 # Databricks AI Bridge library
 
-The Databricks AI Bridge library provides a shared layer of APIs to interact with Databricks AI features, such as [Databricks AI/BI Genie ](https://www.databricks.com/product/ai-bi/genie) and [Vector Search](https://docs.databricks.com/en/generative-ai/vector-search.html).
+The Databricks AI Bridge library provides a shared layer of APIs to interact with Databricks AI features, such as [Databricks AI/BI Genie ](https://www.databricks.com/product/ai-bi/genie) and [Vector Search](https://docs.databricks.com/en/generative-ai/vector-search.html). Use these packages to help [author agents with Agent Framework](https://docs.databricks.com/aws/en/generative-ai/agent-framework/author-agent#requirements) on Databricks.
 
-## Integrations
+## Integration Packages
 
-This library also contains the source code for the following integration packages. These integration packages provide seamless integration of Databricks AI features to use in AI authoring frameworks.
+If you are using LangChain/LangGraph or the OpenAI SDK, we provide these integration packages for seamless integration of Databricks AI features.
 
-- [`databricks-langchain`](./integrations/langchain/README.md)
-- [`databricks-openai`](./integrations/openai/README.md)
+- [`databricks-langchain`](./integrations/langchain/README.md) - For LangChain/LangGraph users
+- [`databricks-openai`](./integrations/openai/README.md) - For OpenAI SDK users
 
 ## Installation
 
-If you are using LangChain or OpenAI, you should install `databricks-langchain` or `databricks-openai`. Refer to the linked READMEs for more details. For other frameworks without dedicated integration packages, use `databricks-ai-bridge` instead.
