-### **Dependencies**
+## About
+Cortex is an openAI-compatible local AI server that developers can use to build LLM apps. It is packaged with a Docker-inspired command-line interface and a Typescript client library. It can be used as a standalone server, or imported as a library. 
+
+Cortex currently supports two inference engines:
+
+- Llama.cpp
+- TensorRT-LLM
