+# Financial RAG System
+
+This repository documents a Financial Retrieval-Augmented Generation system for answering questions over SEC 10-K and 10-Q filings.
+
+Live demo: https://huggingface.co/spaces/anasxs/financial-rag
+
+GitHub: https://github.com/Anassbzdd/financial-RAG
+
+## System Overview
+
+This is not a fine-tuned language model. It is a RAG system that combines document parsing, chunking, vector retrieval, keyword retrieval, reranking, and grounded answer generation.
+
+The system answers questions using indexed SEC filings from:
+
+- Apple
+- Amazon
+- Alphabet
+- Berkshire Hathaway
+- Johnson and Johnson
+
