 # humanus.cpp
 
-Humanus (meaning "human" in Latin) is a lightweight framework inspired by [OpenManus](https://github.com/mannaandpoem/OpenManus) and [mem0](https://github.com/mem0ai/mem0), integrated with the Model Context Protocol (MCP). `humanus.cpp` enables more flexible tool choices, and provides a foundation for building powerful local LLM agents.
+Humanus (meaning "human" in Latin) is a **lightweight C++ framework** inspired by [OpenManus](https://github.com/mannaandpoem/OpenManus) and [mem0](https://github.com/mem0ai/mem0), integrated with the Model Context Protocol (MCP). 
+
+**Key Features:**
+- **C++ Implementation**: Core functionality written in efficient C++ for optimal performance and resource utilization
+- **Lightweight Design**: Minimalist architecture with minimal dependencies, suitable for resource-constrained environments
+- **Cross-platform Compatibility**: Full support for Unix, MacOS, and Windows systems
+- **MCP Protocol Integration**: Seamless integration with Model Context Protocol for standardized tool interactions
+- **Vectorized Memory Storage**: Efficient similarity search based on HNSW algorithm for intelligent context retrieval
+- **Modular Architecture**: Easy to extend and customize, supporting various LLM models and tool integrations
 
 Let's embrace local LLM agents **w/** humanus.cpp!
