+# Quantum Healthcare Navigator ⚕️🧠🔬
 
+Welcome to the Quantum Healthcare Navigator, an AI-powered application designed for healthcare professionals. This Hugging Face Space demonstrates the integration of Large Language Models (LLMs), specialized medical information tools, and (simulated) quantum-inspired optimization for treatment suggestions.
+
+## ✨ Features
+
+*   **AI Consultation:** Interactive chat with an AI assistant.
+*   **Medical Knowledge Access:** Tools for UMLS and BioPortal lookups.
+*   **Quantum Treatment Optimizer:** (Simulated) Get suggestions for treatment plans based on patient data.
+*   **User Authentication:** Secure login and signup.
+*   **Session Management:** Chat history is saved per user session.
+*   **PDF Reports:** Download consultation transcripts.
+*   **Dockerized:** Easy to deploy and run locally.
+

+## ⚙️ Setup & Configuration
+
+1.  **Clone the repository (if applicable) or create the files as listed.**
+2.  **Create a `.env` file** in the root `quantum_healthcare_app/` directory based on `.env.example`. Populate it with your API keys and desired settings.
+    ```env
+    APP_TITLE="Quantum Healthcare Navigator"
+    SECRET_KEY="your_very_secret_key"
+
+    DATABASE_URL="sqlite:///./quantum_healthcare.db" # Default for HF Spaces
+
+    OPENAI_API_KEY="sk-..."
+    GEMINI_API_KEY="..."
+    UMLS_API_KEY="..."
+    BIOPORTAL_API_KEY="..."
+
+    LOG_LEVEL="INFO"
+    ```
+3.  **Hugging Face Space Deployment:**
+    *   Create a new Space on Hugging Face.
+    *   Choose "Docker" as the Space SDK (or Streamlit and provide `requirements.txt`). Docker is recommended for this complexity.
+    *   Upload your files.
+    *   Go to "Settings" in your Space and add your `.env` variables as **Secrets**.
+    *   The Space should build and run the `Dockerfile`.
+
+## 🚀 Running Locally (using Docker)
+
+1.  **Ensure Docker and Docker Compose are installed.**
+2.  **Create and populate your `.env` file** as described above.
+3.  **Build and run the application:**
+    ```bash
+    docker-compose up --build
+    ```
+4.  Open your browser and navigate to `http://localhost:8501`.
+
+## 📝 Notes
+
+*   The **Quantum Optimizer** is currently a stub. It simulates quantum processing but doesn't connect to actual quantum hardware.
+*   **UMLS and BioPortal API** interactions are simplified. Real integration requires more robust error handling, authentication (e.g., UMLS Ticket Granting Tickets), and result parsing.
+*   **Error handling and logging** are basic. Production systems would require more comprehensive strategies.
+*   **Security:** While basic authentication is implemented, ensure all security best practices if deploying for wider use (e.g., HTTPS, input validation, dependency scanning).
+*   This application is for **demonstration purposes only** and should not be used for actual medical decision-making.
