Why we included this project
Most RAG tutorials stop at a demo that works only with the sample data. This one goes further, building a LangChain pipeline that ingests PDFs, embeds them into a vector store, talks to a local LLM through Ollama so nothing has to go to a cloud API, and adds new items to the database. It also includes a testing section, which is rare in tutorials and worth having if you want to check your own setup before relying on it. For readers who learn better from working code than from documentation, it's a complete end-to-end example, and teams without much RAG experience can adapt it as a reference implementation.
