## Quick Install

`pip install langchain`

## 🤔 What is this?

Large language models (LLMs) are emerging as a transformative technology, enabling
developers to build applications that they previously could not.
But using these LLMs in isolation is often not enough to
create a truly powerful app - the real power comes when you can combine them with other sources of computation or knowledge.

This library is aimed at assisting in the development of those types of applications.

## 📖 Documentation

Please see [here](https://langchain.readthedocs.io/en/latest/?) for full documentation on:

- Getting started (installation, setting up the environment, simple examples)
- How-To examples (demos, integrations, helper functions)
- Reference (full API docs)
  Resources (high-level explanation of core concepts)

## 🚀 What can this help with?

There are four main areas that LangChain is designed to help with.
These are, in increasing order of complexity:

1. LLM and Prompts
2. Chains
3. Agents
4. Memory

For more information on these concepts, please see our [full documentation](https://langchain.readthedocs.io/en/latest/?).

Improve credential handing to allow passing in constructors (#79) Addresses the issue in #76 by either using the relevant environment variable if set or using a string passed in the constructor. Prefers the constructor string over the environment variable, which seemed like the natural choice to me. 2022-11-07 21:34:45 +00:00			[![lint](https://github.com/hwchase17/langchain/actions/workflows/lint.yml/badge.svg)](https://github.com/hwchase17/langchain/actions/workflows/lint.yml) [![test](https://github.com/hwchase17/langchain/actions/workflows/test.yml/badge.svg)](https://github.com/hwchase17/langchain/actions/workflows/test.yml) [![License: MIT](https://img.shields.io/badge/License-MIT-yellow.svg)](https://opensource.org/licenses/MIT) [![Twitter](https://img.shields.io/twitter/url/https/twitter.com/langchainai.svg?style=social&label=Follow%20%40LangChainAI)](https://twitter.com/langchainai) [![](https://dcbadge.vercel.app/api/server/6adMQxSpJS?compact=true&style=flat)](https://discord.gg/6adMQxSpJS)
