-## Overview
+## Quick Install
+
+```bash
+pip install "langchain[model-profiles]"
+```
+
+## 🤔 What is this?
 
 `langchain-model-profiles` enables programmatic access to model capabilities through a `.profile` property on LangChain chat models.
 
 This allows you to query model-specific features such as context window sizes, supported input/output modalities, structured output support, tool calling capabilities, and more.

 ## Data sources
 
 This package is built on top of the excellent work by the [models.dev](https://github.com/sst/models.dev) project, an open source initiative that provides model capability data.
 
 This package augments the data from models.dev with some additional fields. We intend to keep this aligned with the upstream project as it evolves.
