+## Position Recommendations
+
+| Position | Best For | Avoid When |
+|----------|----------|------------|
+| `bottom-right` | Default choice, most common | Key info in bottom-right |
+| `bottom-left` | Right-heavy layouts | Key info in bottom-left |
+| `bottom-center` | Centered designs | Text-heavy bottom area |
+| `top-right` | Bottom-heavy content | Title/header in top-right |
+
+## Opacity Examples
+
+| Opacity | Visual Effect | Use Case |
+|---------|---------------|----------|
+| 0.3 | Very subtle, barely visible | Clean aesthetic priority |
+| 0.5 | Balanced, noticeable but not distracting | Default recommendation |
+| 0.7 | Clearly visible | Brand recognition priority |
+| 0.9 | Strong presence | Anti-copy protection |
+
+## Content Format
+
+| Format | Example | Style |
+|--------|---------|-------|
+| Handle | `@username` | Most common for XHS |
+| Text | `MyBrand` | Simple branding |
+| Chinese | `小红书:用户名` | Platform specific |
+| URL | `myblog.com` | Cross-platform |
+
+## Best Practices
+
+1. **Consistency**: Use same watermark across all images in series
+2. **Legibility**: Ensure watermark readable on both light/dark areas
+3. **Size**: Keep subtle - should not distract from content
+4. **Contrast**: Opacity may need adjustment per image background
+
+## Prompt Integration
+
+When watermark is enabled, add to image generation prompt:
+
+```
+Include a subtle watermark "[content]" positioned at [position]
+with approximately [opacity*100]% visibility. The watermark should
+be legible but not distracting from the main content.
+```
+
+## Common Issues
+
+| Issue | Solution |
+|-------|----------|
+| Watermark invisible | Increase opacity or adjust position |
+| Watermark too prominent | Decrease opacity (0.3-0.5) |
+| Watermark overlaps content | Change position |
+| Inconsistent across images | Use session ID for consistency |
