+
+## ⚡ Installation
+
+### Requirements
+- **Python 3.9+**
+- **PySide6** for GUI
+- **Windows** or **macOS** (Linux support planned)
+
+### Install dependencies
 ```bash

 ```
 
-## Usage
+For Windows registry scanning:
+```bash
+pip install pywin32
+```
+
+### Run the app
+```bash
+python SAK_Utility_Full_With_MT_LicenseScan.py
+```
+
+---
+
+## 🚀 Usage Guide
+
+1. **Set Backup Location** → Choose where backups will be stored.
+2. **Select Users** → Pick user profiles to include in backups.
+3. **Start Backups** → One-click backups for Documents, Photos, etc.
+4. **Organize Folders** → Sort files by extension automatically.
+5. **Find Duplicates** → Delete, move, or export duplicate reports.
+6. **Scan License Keys** → With admin privileges for full registry access.
+7. **Keep Screen On** → Prevents sleep during long operations.
+
+---
+
+## ⚠️ Known Issues
+
+- **License Key Limitations**: Many modern apps store keys in encrypted or cloud locations.
+- **Registry Access**: Some Windows registry keys remain inaccessible even with admin rights.
+- **macOS Plists**: Binary or encrypted plists may not reveal keys.
+- **Backup Speed**: Disk I/O limits speed on slow drives.
+- **Platform Differences**: Some features are Windows-only.
 
-1. Open a terminal and navigate to the `Windows Backup` folder.
-2. Run the script:
-   ```bash
-   python windows_backup.py
-   ```
-3. Click **Set Backup Location** and choose your backup destination.
-4. Click any of the backup buttons (e.g., "Backup Documents") to back up that folder.
+---
 
-## Notes
+## 🔮 Future Enhancements
 
-- The script uses `xcopy`, which is available on Windows systems.
-- Each backup creates a subfolder in your backup location with the same name as the source (e.g., "Documents").
-- Make sure you have permission to read the source folders and write to the backup location.
+- **Modern GUI**: Tabs, dark mode, and custom themes.
+- **Backup Scheduler**: Automate recurring backups.
+- **Cloud Integration**: Direct backups to Google Drive, OneDrive, Dropbox.
+- **Thread Control**: User-defined thread limits.
+- **Integrated Log Viewer**: Read logs inside the app.
+- **Linux Support**: Extend compatibility to Linux systems.
+- **Incremental Backups**: Copy only changed files after first backup.
