+   - [ ] Rides system
-   - Add inline code documentation
+   - [ ] Reviews system
+   - [ ] Companies system
 
-4. Future Enhancements
+2. Template Updates:
-   - Branch locking mechanism
+   - [ ] Park list view
-   - Advanced merge strategies
+   - [ ] Ride detail/list views
-   - Custom diff viewers
+   - [ ] Review detail/list views
-   - Performance optimizations
+   - [ ] Company detail/list views
+
+## Immediate Next Steps
+1. Model Integration (Priority)
+   ```python
+   # Add to rides/models.py:
+   class Ride(HistoricalModel):
+       # Update save method
+       def save(self, *args, **kwargs):
+           from history_tracking.signals import get_current_branch, ChangesetContextManager
+           # Add version control logic
+   ```
+
+2. Template Updates
+   ```html
+   <!-- Add to each list template -->
+   {% if version_control.vcs_enabled %}
+   {% include "history_tracking/includes/version_status.html" %}
+   {% endif %}
+   ```
+
+3. Testing Setup
+   - Create test cases for model integration
+   - Verify UI functionality
+   - Test version control operations
 
 ## Active Issues
-None at present, awaiting testing phase to identify any issues.
+1. Need to ensure consistent version control behavior across models
+2. Must handle relationships between versioned models
+3. Need to implement proper cleanup for old versions
 
-## Recent Decisions
+## Technical Dependencies
-- Used GenericForeignKey for flexible history tracking
+- django-simple-history: Base history tracking
-- Implemented HTMX for real-time updates
+- HTMX: UI interactions
-- Structured change tracking with atomic changesets
+- Alpine.js: Frontend reactivity
-- Integrated with django-simple-history
+- Custom VCS components
 
-## Technical Debt
+## Integration Strategy
-- Need comprehensive test suite
+1. Roll out model integration one app at a time
-- Performance monitoring to be implemented
+2. Update templates to include version control UI
-- Documentation needs to be expanded
+3. Add list view version indicators
+4. Implement relationship handling
+
+## Monitoring Points
+- Track version control operation performance
+- Monitor database size with version history
+- Watch for merge conflicts
+- Track user interaction patterns
+
+## Code Standards
+- All versioned models inherit from HistoricalModel
+- Consistent save method implementation
+- Proper branch context management
+- Standard version control UI components
+
+## Documentation Status
+- [x] Technical implementation
+- [x] Template integration guide
+- [ ] API documentation
+- [ ] User guide
+- [ ] Admin documentation

+# ThrillWiki Version Control System
+
+## Overview
+The ThrillWiki Version Control System (VCS) provides comprehensive version tracking, branching, and merging capabilities for all content in the system. It builds upon django-simple-history while adding powerful versioning features.
+
+## Features
+- Full version history tracking
+- Branch-based development
+- Version tagging
+- Merge operations with conflict resolution
+- Real-time collaborative editing
+- Automatic change tracking
+
+## Model Integration
+
+### Making Models Version-Controlled
+To add version control to any model, inherit from `HistoricalModel`:
+
+```python
+from history_tracking.models import HistoricalModel
+
+class YourModel(HistoricalModel):
+    # Your model fields here
+    name = models.CharField(max_length=255)
+    
+    class Meta:
+        # Your meta options
+```
+
+This automatically provides:
+- Full version history
+- Change tracking
+- Branch support
+- Merge capabilities
+
+### Example Integration (from parks/models.py)
+```python
+from history_tracking.models import HistoricalModel
+
+class Park(HistoricalModel):
+    name = models.CharField(max_length=255)
+    description = models.TextField()
+    
+    def save(self, *args, **kwargs):
+        # Changes will be automatically tracked
+        super().save(*args, **kwargs)
+```
+
+## Usage Guide
+
+### Basic Version Control Operations
+
+1. Creating a Branch
+```python
+from history_tracking.managers import BranchManager
+
+# Create a new feature branch
+branch_manager = BranchManager()
+feature_branch = branch_manager.create_branch(
+    name="feature/new-park-details",
+    user=request.user
+)
+```
+
+2. Recording Changes
+```python
+from history_tracking.signals import ChangesetContextManager
+
+# Making changes in a specific branch
+with ChangesetContextManager(branch=feature_branch, user=request.user):
+    park = Park.objects.get(id=1)
+    park.description = "Updated description"
+    park.save()  # Change is automatically tracked in the branch
+```
+
+3. Merging Changes
+```python
+# Merge feature branch back to main
+success, conflicts = branch_manager.merge_branches(
+    source=feature_branch,
+    target=main_branch,
+    user=request.user
+)
+
+if not success:
+    # Handle merge conflicts
+    for conflict in conflicts:
+        # Resolve conflicts through UI or programmatically
+        pass
+```
+
+4. Working with Tags
+```python
+from history_tracking.models import VersionTag
+
+# Tag a specific version
+VersionTag.objects.create(
+    name="v1.0.0",
+    branch=main_branch,
+    content_type=ContentType.objects.get_for_model(park),
+    object_id=park.id,
+    created_by=user
+)
+```
+
+## UI Integration
+
+### HTMX Components
+The system provides HTMX-powered components for real-time version control:
+
+1. Version Control Panel
+```html
+{% include "history_tracking/version_control_panel.html" %}
+```
+
+2. Branch Selection
+```html
+<div hx-get="{% url 'history:branch-list' %}"
+     hx-trigger="load, branch-updated from:body">
+</div>
+```
+
+3. Change History
+```html
+<div hx-get="{% url 'history:history-view' %}?branch={{ branch.name }}"
+     hx-trigger="load, branch-selected from:body">
+</div>
+```
+
+## Best Practices
+
+1. Branch Management
+- Create feature branches for significant changes
+- Use descriptive branch names (e.g., "feature/new-park-system")
+- Clean up merged branches
+- Regularly sync with main branch
+
+2. Change Tracking
+- Make atomic, related changes
+- Provide clear change descriptions
+- Group related changes in a single changeset
+- Review changes before merging
+
+3. Conflict Resolution
+- Resolve conflicts promptly
+- Communicate with team members about overlapping changes
+- Test after resolving conflicts
+- Document resolution decisions
+
+4. Performance
+- Use changesets for bulk operations
+- Index frequently queried fields
+- Clean up old branches and tags
+- Monitor system performance
+
+## Error Handling
+
+1. Common Issues
+```python
+try:
+    branch_manager.merge_branches(source, target)
+except ValidationError as e:
+    # Handle validation errors
+except MergeConflict as e:
+    # Handle merge conflicts
+```
+
+2. Conflict Resolution
+```python
+from history_tracking.utils import resolve_conflicts
+
+resolved = resolve_conflicts(
+    source_branch=source,
+    target_branch=target,
+    resolutions={
+        'conflict_id': 'resolution_type',  # 'source', 'target', or 'manual'
+    },
+    manual_resolutions={
+        'conflict_id': 'manual resolution content'
+    },
+    user=request.user
+)
+```
+
+## System Maintenance
+
+1. Regular Tasks
+- Clean up old branches
+- Archive old versions
+- Verify data integrity
+- Monitor system health
+
+2. Monitoring
+```python
+from history_tracking.utils import get_system_metrics
+
+metrics = get_system_metrics()
+# Check branch counts, merge success rates, etc.
+```
+
+## Security Considerations
+
+1. Access Control
+- All VCS operations require authentication
+- Branch operations are logged
+- Merge operations require proper permissions
+- Changes are tracked with user attribution
+
+2. Data Protection
+- Historical data is preserved
+- Audit logs are maintained
+- Sensitive data is handled securely
+- Backups include version history
+
+## Support and Troubleshooting
+
+For issues or questions:
+1. Check the logs for detailed error messages
+2. Review the conflict resolution documentation
+3. Verify branch and change permissions
+4. Contact the development team for assistance
+
+## Contributing
+When contributing to the VCS:
+1. Follow the established branching pattern
+2. Document significant changes
+3. Add tests for new features
+4. Update technical documentation

+### Detail Templates
+For detail templates, add the version control UI below the main title:
+
+```html
+<!-- Title Section -->
+<h1>{{ object.name }}</h1>
+
+<!-- Version Control UI -->
+{% include "history_tracking/includes/version_control_ui.html" %}
+
+<!-- Rest of the content -->
+```
+
+### List Templates
+For list templates, add version indicators in the list items:
+
+```html
+{% for item in object_list %}
+<div class="item">
+    <h2>{{ item.name }}</h2>
+    {% if version_control.vcs_enabled %}
+    <div class="version-info text-sm text-gray-600">
+        Branch: {{ item.get_version_info.current_branch.name }}
+    </div>
+    {% endif %}
+</div>
+{% endfor %}
+```
+
+## Integration Steps

+# Version Control System UI Improvements
+
+## Recent Improvements
+
+### 1. Template Structure Enhancement
+- Moved map initialization to dedicated JavaScript file
+- Implemented data attribute pattern for passing data to JavaScript
+- Improved template organization and maintainability
+
+### 2. JavaScript Organization
+- Created separate `map-init.js` for map functionality
+- Established pattern for external JavaScript files
+- Improved error handling and script loading
+
+### 3. Asset Management
+```javascript
+// Static Asset Organization
+/static/
+  /js/
+    version-control.js  // Core VCS functionality
+    map-init.js        // Map initialization logic
+  /css/
+    version-control.css // VCS styles
+```
+
+## Best Practices Established
+
+### 1. Data Passing Pattern
+```html
+<!-- Using data attributes for JavaScript configuration -->
+<div id="map" 
+     data-lat="{{ coordinates.lat }}"
+     data-lng="{{ coordinates.lng }}"
+     data-name="{{ name }}">
+</div>
+```
+
+### 2. JavaScript Separation
+```javascript
+// Modular JavaScript organization
+document.addEventListener('DOMContentLoaded', function() {
+    // Initialize components
+    const mapContainer = document.getElementById('map');
+    if (mapContainer) {
+        // Component-specific logic
+    }
+});
+```
+
+### 3. Template Structure
+```html
+{% block content %}
+  <!-- Main content -->
+{% endblock %}
+
+{% block extra_js %}
+  {{ block.super }}
+  <!-- Component-specific scripts -->
+  <script src="{% static 'js/component-script.js' %}"></script>
+{% endblock %}
+```
+
+## Integration Guidelines
+
+### 1. Adding New Components
+1. Create dedicated JavaScript file in `/static/js/`
+2. Use data attributes for configuration
+3. Follow established loading pattern
+4. Update base template if needed
+
+### 2. Version Control UI
+1. Include version control UI component
+2. Add necessary data attributes
+3. Ensure proper script loading
+4. Follow established patterns
+
+### 3. Static Asset Management
+1. Keep JavaScript files modular
+2. Use proper static file organization
+3. Follow naming conventions
+4. Maintain clear dependencies
+
+## Next Steps
+
+1. Apply this pattern to other templates:
+   - Ride detail template
+   - Review detail template
+   - Company detail template
+
+2. Implement consistent error handling:
+   ```javascript
+   function handleError(error) {
+       console.error('Component error:', error);
+       // Handle error appropriately
+   }
+   ```
+
+3. Add performance monitoring:
+   ```javascript
+   // Add timing measurements
+   const startTime = performance.now();
+   // Component initialization
+   const endTime = performance.now();
+   console.debug(`Component initialized in ${endTime - startTime}ms`);
+   ```
+
+4. Documentation updates:
+   - Add JavaScript patterns to technical guide
+   - Update template integration guide
+   - Document asset organization
