Build a local RAG chatbot on your own documents

This guide details how to build a local Retrieval-Augmented Generation (RAG) chatbot using Python, Ollama, and ChromaDB. The project allows users to query their own documents without needing API keys or cloud services, running entirely on a laptop with as little as 8GB of RAM. Key steps involve setting up the necessary software, loading and chunking documents, embedding these chunks into vectors using `nomic-embed-text`, storing them in ChromaDB, and then querying the system with `llama3.2` while providing relevant context to minimize hallucinations.
