 ### About this repo
 
-This repository provides an end-to-end solution for users who want to query their data with natural language. It includes a well designed ingestion mechanism for multiple file types, an easy deployment, and a support team for maintenance. The accelerator demonstrates both Push or Pull Ingestion; the choice of orchestration (Semantic Kernel, LangChain, OpenAI Functions or Prompt Flow) and should be the minimum components needed to implement a RAG pattern. It is not intended to be put into Production as-is without experimentation or evaluation of your data. It provides the following features:
