langchain-tutorials

Why we included this project

This repository pairs with a long-running YouTube tutorial series, so it works best as a hands-on companion for people learning LangChain rather than a library you drop into a project. Each notebook walks through a concrete scenario, from building chains to adding memory, retrieval, and tool-using agents, and you can run them in your own environment and adapt the patterns to your own work. The real value is the worked examples plus the explanations around them, which helps when you're moving past framework documentation and wiring up your first actual application. Since the notebooks are versioned against specific LangChain releases, they also show how the API has evolved, so you can tell which syntax matches the version you're running.
