# Chapter Overview
This chapter introduces the creation, configuration, debugging and publishing methods of RAGFlow Agent. You can connect models, knowledge bases, tools and workflow control components through a visual canvas to build intelligent agent applications such as knowledge Q&A, business query, content processing and automated execution.

:::tip NOTE
Before using an Agent, please confirm that at least one available chat model has been configured. If the workflow needs to query knowledge bases, you also need to create knowledge bases in advance, upload files and complete parsing.
