+LangChain is a framework for developing applications powered by large language
+models (LLMs).
+
+LangChain simplifies every stage of the LLM application lifecycle:
+* Development: Build your applications using LangChain's open-source components
+ and third-party integrations. Use LangGraph to build stateful agents with
+ first-class streaming and human-in-the-loop support.
