+
+## KEY FEATURES IMPLEMENTED
+
+### 1. Universal Content Model
+- All content types use the same `Content` model
+- `entity_type` field distinguishes content types
+- `json_blocks` stores structured content (features, specifications, categories, etc.)
+- `structure_data` stores metadata (product_type, price_range, taxonomy_type, etc.)
+
+### 2. Type-Specific Prompts
+- Product prompts focus on features, specifications, pricing, benefits
+- Service prompts focus on benefits, process, pricing, FAQ
+- Taxonomy prompts focus on categories, tags, hierarchy organization
+
+### 3. Enhanced Linking
+- **Product Linking**: Links to related products (same type), related services
+- **Taxonomy Linking**: Links to related taxonomies, content within categories
+
+### 4. Enhanced Optimization
+- **Product Optimization**: Includes `product_completeness` score (pricing, features, specs)
+- **Taxonomy Optimization**: Includes `taxonomy_organization` score (categories, tags, hierarchy)
+
+### 5. API Endpoints
+- All three content types have dedicated generation endpoints
+- Consistent request/response format
+- Proper error handling and validation
