This hands-on guide introduces Retrieval-Augmented Generation (RAG), a practical technique for enhancing Large Language Models (LLMs) by integrating external knowledge sources. The resource covers core concepts in AI, LLMs, and RAG, and provides step-by-step examples and visual explanations to help learners build more accurate and context-aware AI systems.
The guide leverages open-source tools such as FAISS, Milvus, and LangChain, and is designed for learners with basic programming or AI familiarity who want to move beyond prompt-only approaches toward production-ready LLM applications.
