+# Presentation Generation System
+
+This system generates AI-powered presentation slides from lesson content for classroom teaching.
+
+## Overview
+
+The presentation generation system follows the same pattern as the podcast generation:
+
+1. **Parse** lesson MDX content and extract clean text
+2. **Generate** condensed presentation slides using Claude Code CLI (Haiku 4.5)
+3. **Output** structured JSON with slides, speaker notes, and metadata
+4. **Deploy** presentations alongside the Docusaurus site
+
+## Architecture
+
+```
+MDX Lesson → AI Processing → JSON Presentation → Reveal.js → Classroom Display
+```
+
+### Components
+
+- **generate-presentation.js** - AI-powered script generator
+- **RevealSlideshow.tsx** - Reveal.js wrapper component
+- **PresentationToggle.tsx** - Toggle button for docs pages
+- **DocItem/Layout** - Swizzled Docusaurus component that injects the toggle
+
+## Usage
+
+### Generate Presentations
+
+```bash
+# Interactive mode (select file)
+node scripts/generate-presentation.js
+
+# Generate for specific file
+node scripts/generate-presentation.js --file intro.md
+
+# Generate for all files in a module
+node scripts/generate-presentation.js --module understanding-the-tools
+
+# Generate for all lessons
+node scripts/generate-presentation.js --all
+
+# Debug mode (saves AI prompt for inspection)
+node scripts/generate-presentation.js --file intro.md --debug
+```
+
+### View Presentations
+
+1. **In Development**: Navigate to any lesson page and click the "Present" button (🎭)
+2. **Keyboard Shortcut**: Press `P` on any lesson page to toggle presentation mode
+3. **Exit**: Press `ESC` or click the close button (✕)
+
+### Speaker Notes
+
+Press `S` while in presentation mode to open the speaker notes view, which shows:
+
+- Talking points for current slide
+- Timing guidance
+- Discussion prompts
+- Real-world context
+- Transition notes for next slide
+
+## Slide Types
+
+The AI generates different slide types based on content:
+
+### 1. Title Slide
+- Lesson title and subtitle
+- Learning objectives
+- Estimated duration
+
+### 2. Concept Slide
+- Key idea with 3-5 bullet points
+- Progressive reveal (fragment animation)
+- Used for main teaching points
+
+### 3. Code Example Slide
+- Syntax-highlighted code block
+- Caption explaining purpose
+- Up to 15 lines for readability
+
+### 4. Comparison Slide
+- Side-by-side ineffective vs effective patterns
+- Color-coded (red for bad, green for good)
+- Shows contrast between approaches
+
+### 5. Visual Slide
+- Custom React components (CapabilityMatrix, UShapeAttentionCurve, etc.)
+- Interactive visualizations
+- Caption explaining the visual
+
+### 6. Key Takeaway Slide
+- Summary of section or lesson
+- 3-5 main points
+- Reinforces learning objectives
+
+## Customization
+
+### Disable Presentation for a Lesson
+
+Add to frontmatter:
+
+```yaml
+---
+title: "Lesson Title"
+presentation: false  # Hides presentation button
+---
+```
+
+### Reveal.js Configuration
+
+Edit `RevealSlideshow.tsx` to customize:
+
+```typescript
+const deck = new Reveal(deckRef.current, {
+  width: 1280,         // Presentation width
+  height: 720,         // Presentation height
+  transition: 'slide', // Transition effect
+  slideNumber: 'c/t',  // Current/total slide numbers
+  // ... more options
+});
+```
+
+## AI Prompt Design
+
+The presentation prompt focuses on:
+
+1. **Condensation**: 8-15 slides per lesson (vs 50+ paragraphs in docs)
+2. **Visual Focus**: Bullet points, not paragraphs
+3. **Speaker Notes**: Detailed talking points for instructor
+4. **Code Selection**: Only most illustrative examples
+5. **Logical Flow**: Clear transitions between concepts
+
+### Prompt Structure
+
+```
+TASK: Convert technical course material into presentation format
+
+TARGET AUDIENCE: Senior software engineers (3+ years)
+
+PRESENTATION STRUCTURE:
+✓ Create 8-15 slides total
+✓ Each slide covers ONE key concept
+✓ Use bullet points (3-5 per slide)
+✓ Include speaker notes with timing, discussion prompts
+✓ Preserve important code examples
+✓ Identify visual components to use
+
+OUTPUT FORMAT: Valid JSON with metadata and slides array
+```
+
+## Output Structure
+
+### Manifest File
+
+Located at:
+- `scripts/output/presentations/manifest.json` (build-time)
+- `website/static/presentations/manifest.json` (deployed)
+
+```json
+{
+  "intro.md": {
+    "presentationUrl": "/presentations/intro.json",
+    "slideCount": 12,
+    "estimatedDuration": "30-45 minutes",
+    "title": "AI Coding for Senior Engineers",
+    "generatedAt": "2025-01-09T12:00:00.000Z"

+```
+
+## Keyboard Shortcuts
+
+- **P** - Toggle presentation mode
+- **Arrow Keys** - Navigate slides (Reveal.js)
+- **S** - Open speaker notes view
+- **ESC** - Exit presentation mode
+- **F** - Fullscreen (browser)
+- **O** - Overview mode (see all slides)
+
+## Best Practices
+
+### For Content Authors
+
+1. Write detailed lesson content - AI will condense it
+2. Use clear headings (H2) to structure sections
+3. Include code examples with context
+4. Add admonitions (:::tip, :::warning) for important points
+5. Use visual components where appropriate
+
+### For Instructors
+
+1. Review speaker notes before class
+2. Practice timing on key concepts
+3. Use discussion prompts to engage students
+4. Reference real-world examples from speaker notes
+5. Adjust pace based on student questions
+
+### For Maintenance
+
+1. Regenerate presentations after lesson updates
+2. Test presentation display on classroom projector
+3. Verify code examples are readable from distance
+4. Check that visual components render correctly
+5. Review speaker notes for accuracy
+
+## Troubleshooting
+
+### Presentation button doesn't appear
+
+1. Check manifest exists: `website/static/presentations/manifest.json`
+2. Verify lesson path matches manifest key
+3. Ensure `presentation: false` is not in frontmatter
+4. Check browser console for errors
+
+### Slides don't render correctly
+
+1. Verify JSON structure is valid
+2. Check that visual component names match imports
+3. Test with simpler slide type first
+4. Review Reveal.js console errors
+
+### Speaker notes missing
+
+1. Ensure speakerNotes field exists in JSON
+2. Check that all required fields are present
+3. Press `S` to toggle speaker view
+4. Verify browser allows popups (for separate speaker window)
+
+### Code examples too long
+
+1. Edit JSON to shorten code
+2. Regenerate with updated lesson content
+3. Split into multiple code slides
+4. Use caption to reference full code in docs
+
+## Development
+
+### Adding New Slide Types
+
+1. Add type to TypeScript interface in `RevealSlideshow.tsx`
+2. Implement render case in `renderSlide()` function
+3. Add CSS styling in `RevealSlideshow.module.css`
+4. Update AI prompt to generate new type
+5. Test with sample lesson
+
+### Modifying AI Prompt
+
+Edit `buildPresentationPrompt()` in `generate-presentation.js`:
+
+```javascript
+function buildPresentationPrompt(content, fileName, outputPath) {
+  return `You are a presentation script writer...
+
+TASK: Convert technical course material...
+
+PRESENTATION STRUCTURE REQUIREMENTS:
+✓ DO: Create 8-15 slides total
+✓ DO: Each slide should cover ONE key concept
+// ... add your requirements
+
+OUTPUT FORMAT: Valid JSON...`;
+}
+```
+
+## Performance
+
+- **Generation Time**: 30-60 seconds per lesson (depends on length)
+- **Bundle Size**: Reveal.js adds ~60KB gzipped
+- **Slide Load Time**: <100ms for typical presentation
+- **Speaker Notes**: Minimal performance impact
+
+## Future Enhancements
