-        ### 1. Transfer Files to Raspberry Pi

+        if: github.ref == 'refs/heads/main'
+        run: |
+          TAG="v${{ github.run_number }}"
+          API_URL="${{ github.server_url }}/api/v1"
+          REPO="${{ github.repository }}"
 
-        **Option 1: Using SCP from your computer**
+          # Create release
+          RELEASE_ID=$(curl -s -X POST \
+            -H "Authorization: token ${{ secrets.GITEA_TOKEN }}" \
+            -H "Content-Type: application/json" \
+            "${API_URL}/repos/${REPO}/releases" \
+            -d "{\"tag_name\": \"${TAG}\", \"name\": \"Release ${TAG}\", \"draft\": false, \"prerelease\": false}" \
+            | grep -o '"id":[0-9]*' | head -1 | cut -d: -f2)
 
-        ```bash
-        # Replace with your Pi's IP address
-        PI_IP=192.168.1.100
+          # Upload asset
+          curl -s -X POST \
+            -H "Authorization: token ${{ secrets.GITEA_TOKEN }}" \
+            "${API_URL}/repos/${REPO}/releases/${RELEASE_ID}/assets?name=wol-server.tar.gz" \
+            -F "attachment=@wol-server.tar.gz" > /dev/null
 
-        # Transfer the installation package
-        scp wol-server.tar.gz pi@$PI_IP:~/
-        ```
-
-        **Option 2: Using SFTP client**
-
-        Use a tool like FileZilla, WinSCP, or Cyberduck to transfer the `wol-server.tar.gz` file to your Raspberry Pi.
-
-        ### 2. SSH into your Raspberry Pi
-
-        ```bash
-        ssh pi@192.168.1.100
-        ```
-
-        ### 3. Extract and Install
-
-        ```bash
-        # Navigate to home directory
-        cd ~
-
-        # Extract the archive
-        tar -xzf wol-server.tar.gz
-
-        # Run the installation script
-        ./install.sh
-        ```
-
-        ### 4. Test the Installation
-
-        Open a web browser and navigate to:
-        ```
-        http://[your-pi-ip]:8080
-        ```
-
-        ## Troubleshooting
-
-        If the service fails to start, check the logs:
-        ```bash
-        sudo systemctl status wol-server
-        ```
-
-        If template errors occur, ensure the template files were copied correctly:
-        ```bash
-        ls -la ~/wol-server/templates/
-        ```
-
-        ## Manual Installation (if needed)
-
-        If you encounter issues with the automated install:
-
-        ```bash
-        # Create directories
-        mkdir -p ~/wol-server/templates
-
-        # Copy files manually
-        cp wol-server-arm6 ~/wol-server/wol-server
-        chmod +x ~/wol-server/wol-server
-        cp templates/* ~/wol-server/templates/
-        sudo cp wol-server.service /etc/systemd/system/
-
-        # Install dependencies
-        sudo apt-get update
-        sudo apt-get install -y wakeonlan sshpass
-
-        # Enable and start service
-        sudo systemctl daemon-reload
-        sudo systemctl enable wol-server
-        sudo systemctl start wol-server

 - **Simple Web Interface**: Boot and shut down your server with a clean, responsive UI
-- **Status Monitoring**: Check if your target device is online
+- **Status Monitoring**: Check if your target device is online with auto-refreshing UI
+- **Scheduled Backup Window**: Configure automatic daily, bi-daily, weekly, or monthly server startup and shutdown for backup operations
+- **Auto Shutdown**: Shut down the server automatically at the end of the backup window
+- **Smart Shutdown Protection**: Only auto-shuts down servers that were started by the scheduler
+- **Passwordless Operation**: Uses environment variable for all shutdown operations
+- **Multiple Shutdown Methods**: Supports various SSH authentication methods for reliable automatic shutdown
 - **Raspberry Pi Optimized**: Built specifically for ARM processors found in all Raspberry Pi models
 - **Secure Shutdown**: Password-protected shutdown functionality
 - **Lightweight**: Minimal resource usage ideal for running on even the oldest Pi models

 - **Status Checking**: The interface shows the current status (Online/Offline)
 - **Booting**: Click the "Boot" button to send a WOL magic packet
 - **Shutting Down**: Click "Shutdown" and enter your SSH password when prompted
+- **Scheduled Backup Window**: Configure automatic server startup and shutdown on a regular schedule
+
+#### Using Scheduled Backup Window
+
+1. Click "Configure Schedule" in the Scheduled Backup Window section
+2. Enter your desired start and end times (in 24-hour format)
+3. Select a frequency (daily, every 2 days, weekly, or monthly)
+4. Optionally, enable "Auto Shutdown" (requires SHUTDOWN_PASSWORD in .env file)
+5. Click "Save Schedule" to activate
+6. The server will automatically boot at the start time and:
+   - If auto shutdown is enabled: automatically shut down at the end time
+   - If auto shutdown is disabled: remain on until manually shut down
+7. To modify an existing schedule, click "Edit Schedule"
+8. To disable, click "Disable Schedule" from the main interface
+
+**Note:** All shutdown operations (manual and scheduled) use the SHUTDOWN_PASSWORD from your .env file.
+
+#### Auto Shutdown Feature
+
+The auto shutdown feature provides several advantages:
+- Saves power by ensuring the server only runs during scheduled backup periods
+- Prevents the server from accidentally remaining on after backups are complete
+- Fully automates the backup window process
+- Smart protection: only shuts down servers that were started by the scheduler
+
+**Requirements for Shutdown Operations:**
+1. Set the `SHUTDOWN_PASSWORD` in your .env file
+2. The SSH server must be properly configured on the target server
+3. The user account specified in the configuration must have sudo privileges
+4. The password must be correct for the specified user account
+5. The server must allow password authentication via SSH
+
+**Troubleshooting Shutdown Operations:**
+- If shutdown fails, check the logs for specific error messages
+- Ensure `sshpass` is installed on your Raspberry Pi (`sudo apt-get install sshpass`)
+- Verify you can manually SSH to the server with the provided credentials
+- Confirm the user has sudo privileges to run the shutdown command
+- Check if the server requires SSH key authentication instead of password
+- Verify the SHUTDOWN_PASSWORD is correctly set in your .env file
+
+#### Auto-Refreshing UI
+
+The web interface automatically refreshes every minute (or according to the REFRESH_INTERVAL setting) to show the current server status. This ensures you always see up-to-date information without having to manually refresh the page.
