// Translation files
template/content/texts.toml
├── [en] - English translations
└── [es] - Spanish translations

// Usage in components
let i18n = use_i18n();
let title = i18n.t("admin.content.title"); // Auto-localized
```

### **Language Detection & Storage**

```yaml
# YAML Frontmatter in content files
---
title: "Artículo de Ejemplo"
language: "es"
metadata:
  language: "es"
  reading_time: "3 minutos"
---
```

### **Database Schema**

```sql
-- Content table includes language field
CREATE TABLE content (
    id UUID PRIMARY KEY,
    title VARCHAR NOT NULL,
    language VARCHAR(2) DEFAULT 'en',
    content_type VARCHAR NOT NULL,
    state VARCHAR NOT NULL,
    -- ... other fields
);
```

## 🎨 **Visual Language Indicators**

├── English (Inglés) 🇺🇸
└── Spanish (Español) 🇪🇸
```

## 📈 **Content Statistics**

### **Bilingual Analytics**

The admin dashboard shows statistics for both languages:

```
Content Stats:
├── Total Content: 9 items
├── Published: 6 items (3 EN + 3 ES)
├── Drafts: 1 item
├── Scheduled: 1 item (ES)
└── Archived: 1 item (ES)

Top Categories:
├── General: 2 items (1 EN + 1 ES)
├── Documentation: 1 item (EN)
├── Documentación: 1 item (ES)
└── Tutorials/Tutoriales: 2 items (1 EN + 1 ES)
```

## 🚀 **Usage Examples**

### **Admin Interface Language Switching**

Users can switch interface language using the language selector:

```typescript
// Language switching in UI
<LanguageSelector />
// or
<LanguageToggle />
```

### **Content Creation Workflow**

1. **Create English Content**
   - Set language to "en"
   - Fill English metadata
   - Use English tags and categories

2. **Create Spanish Version**
   - Set language to "es" 
   - Translate title and content
   - Use Spanish tags and categories
   - Link to English version (optional)

### **Content Management**

```bash
# Filter by language
GET /admin/content?language=es

# Search in specific language
GET /admin/content?search=guía&language=es

# Create bilingual content
POST /admin/content
{
  "title": "Mi Artículo",
  "language": "es",
  "tags": ["español", "ejemplo"]
}
```

## 🔄 **Migration Path**

### **Adding More Languages**

1. **Add translations** to `texts.toml`:
   ```toml
   [fr]
   "admin.content.title" = "Gestion de Contenu"
   ```

2. **Update language enum**:
   ```rust
   enum Language {
       English,
       Spanish,
       French, // Add new language
   }
   ```

3. **Add content examples** in new language

### **Extending Content Types**

Easy to add new content types with full i18n support:

```toml
[en]
"admin.content.type.newsletter" = "Newsletter"

[es]
"admin.content.type.newsletter" = "Boletín"
```

## 🏆 **Best Practices**

### **Content Creation**

1. **Consistent Slugs** - Use language-specific slugs
   - English: `getting-started-guide`
   - Spanish: `guia-de-inicio`

2. **Language-Specific Categories**

   - Spanish: "Documentación"

3. **Appropriate Tags**

4. **SEO Optimization**
