Build a chatbot to query your documentation using Langchain and Azure OpenAI

LangChain is a Python library for building NLP applications using large language models. It simplifies tasks like prompt management, chaining calls, data augmentation, and memory persistence. The library supports various language models and provides tools for document loading and vector database storage. An example application is demonstrated, where a question-answering tool is built using Azure Functions documentation and LangChain's capabilities.
