LangChain Documentation

LangChain Documentation is the official knowledge center at docs.langchain.com that helps developers install, configure, and scale the LangChain framework. The site combines narrative guides, copy-paste code, and auto-generated API links for Python and TypeScript. Sections include Quickstart, which connects LLM to a vector store in under 10 minutes; Modules, which covers hints, memory, agents, and callbacks; and Cookbook, with examples of end-to-end search-augmented generation (RAG), multi-agent, and streaming. Interactive Jupyter notebooks link to Colab for one-click launches, while version selectors save breaking changes in weekly releases. Each page embeds Disqus streams and GitHub “Edit” buttons, inviting the community to contribute patches that are automatically deployed via CI. Code snippets are PEP 8 compliant, and sidebars display related concepts so readers can jump from loaders to embeds without losing context. By combining conceptual overviews with executable snippets, LangChain documentation reduces onboarding time, speeds up prototyping, and solidifies best practices for production LLM pipelines.
