+## Accessibility
+
+Sunday Comics is built with accessibility as a core feature, ensuring your webcomic can be enjoyed by all readers, including those using assistive technologies.
+
+### Accessibility Features
+
+#### ✅ Keyboard Navigation
+- **Full keyboard support** - Navigate the entire site without a mouse
+- **Visible focus indicators** - Clear visual outlines on all interactive elements when using Tab navigation
+- **Skip to main content** - Press Tab on any page to reveal a "Skip to main content" link, allowing keyboard users to bypass navigation
+- **Arrow key shortcuts** - Use Left/Right arrows to navigate between comics, Home/End for first/latest
+- **Focus management** - Keyboard focus automatically moves to the comic content after navigation, maintaining context for screen reader users
+
+#### ✅ Screen Reader Support
+- **Semantic HTML** - Proper use of `<header>`, `<nav>`, `<main>`, `<footer>` elements
+- **ARIA live regions** - Screen readers announce when new comics load during client-side navigation
+- **ARIA labels** - All icon buttons and links have descriptive labels
+- **ARIA disabled states** - Disabled navigation buttons properly announce their state
+- **Alt text** - All comic images require alt text (set via `alt_text` field in `comics_data.py`)
+- **No redundant announcements** - Decorative icons use empty alt text to avoid duplicate screen reader announcements
+
+#### ✅ Visual Accessibility
+- **High contrast** - Focus indicators use solid 3px outlines for visibility
+- **Responsive design** - Works across desktop, tablet, and mobile screen sizes
+- **No reliance on color alone** - Disabled states use both color and opacity changes
+
+#### ✅ Additional Accessibility Support
+- **Language declaration** - `lang="en"` attribute on HTML element
+- **Heading hierarchy** - Proper use of h1, h2, h3 throughout the site
+- **Clickable regions** - Comic images that advance to the next comic include descriptive labels
+- **External link safety** - `rel="noopener noreferrer"` on external links
+- **Keyboard trap prevention** - No focus traps; users can always navigate away
+
+### Testing Accessibility
+
+To test keyboard navigation on your site:
+
+1. **Tab Navigation**
+   - Press Tab repeatedly to move through interactive elements
+   - Verify visible focus indicators appear on links and buttons
+   - First Tab should reveal "Skip to main content" link
+
+2. **Keyboard Shortcuts**
+   - On a comic page, press Right Arrow to advance
+   - Press Left Arrow to go back
+   - Press Home to jump to first comic
+   - Press End to jump to latest comic
+
+3. **Screen Reader Testing** (Optional)
+   - **macOS:** Enable VoiceOver (Cmd + F5)
+   - **Windows:** Use NVDA (free) or JAWS
+   - Navigate through the site and verify announcements are clear and logical
+
+### Accessibility Best Practices for Comic Creators
+
+When adding comics to your site, follow these guidelines to maintain accessibility:
+
+1. **Always provide alt text**
+   ```python
+   {
+       'number': 1,
+       'filename': 'comic-001.png',
+       'alt_text': 'A descriptive summary of what happens in the comic',  # Required!
+       # ...
+   }
+   ```
+
+2. **Write meaningful alt text**
+   - Describe the comic's content and context
+   - Include dialogue if it's essential to understanding
+   - Keep it concise but descriptive (aim for 1-2 sentences)
+   - Bad: "Comic"
+   - Good: "Sarah discovers her cat can talk and is planning world domination"
+
+3. **Use proper image formats**
+   - Ensure comic images are clear and readable
+   - Consider providing larger resolution images for zoom accessibility
+   - Test your comics at different zoom levels (200%, 300%)
+
+4. **Structure author notes clearly**
+   - Use markdown headings for long author notes
+   - Break up long paragraphs
+   - Use lists for clarity when appropriate
