```

#### Content Management System

##### Documentation Integration
The help system integrates existing documentation through a structured content management approach:

**Resource Packaging**:
- Convert existing `.md` files to embedded Python resources
- Maintain parallel English/French content structure
- Implement automatic fallback to English for missing French content
- Version synchronization with application releases

**Content Organization**:
```python
help_content_structure = {
    "quick_start": {
        "en": "Quick Start (5 minutes)",
        "fr": "Démarrage Rapide (5 minutes)",
        "icon": "🚀",
        "source": "QUICK_START.md"
    },
    "campaign_setup": {
        "en": "Campaign Setup",
        "fr": "Configuration de Campagne", 
        "icon": "📁",
        "source": "USER_GUIDE.md#campaign-setup"
    },
    "smtp_config": {
        "en": "Email Configuration",
        "fr": "Configuration Email",
        "icon": "📧", 
        "source": "DOCUMENTATION_EN.md#smtp-setup"
    }
}
```

##### Dynamic Content Loading
- **Lazy Loading**: Load content sections on-demand for performance
- **Markdown Processing**: Convert markdown to rich HTML with syntax highlighting
- **Cross-References**: Implement internal linking between help sections

**Search Implementation**:
```python
class HelpSearchSystem:
    def __init__(self):
        self.search_index = self.build_search_index()
    
    def search(self, query: str, language: str) -> List[SearchResult]:
        """Perform full-text search across help content"""
        results = []
        for section, content in self.search_index[language].items():
            matches = self.find_matches(query, content)
            if matches:
                results.append(SearchResult(section, matches))
        return sorted(results, key=lambda x: x.relevance_score)
```

```python
class HelpContentManager:
    """Manage help content resources and caching"""
    
    def __init__(self):
        self.content_cache = {}
        self.resource_base = "gui/help"
    
    def load_content(self, section: str, language: str) -> str:
        """Load help content with caching"""
        cache_key = f"{section}_{language}"
        
        if cache_key not in self.content_cache:
            resource_path = f"{self.resource_base}/{language}/{section}.md"
            try:
                content = pkgutil.get_data(__package__, resource_path)
                if content:
                    self.content_cache[cache_key] = content.decode('utf-8')
                else:
                    # Fallback to English if French not available
                    if language == 'fr':
                        return self.load_content(section, 'en')
                    raise FileNotFoundError(f"Help content not found: {resource_path}")
            except Exception as e:
                return self.get_error_content(section, str(e))
        
        return self.content_cache[cache_key]
```
