-- Lightweight and dependency-free
-- Built with System.* only
-- Simple route mapping (MapGet, MapPost, etc.)
-- ActionResultFactory for clean and zero alloc response handling
-- Simply configurable host and port
+## Project Status: Archived ⚠️
+
+This project is no longer in active development. It was built as a learning exercise to understand low-level networking, async I/O, and high-performance server architecture in C#.
+
+**What was achieved:**
+
+- Custom HTTP/1.1 server implementation without using `System.Net.Http`
+- 28,000+ requests per second on commodity hardware
+- Building concurrent lock-free systems using `ThreadPool`, concurrent collections and `Interlocked`
+- Efficient parsing and response building using `Span<T>` and `Memory<T>` to minimize allocations
+- Applying YAGNI principle: writing only code I needed, when I needed it
+- Open-source development practices: MIT license, contribution guidelines, XML code documentation
+
+**Why archived:**
+I'm shifting focus to production-ready backend development (SQL, EF Core, REST APIs, microservices). This project taught me invaluable lessons about systems programming, but it's time to apply those skills to real-world backend work.
+
+The code remains here as a reference and portfolio piece. I may return to add System.IO.Pipelines and HTTP keep-alive support in the future, but for now, it's feature-complete for its original learning goals.
+
+**Key learnings:**
+- How HTTP servers actually work under the hood
+- Performance optimization and profiling techniques
+- Lock-free concurrent data structures
+- The value of knowing when NOT to over-optimize
+
+Feel free to explore the code or reach out if you have questions!
