 ## Project Overview
 
 ModelGrid is a root-level daemon that manages GPU infrastructure, Docker, and AI model containers

 ### Greenlit Model System
 
-- Only pre-approved models can be auto-pulled for security
-- Greenlist fetched from remote URL (configurable)
+- Only catalog-listed models can be auto-deployed on demand
+- Catalog fetched from a remote URL (configurable)
 - VRAM requirements checked before loading
 
 ### Container Types
 
-- **Ollama**: Easy to use, native API converted to OpenAI format
 - **vLLM**: High performance, natively OpenAI-compatible
 - **TGI**: HuggingFace Text Generation Inference
