-* Fresh Raspberry Pi OS Lite installation (recommended)
+* Supported systems:
+  - Raspberry Pi with Raspberry Pi OS
+  - Intel Mac Mini with Ubuntu Server
+  - Other x86_64 systems with Ubuntu
 * Docker installed (for running setup)
 * Internet connection for package installation
 * Target URL to display

 INSTALLATION
 ------------
 1. Configure your settings in the service configuration
-2. Run: ./install.sh
+2. Run: ./install.sh (will auto-detect system type)
 3. Confirm system modifications when prompted
 4. REBOOT the system: sudo reboot
 5. System will auto-start in kiosk mode

+The installer will automatically detect if you're running on:
+- Raspberry Pi (ARM-based)
+- Ubuntu on x86_64 (Mac Mini or PC)
+If detection fails, you'll be prompted to select manually.
+
 The installation uses a privileged Docker container to make the
 necessary system changes. This is intentional and required.
