LangChain Documentation

LangChain Documentation is the official knowledge center at docs.langchain.com that teaches developers how to install, configure, and scale the LangChain framework. It combines narrative guides, API references, and ready-to-run examples for Python and TypeScript. Key sections include Quickstart (build a Retrieval-Augmented Generation chatbot in minutes), Modules (loaders, embeds, chains, agents, memory, callbacks), and a Cookbook of end-to-end notebooks covering multi-agent workflows, function invocation, and flow dashboards. Version selectors clarify breaking changes in weekly releases, while Disqus threads and “Edit on GitHub” links encourage community fixes that are automatically deployed via CI. Code snippets follow PEP 8 and TS lint guidelines, and each page references related concepts so readers can jump from loaders to vector stores without losing context. By combining clear tutorials with copy-paste code, LangChain Documentation reduces onboarding time, promotes best practices, and solidifies compliance audits for LLM production applications.
