LangChain docs

The LangChain documentation is the official guides and API reference, hosted at docs.langchain.com, that are designed to help developers go from “pip install” to production-grade Large Language Model (LLM) applications. They combine narrative guides, copy-paste code, and auto-generated class docs for Python and TypeScript. Quickstart shows how to build a Retrieval-Augmented Generation chatbot in under 10 minutes; Modules dives into loaders, embeds, chains, agents, memory, and callbacks; and Cookbook offers end-to-end notebooks on orchestration, streaming, and multi-agent evaluation. Version selectors clearly display breaking changes in weekly releases, while search displays pages of code and concepts side-by-side. Each page links to Colab or Codespaces, embeds Disqus streams for Q&A, and has an “Edit on GitHub” button that feeds a CI pipeline so community fixes are deployed in minutes. By combining concise explanations with real-world examples, LangChain’s docs reduce onboarding time, instill best practices, and solidify compliance audits for enterprise AI.
