 # LLM Change Agent
 [![DOI](https://zenodo.org/badge/841604583.svg)](https://zenodo.org/doi/10.5281/zenodo.13693477)
 ## Overview
-LLM Change Agent is a command-line tool designed to interact with various large language models from different providers. It generates [KGCL commands](https://github.com/INCATools/kgcl/blob/main/src/data/examples/examples.yaml) using specified models and providers via prompts. Prompts could be GitHub issue description/comments.
+LLM Change Agent is a command-line tool designed to generate knowledge graph change language (KGCL) commands that request changes in a knowledge graph such as an ontology.
+It generates [KGCL commands](https://github.com/INCATools/kgcl/blob/main/src/data/examples/examples.yaml) using specified large language models and providers via prompts.
+The prompts can be GitHub issue description/comments or natural language text.
 
 ## Features
 - Given a prompt relevant to making ontology resource changes, the agent responds with KGCL change statements.
-- Supports OpenAI, Ollama, Anthropic and CBORG (LBNL hosted) models.
