 ## Quick Start
 
+## WARNING
+This is a research tool that can be configured to execute LLM-generated code. LLM-generated code may take dangerous or unwanted actions, incuding sending private data to uncontrolled locations, deleting files, or modifying its environments.  Ensure you run NOOA agents in a sandboxed environment isolated from your primary filesystem, such as [NVIDIA OpenShell](https://github.com/NVIDIA/OpenShell).
+
+> **Research software**  NOOA is research software, not production. We welcome contributions and fixes, but expect rough edges.
