-# EnggSS RAG ChatBot
-
-**Serving-only** HuggingFace Space — reads a pre-built private dataset, no PDF
-processing at runtime.  Build the dataset locally with
-`preprocessing/create_dataset.py`, then deploy this Space to answer questions.
-
-## How it works
-
-```
-Local machine (once)
-  PDFs  →  create_dataset.py  →  BAAI/bge-large-en-v1.5 embeddings
-                                        │
-                                        ▼
-                            Private HuggingFace Dataset
-                                        │
-                  ┌─────────────────────┘
-                  ▼  (Space startup)
-         Load dataset → NumPy float32 matrix (L2-normalised)
-                  │
-                  ▼  (each query, ~20 ms)
-         Embed query → cosine scores → MMR top-3
-                  │
-                  ▼
-         Qwen2.5-7B-Instruct (HF Inference API) → answer
-                  │
-                  ▼
-              Gradio UI

-## Tabs
-
-| Tab | Purpose |
-|-----|---------|
-| 💬 Q&A | Ask questions; see top-3 retrieved contexts + generated answer |
-| 📊 Analytics | Total chunks, documents processed, per-file breakdown |
-
-## Required Space Secrets
-
-Set in **Settings → Variables and Secrets**:
-
-| Secret | Description |
-|--------|-------------|
-| `HF_TOKEN` | HuggingFace token — needs **read** access to the dataset repo |
-| `HF_DATASET_REPO` | e.g. `your-org/enggss-rag-dataset` (created by preprocessing script) |
-
-## Setup order
-
-1. **Run preprocessing locally** (once, or when you add new PDFs):
-   ```bash
-   cd preprocessing
-   pip install -r requirements.txt
-   python create_dataset.py ./pdfs --repo your-org/enggss-rag-dataset
-   ```
-2. **Deploy this Space** — upload `app.py` + `requirements.txt` + `README.md`
-3. **Set the two secrets** above in Space Settings → Secrets
-4. Space restarts, loads the dataset, and is ready to answer questions
-
-To add new PDFs later without rebuilding everything:
-```bash
-python create_dataset.py ./pdfs --repo your-org/enggss-rag-dataset --update
-```
-
-## Local development
-
-```bash
-git clone https://huggingface.co/spaces/your-org/enggss-rag-chatbot
-cd enggss-rag-chatbot
-pip install -r requirements.txt
-# create .env with HF_TOKEN and HF_DATASET_REPO
-python app.py
-```
