-# Persistent Storage Setup for Hugging Face Spaces
-
-## Overview
-This application now uses HF Spaces persistent storage to save student registration data permanently.
-
-## How It Works
-
-### Automatic Detection
-The app automatically detects if persistent storage is available:
-- **On HF Spaces with storage enabled:** Uses `/data/students.db`
-- **Locally or without storage:** Falls back to `students.db` in project directory
-
-### Code Implementation
-```python
-PERSISTENT_DIR = "/data"
-if os.path.exists(PERSISTENT_DIR) and os.access(PERSISTENT_DIR, os.W_OK):
-    DB_PATH = os.path.join(PERSISTENT_DIR, "students.db")
-    print(f"✅ Using persistent storage: {DB_PATH}")
-else:
-    DB_PATH = "students.db"
-    print("⚠️ Persistent storage not available")
-```
-
-## Enabling Persistent Storage on HF Spaces
-
-### Steps:
-1. Go to your Space: https://huggingface.co/spaces/gladguy/SimpleProject
-2. Click **Settings** (gear icon)
-3. Scroll to **Storage**
-4. Click **Enable persistent storage**
-5. Choose storage size (recommended: at least 1GB)
-6. Restart the Space
-
-### Verification
-Check the container logs after enabling storage. You should see:
-```
-✅ Using persistent storage: /data/students.db
-```
-
-## Benefits
-- ✅ **Data Persistence:** Student registrations survive Space restarts
-- ✅ **Sleep Mode Safe:** Data retained when Space goes to sleep
-- ✅ **Automatic Fallback:** Works both locally and on HF Spaces
-- ✅ **No Code Changes:** Same code works in both environments
-
-## Database Location
-- **HF Spaces (with storage):** `/data/students.db`
-- **Local development:** `./students.db`
-- **HF Spaces (without storage):** `./students.db` (ephemeral, will be wiped)
-
-## Important Notes
-- Persistent storage is a **paid feature** on HF Spaces
-- Free tier Spaces will use ephemeral storage
-- Local development always uses local `students.db`
