-## Environment Variables
-
-Set these in **HF Spaces → Settings → Repository secrets**:
-
-| Variable | Required | Description |
-|---|---|---|
-| `GROQ_API_KEY` | ✅ | [console.groq.com](https://console.groq.com) |
-| `DEEPGRAM_API_KEY` | ✅ | [console.deepgram.com](https://console.deepgram.com) |
-| `LIVEKIT_API_KEY` | ⬜ | Reserved for future WebRTC streaming |
-
----
-
-## Deployment — HF Spaces (Gradio SDK)
-
-1. Create a new Space → **Gradio** SDK
-2. Push these files — no Dockerfile needed:
-   ```
-   app.py
-   requirements.txt
-   README.md
-   ```
-3. Add secrets under **Settings → Repository secrets**: `GROQ_API_KEY`, `DEEPGRAM_API_KEY`
-4. HF installs `requirements.txt` automatically and runs `app.py`
-
----
-
-## Knowledge Base Setup
-
-1. Open **Admin Panel** (left sidebar) after launch
-2. Upload one or more `.txt` files → click **Build KB**
-3. FAISS index is built in-memory and persisted to `faiss.index` + `chunks.npy`
-
-## Orders Database Setup
-
-1. Export your SQLite `.db` file with an `orders` table:
-   ```sql
-   CREATE TABLE orders (
-       order_id         INTEGER PRIMARY KEY,
-       order_date       TEXT,
-       customer_name    TEXT,
-       customer_city    TEXT,
-       customer_address TEXT,
-       status           TEXT,
-       delivery_date    TEXT,
-       comments         TEXT
-   );
-   ```
-2. Upload via **Admin Panel → Orders Database**
-
----
-
-## Usage Flow
-
-1. Page loads → **welcome message plays** in EN / AR / UR
-2. Say or click your **language** → Reem confirms
-3. **Speak** into mic or **type** in the text box
-4. Reem routes your query:
-   - Order number / tracking keywords → **SQL lookup**
-   - General questions → **RAG knowledge base**
-5. Response **streams** from Groq → TTS plays automatically
-6. Reem **remembers** order IDs and customer name across turns

-
-# Set env vars
-export GROQ_API_KEY=gsk_...
-export DEEPGRAM_API_KEY=...
-
-# Run

-## Differences from Streamlit Version
-
-| Aspect | Streamlit + Railway | Gradio on HF Spaces |
-|---|---|---|
-| Port management | FastAPI proxy required | Single port, native |
-| Streaming TTS | `st.components.v1.html` workaround | `gr.Audio(autoplay=True)` |
-| STT | `streamlit-mic-recorder` | `gr.Audio(sources=["microphone"])` |
-| Re-render issues | Duplicate responses on rerun | State-based, no reruns |
-| Barge-in | Manual WebSocket lifecycle | Deepgram `stop_recording` event |
