+## Build Your ChatBot with OPEA
+
+OPEA [GenAIExamples](https://github.com/opea-project/GenAIExamples) are designed to give developers an easy entry into generative AI, featuring microservice-based samples that simplify the processes of deploying, testing, and scaling GenAI applications.
+All examples are fully compatible with Docker and Kubernetes, supporting a wide range of hardware platforms such as Gaudi, Xeon, and NVIDIA GPU, and other hardwares, ensuring flexibility and efficiency for your GenAI adoption.
+
+In this section, we deploy a GenAIExample, ChatQnA, on Amazon Web Services (AWS) in two different ways: **Docker** and **Kubernetes**.
+
+ChatQnA is a Retrieval-Augmented Generation (RAG) chatbot, which integrates the power of retrieval systems to fetch relevant, domain-specific knowledge with generative AI to produce human-like responses. ChatQnA dataflow is shown in Figure 1.
+
+RAG chatbots can address various use cases by providing highly accurate and context-aware interactions, which can be used in customer support, internal knowledge management, finance and accounting, and technical support.
