+### Detection Methods Implemented
+- ✅ NuGet package analysis (primary method)
+- ✅ Project SDK attribute detection
+- ✅ Multi-targeting detection
+- ✅ Project file property analysis
+- ⚠️ Using statements (not yet implemented - future enhancement)
+- ⚠️ Base classes (not yet implemented - future enhancement)
+- ⚠️ Attributes (not yet implemented - future enhancement)
+
+### Architecture
+- **Extensible plugin system** - Each category has its own detector class implementing `IFrameworkFeatureDetector`
+- **Single Responsibility** - Easy to add new detectors without modifying existing code
+- **Testable** - 35+ unit tests covering detection logic
+- **Ordered output** - Categories appear in logical order (Web → Data → Auth → Cloud → Logging → Testing)
+
+### Output Format
+Framework features are displayed in categorized tables showing:
+- Feature name
+- Package providing the feature
+- Version
+- Projects using the feature
+
+### Additional Features to Implement
+
+#### **High Priority**
+- **Background Processing Detection**
+  - Hangfire
+  - Quartz.NET
+  - MassTransit
+  - Rebus
+  - IHostedService implementations
+
+- **Serialization & API Technologies**
+  - System.Text.Json (built-in detection)
+  - Newtonsoft.Json (legacy detection)
+  - Protobuf
+  - MessagePack
+
+- **Dependency Injection Extensions**
+  - Autofac
+  - Scrutor
+  - Custom DI containers
+
+#### **Medium Priority**
+- **HTTP Client & API Communication**
+  - HttpClient patterns
+  - Refit
+  - RestSharp
+  - Polly (resilience patterns)
+
+- **Caching**
+  - In-memory caching
+  - Distributed caching
+  - Output caching
+
+- **Real-time & Messaging**
+  - Event buses
+  - Message brokers
+  - Pub/sub patterns
+
+#### **Source Code Analysis (Future Enhancement)**
+To detect frameworks used without explicit package references:
+- ASP.NET Core Minimal APIs (using statements, endpoint mapping patterns)
+- BackgroundService implementations (base class detection)
+- Controller/Hub inheritance patterns
+- Custom attributes and middleware
 
 ### Value  
-- Helps teams understand architectural patterns  
-- Supports modernization and migration planning  
-- Enables feature‑level compliance checks  
+- ✅ Provides instant visibility into architectural patterns in use
+- ✅ Supports modernization and migration planning (e.g., Newtonsoft.Json → System.Text.Json)
+- ✅ Enables feature‑level compliance checks
+- ✅ Helps new team members understand the tech stack
+- ✅ Identifies technology sprawl and opportunities for consolidation
