+# Category Boxes System
+
+This document describes the Wikipedia-style category boxes system implemented for the Fred Hutch Wiki.
+
+## Overview
+
+Category boxes are visual elements that appear at the bottom of articles, helping readers discover related content and navigate between topics. They mimic Wikipedia's category system but are specifically tailored for our scientific computing and data science wiki.
+
+## Quick Start
+
+### For Article Authors
+
+1. Add categories to your article's front matter:
+ ```yaml
+ ---
+ title: Your Article Title
+ layout: single_with_categories
+ categories: ["computing_platforms", "data_storage"]
+ ---
+ ```
+
+2. Your article will automatically display relevant category boxes at the bottom.
+
+### For Category Managers
+
+1. Edit category definitions in `_data/categories.yml`
+2. Each category includes title, description, color, and related links
+3. Changes take effect on next site build
+
+## System Architecture
+
+### Files Structure
+
+```
+wiki/
+├── _data/
+│ └── categories.yml # Category definitions (EDIT THIS)
+├── _includes/
+│ └── category_box.html # Rendering template
+├── _layouts/
+│ └── single_with_categories.html # Auto-includes categories
+├── _scripts/
+│ └── manage_categories.rb # Management utilities
+└── CATEGORY_BOXES_README.md # This file
+```
+
+### How It Works
+
+1. **Category Definitions**: All categories are defined centrally in `_data/categories.yml`
+2. **Article Association**: Articles reference categories by ID in their front matter
+3. **Automatic Rendering**: The `category_box.html` include renders appropriate boxes
+4. **Styling**: Inline CSS ensures compatibility and responsive design
+
+## Available Categories
+
+| Category ID | Topic | Color |
+|-------------|-------|-------|
+| `computing_platforms` | HPC, cloud computing, computational resources | Light blue |
+| `data_storage` | Data storage, management, access | Light purple |
+| `software_development` | Programming, development tools, coding | Light green |
+| `data_science` | Data analysis, visualization, workflows | Light orange |
+| `security_compliance` | Privacy, security, regulatory compliance | Light red |
+| `access_credentials` | Authentication, permissions, system access | Light lime |
+| `bioinformatics` | Genomics, proteomics, biological data analysis | Light teal |
+
+## Usage Examples
+
+### Basic Usage
+```yaml
+---
+title: "Cluster Computing Guide"
+layout: single_with_categories
+categories: ["computing_platforms"]
+---
+```
+
+### Multiple Categories
+```yaml
+---
+title: "Secure Data Analysis Workflows"
+layout: single_with_categories
+categories: ["data_science", "security_compliance", "computing_platforms"]
+---
+```
+
+### Manual Include (if using different layout)
+```markdown
+---
+title: "Your Article"
+layout: custom_layout
+categories: ["bioinformatics"]
+---
+
+Your article content here...
+
+{% include category_box.html %}
+```
+
+## Managing Categories
+
+### Adding a New Category
+
+Edit `_data/categories.yml`:
+
+```yaml
+new_category_id:
+ title: "New Category Name"
+ description: "Brief description of the category scope"
+ color: "#f0f8ff" # Light color for readability
+ links:
+ - title: "Related Article 1"
+ url: "/path/to/article1/"
+ - title: "Related Article 2"
+ url: "/path/to/article2/"
+```
+
+### Updating Existing Categories
+
+1. Modify the appropriate section in `_data/categories.yml`
+2. Update title, description, color, or links as needed
+3. Save and the changes will appear on next build
+
+### Best Practices
+
+- **Limit categories per article**: Use 1-3 most relevant categories
+- **Keep links current**: Regularly review and update category links
+- **Use descriptive titles**: Make link titles clear and consistent
+- **Choose appropriate colors**: Use light, muted colors for readability
+- **Maintain relevance**: Ensure category links genuinely relate to the topic
+
+## Management Tools
+
+### Category Management Script
+
+Use `_scripts/manage_categories.rb` for maintenance:
+
+```bash
+# Validate all categories and links
+ruby _scripts/manage_categories.rb validate
+
+# List all available categories
+ruby _scripts/manage_categories.rb list
+
+# Show articles grouped by category
+ruby _scripts/manage_categories.rb articles
+
+# Find articles without categories
+ruby _scripts/manage_categories.rb orphaned
+```
+
+### Common Maintenance Tasks
+
+1. **Monthly Review**: Run validation to check for broken links
+2. **Content Audit**: Review unused categories and orphaned articles
+3. **Link Updates**: Update category links when articles are moved or renamed
+4. **Category Expansion**: Add new categories as content areas grow
+
+## Styling and Customization
+
+### Color Scheme
+
+Categories use a light color palette for accessibility:
+- Computing: `#e3f2fd` (light blue)
+- Storage: `#f3e5f5` (light purple)
+- Development: `#e8f5e8` (light green)
+- Data Science: `#fff3e0` (light orange)
+- Security: `#ffebee` (light red)
+- Access: `#f1f8e9` (light lime)
+- Bioinformatics: `#e0f2f1` (light teal)
+
+### Responsive Design
+
+Category boxes automatically adapt to mobile devices:
+- Desktop: Inline link buttons
+- Mobile: Full-width stacked buttons
+- All sizes: Proper contrast and readability
+
+### Custom Styling
+
+To customize appearance, edit `_includes/category_box.html`:
+- Modify inline styles for immediate changes
+- Add CSS classes for theme integration
+- Adjust responsive breakpoints as needed
+
+## Troubleshooting
+
+### Category Box Not Appearing
+
+1. Check front matter syntax: `categories: ["category_id"]`
+2. Verify category ID exists in `_data/categories.yml`
+3. Ensure using `layout: single_with_categories` or manual include
+4. Confirm Jekyll is processing the file (not in `_config.yml` exclude list)
+
+### Links Not Working
+
+1. Verify URLs in category definitions
+2. Check that target articles exist
+3. Use correct relative URL format (`/collection/article/`)
+4. Test links after site builds
+
+### Styling Issues
+
+1. Check color codes are valid CSS hex values
+2. Test on different screen sizes
+3. Verify no CSS conflicts with theme
+4. Clear browser cache after style changes
+
+## Integration with Existing Workflow
+
+### Git Workflow
+
+1. Edit categories: Modify `_data/categories.yml`
+2. Update articles: Add `categories` to front matter
+3. Test locally: Build site and verify appearance
+4. Commit changes: Include both category and article updates
+5. Deploy: Changes appear after site rebuild
+
+### Content Strategy
+
+- **New articles**: Consider categories during writing process
+- **Existing articles**: Gradually add categories during content reviews
+- **Category planning**: Align categories with site navigation and user needs
+- **Link maintenance**: Include category links in content review cycles
+
+## Performance Considerations
+
+- **Build time**: Categories are processed at build time (no runtime cost)
+- **Page weight**: Minimal CSS and HTML overhead
+- **Caching**: Category boxes are static content, cache-friendly
+- **Scalability**: System handles hundreds of articles and categories efficiently
+
+## Future Enhancements
+
+Potential improvements to consider:
+- **Tag integration**: Combine with Jekyll tags for enhanced organization
+- **Auto-categorization**: Suggest categories based on content analysis
+- **Category statistics**: Track usage and popularity metrics
+- **Advanced styling**: Theme integration and customization options
+- **Cross-references**: Show related articles within same categories
+
+## Support and Maintenance
+
+For questions or issues:
+1. Check this documentation
+2. Run validation script to identify problems
+3. Review `_data/categories.yml` for consistency
+4. Ask in #wiki Slack channel
+5. Create GitHub issue for bugs or feature requests

Researchers are more and more likely to need to analyze raw data sets using some sort of analysis process before they can be interpreted in the context of the scientific question. Raw data, whether from an array or sequencing for example, are not typically directly interpretable results, thus require some degree of processing. The nature of the processing depends on the data type, the platform with which the data were generated, and the biological question being asked of the data set. How this process is performed depends on the specific project, but support and resources for this process are available at the Fred Hutch for a variety of needs.

The Hutch provides many platforms for storing, using, moving, and sharing your data- relational databases, block-based network file storage, and cloud object datastores. Each of these platforms have options as well- these options to address the diverse needs of modern biomedical and bioinformatic research. The platform you use will depend on the nature of the data and how you plan to use it.

+# Category Boxes Demonstration
+
+This demo article showcases the Wikipedia-style category boxes system implemented for the Fred Hutch Wiki. The category boxes will appear at the bottom of this page, demonstrating how they help readers discover related content.
+
+## What You'll See
+
+At the bottom of this page, you'll find three category boxes:
+
+1. **Computing Platforms** - Links to HPC, cloud computing, and computational resources
+2. **Data Science** - Links to data analysis, visualization, and scientific workflows
+3. **Software Development** - Links to programming languages, development tools, and coding practices
+
+## How It Works
+
+### For Article Authors
+
+To add category boxes to any article, simply:
+
+1. Add `layout: single_with_categories` to your front matter
+2. Include a `categories` array with the desired category IDs
+3. The category boxes will automatically appear at the bottom
+
+Example front matter:
+```yaml
+---
+title: "Your Article Title"
+layout: single_with_categories
+categories: ["computing_platforms", "data_science"]
+---
+```
+
+### For Category Managers
+
+Categories are defined centrally in `_data/categories.yml`. Each category includes:
+
+- **Title** - Display name for the category
+- **Description** - Brief explanation of the category scope
+- **Color** - Background color for visual distinction
+- **Links** - Array of related articles and resources
+
+## Benefits
+
+Category boxes provide several advantages:
+
+- **Discoverability** - Help readers find related content
+- **Navigation** - Easy movement between related topics
+- **Organization** - Thematic grouping of wiki content
+- **Consistency** - Standardized way to show relationships
+- **Maintenance** - Centralized category management
+
+## Visual Design
+
+The category boxes feature:
+
+- **Color coding** - Each category has a unique light background color
+- **Responsive design** - Adapts to mobile and desktop screens
+- **Clear typography** - Easy-to-read titles and descriptions
+- **Hover effects** - Interactive feedback for links
+- **Accessibility** - Proper contrast and semantic structure
+
+## Management Tools
+
+The wiki includes a Ruby script (`_scripts/manage_categories.rb`) for:
+
+- **Validation** - Check for undefined categories and broken links
+- **Listing** - Show all available categories and their usage
+- **Analysis** - Find articles without categories
+- **Maintenance** - Identify unused categories
+
+Run the management script with:
+```bash
+ruby _scripts/manage_categories.rb validate
+ruby _scripts/manage_categories.rb list
+ruby _scripts/manage_categories.rb articles
+```
+
+## Integration
+
+The category system integrates seamlessly with:
+
+- **Jekyll collections** - Works with all wiki sections
+- **Minimal Mistakes theme** - Maintains consistent styling
+- **Existing workflows** - No changes to current editing process
+- **Site navigation** - Complements existing menu structure
+
+## Testing
+
+To verify category boxes work correctly:
+
+1. **Visual check** - Look for boxes at the bottom of this page
+2. **Link testing** - Click links to ensure they navigate properly
+3. **Responsive test** - View on mobile devices
+4. **Validation** - Run the management script
+
+## Next Steps
+
+After implementing category boxes:
+
+1. **Gradual rollout** - Add categories to high-traffic articles first
+2. **Content review** - Identify articles that would benefit from categorization
+3. **Category expansion** - Add new categories as content areas grow
+4. **User feedback** - Monitor how readers use the category system
+
+---
+
+**Note**: The category boxes below are automatically generated based on the categories specified in this article's front matter. They demonstrate the actual functionality you'll see throughout the wiki.

+
+# Category Boxes Guide
+
+This guide explains how to use Wikipedia-style category boxes on the Fred Hutch Wiki. Category boxes help readers discover related articles and navigate between topics more easily.
+
+## What are Category Boxes?
+
+Category boxes are visual elements that appear at the bottom of articles, showing related links grouped by topic. They look similar to Wikipedia's category boxes and help organize content thematically.
+
+## For Article Authors
+
+### Adding Categories to Your Article
+
+To add category boxes to your article, simply add a `categories` field to your article's front matter:
+
+```yaml
+---
+title: Your Article Title
+categories: ["computing_platforms", "data_storage"]
+---
+```
+
+### Available Categories
+
+The following categories are currently available:
+
+- `computing_platforms` - High-performance computing, cloud computing, computational resources
+- `data_storage` - Data storage, management, and access methods
+- `software_development` - Programming languages, development tools, coding practices
+- `data_science` - Data analysis, visualization, scientific workflows
+- `security_compliance` - Data privacy, security, regulatory compliance
+- `access_credentials` - Authentication, permissions, system access
+- `bioinformatics` - Genomics, proteomics, biological data analysis
+
+### Using the Category Layout
+
+To automatically include category boxes in your article, use the `single_with_categories` layout:
+
+```yaml
+---
+title: Your Article Title
+layout: single_with_categories
+categories: ["computing_platforms", "software_development"]
+---
+```
+
+Alternatively, if you need to use a different layout, you can manually include category boxes at the bottom of your article:
+
+```liquid
+{% include category_box.html %}
+```
+
+## For Category Editors
+
+### Editing Category Definitions
+
+Category definitions are stored in `_data/categories.yml`. Each category has:
+
+- **id**: Unique identifier used in article front matter
+- **title**: Display name for the category
+- **description**: Brief explanation of what the category covers
+- **color**: Background color for the category box (CSS hex color)
+- **links**: Array of related articles and their URLs
+
+### Adding a New Category
+
+To add a new category, edit `_data/categories.yml`:
+
+```yaml
+new_category_id:
+ title: "Category Display Name"
+ description: "Brief description of what this category covers"
+ color: "#f0f8ff" # Light blue
+ links:
+ - title: "Related Article 1"
+ url: "/path/to/article1/"
+ - title: "Related Article 2"
+ url: "/path/to/article2/"
+```
+
+### Modifying Existing Categories
+
+To update a category:
+
+1. Edit the appropriate section in `_data/categories.yml`
+2. Modify the title, description, color, or links as needed
+3. Save the file - changes will appear on the next site build
+
+### Color Guidelines
+
+Use light, muted colors for category boxes to ensure readability:
+- Light blue: `#e3f2fd`
+- Light purple: `#f3e5f5`
+- Light green: `#e8f5e8`
+- Light orange: `#fff3e0`
+- Light red: `#ffebee`
+- Light lime: `#f1f8e9`
+- Light teal: `#e0f2f1`
+
+## Best Practices
+
+### For Authors
+
+1. **Be selective**: Choose 1-3 most relevant categories per article
+2. **Stay consistent**: Use established categories rather than requesting new ones frequently
+3. **Think about readers**: Choose categories that help readers find related content
+4. **Test locally**: Preview your article to ensure category boxes render correctly
+
+### For Category Maintainers
+
+1. **Keep links current**: Regularly review and update links in category definitions
+2. **Maintain relevance**: Ensure category links are genuinely related to the category topic
+3. **Limit link count**: Keep 4-8 links per category for optimal usability
+4. **Use clear titles**: Make link titles descriptive and consistent with article titles
+5. **Coordinate changes**: Discuss major category restructuring with the wiki team
+
+## Technical Details
+
+### File Structure
+
+```
+wiki/
+├── _data/
+│ └── categories.yml # Category definitions
+├── _includes/
+│ └── category_box.html # Category box template
+├── _layouts/
+│ └── single_with_categories.html # Layout with automatic categories
+└── articles with categories...
+```
+
+### Styling
+
+Category boxes use inline CSS for maximum compatibility. They are:
+- Responsive (adapt to mobile devices)
+- Accessible (proper color contrast)
+- Consistent with site design
+- Lightweight (no external dependencies)
+
+### Performance
+
+- Category boxes are generated at build time (no client-side JavaScript)
+- Minimal CSS impact
+- Fast loading and rendering
+
+## Troubleshooting
+
+### Category Box Not Appearing
+
+1. Check that your article's front matter includes a `categories` field
+2. Verify category IDs match those in `_data/categories.yml` exactly
+3. Ensure you're using `layout: single_with_categories` or including `{% include category_box.html %}`
+
+### Links Not Working
+
+1. Verify URLs in `_data/categories.yml` are correct
+2. Check that target articles exist
+3. Ensure URLs use the correct relative path format
+
+### Styling Issues
+
+1. Test on different screen sizes
+2. Verify color codes are valid CSS hex colors
+3. Check for any custom CSS conflicts
+
+## Getting Help
+
+For questions about category boxes:
+1. Check this documentation first
+2. Ask in the #wiki channel on Slack
+3. Create an issue in the wiki GitHub repository
+4. Contact the Scientific Computing team
