+# Slide Modification Guide
+
+Workflows for modifying individual slides after initial generation.
+
+## Edit Single Slide
+
+Regenerate a specific slide with modified content:
+
+1. Identify slide to edit (e.g., `03-slide-key-findings.png`)
+2. Update prompt in `prompts/03-slide-key-findings.md`
+3. If content changes significantly, update slug in filename
+4. Regenerate image using same session ID
+5. Regenerate PPTX and PDF
+
+## Add New Slide
+
+Insert a new slide at specified position:
+
+1. Specify insertion position (e.g., after slide 3)
+2. Create new prompt with appropriate slug (e.g., `04-slide-new-section.md`)
+3. Generate new slide image
+4. **Renumber files**: All subsequent slides increment NN by 1
+   - `04-slide-conclusion.png` → `05-slide-conclusion.png`
+   - Slugs remain unchanged
+5. Update `outline.md` with new slide entry
+6. Regenerate PPTX and PDF
+
+## Delete Slide
+
+Remove a slide and renumber:
+
+1. Identify slide to delete (e.g., `03-slide-key-findings.png`)
+2. Remove image file and prompt file
+3. **Renumber files**: All subsequent slides decrement NN by 1
+   - `04-slide-conclusion.png` → `03-slide-conclusion.png`
+   - Slugs remain unchanged
+4. Update `outline.md` to remove slide entry
+5. Regenerate PPTX and PDF
+
+## File Naming Convention
+
+Files use meaningful slugs for better readability:
+
+```
+NN-slide-[slug].png
+NN-slide-[slug].md (in prompts/)
+```
+
+Examples:
+- `01-slide-cover.png`
+- `02-slide-problem-statement.png`
+- `03-slide-key-findings.png`
+- `04-slide-back-cover.png`
+
+## Slug Rules
+
+| Rule | Description |
+|------|-------------|
+| Format | Kebab-case (lowercase, hyphens) |
+| Source | Derived from slide title/content |
+| Uniqueness | Must be unique within the deck |
+| Updates | Change slug when content changes significantly |
+
+## Renumbering Rules
+
+| Scenario | Action |
+|----------|--------|
+| Add slide | Increment NN for all subsequent slides |
+| Delete slide | Decrement NN for all subsequent slides |
+| Reorder slides | Update NN to match new positions |
+| Edit slide | NN unchanged, update slug if needed |
+
+**Important**: Slugs remain unchanged during renumbering. Only the NN prefix changes.
+
