen
• P - Toggle auto-play
• ? - Show/hide keyboard shortcuts help
• Esc - Exit presentation

Touch Gestures:

• Swipe left - Next slide
• Swipe right - Previous slide
• Tap left edge - Previous slide
• Tap right edge - Next slide
• Tap center - Toggle controls visibility

Advanced Features

1. Auto-Play Mode

Enable auto-play to advance slides automatically:

1. Press P or click the play button
2. Slides advance every 5 seconds (default)
3. Auto-play stops at the last slide
4. Press P again to pause

2. Scroll Indicator for Overflowing Content

When slide content exceeds the viewport height, MarkView automatically shows a scroll indicator with a bounce animation. This helps you know when there's more content to scroll through on the current slide.

3. Code Syntax Highlighting

Code blocks maintain beautiful syntax highlighting in presentation mode:

```javascript
function greet(name) {
  console.log(`Hello, ${name}!`);
  return true;
}
```

MarkView supports 36 programming languages with 14 syntax themes that automatically adapt to your chosen light/dark mode.

4. Mermaid Diagrams

Include flowcharts, sequence diagrams, and other visualizations:

```mermaid
graph TD
    A[Start] --> B{Decision}
    B -->|Yes| C[Action 1]
    B -->|No| D[Action 2]
    C --> E[End]
    D --> E
```

Diagrams render perfectly in slides with automatic theme switching (light/dark mode support).

5. Math Equations

Present mathematical formulas with KaTeX:

$$
E = mc^2
$$

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

Real-World Use Cases

Technical Documentation Presentations

Convert your project README or documentation into a presentation for team meetings. Code examples, architecture diagrams, and API documentation look professional with syntax highlighting and Mermaid support.

Conference Talks & Workshops

Write your entire talk in markdown with speaker notes. Version control your presentation alongside your code examples. Update slides quickly without dealing with presentation software.

Educational Content

Create lecture slides with math equations, code examples, and interactive diagrams. Students can access the same markdown file as both presentation and study guide.

Project Status Updates

Quickly transform project updates from markdown into professional slides. Include task lists, progress charts (Mermaid Gantt), and code snippets.

💡 Pro Tips for Better Markdown Presentations

1. Keep Slides Focused

Each slide should convey one main idea. Use bullet points sparingly (3-5 maximum per slide). Break complex topics into multiple slides rather than cramming everything onto one.

2. Use Visual Hierarchy

# Main Title
## Subtitle or Section
### Supporting Point

Regular text for details

3. Leverage Markdown Features

• Bold text for emphasis
• Inline code for technical terms
• Blockquotes for important callouts
• Lists for organized information
• Code blocks with language specification

4. Test Your Presentation

Before the big day:

• Run through your entire presentation at least once
• Check that all images load correctly
• Verify Mermaid diagrams render properly
• Test keyboard shortcuts and navigation
• Try the help modal (press ?) to review available shortcuts

5. Prepare for Different Screen Sizes

MarkView automatically scales slides to fit any screen, but test on different resolutions if possible. Avoid tiny fonts - presentations should be readable from the back of the room.

MarkView Presentation Mode vs. Alternatives

vs. reveal.js

MarkView: Zero setup, instant presentations from any markdown file, no HTML/CSS knowledge needed

reveal.js: Requires HTML wrapper, more customization but steeper learning curve

vs. Marp

MarkView: Works directly in browser, no CLI tools, perfect for quick presentations

Marp: Desktop app with more export options but requires installation

vs. PowerPoint/Google Slides

MarkView: Write in plain text, version control friendly, instant updates, code-first workflow

PowerPoint/Google Slides: WYSIWYG editing, more design options but slower content creation

Common Issues & Solutions

My markdown isn't splitting into slides

Solution: Make sure you're using one of the three splitting methods:

• Triple dashes (---) as delimiters
• At least 3 H1 headings (#)
• At least 3 H2 headings (##)

MarkView will warn you if it can't detect a clear splitting strategy.

Slide content is overflowing

Solution: MarkView shows a scroll indicator for overflowing slides. To fix:

• Reduce content per slide
• Split into multiple slides
• Use shorter code blocks
• Simplify complex lists

Images aren't loading

Solution: Use relative paths from your markdown file location:

![Screenshot](./images/screenshot.png)
![Diagram](../assets/diagram.png)

Mermaid diagrams not rendering

Solution: Ensure your code block uses the correct syntax:

```mermaid
graph TD
    A --> B
```

Check the Mermaid documentation for valid diagram syntax.
