+          **Branch:** ${{ github.ref_name }}

+          ### ISO Information
+          - **Filename:** ${{ steps.iso_info.outputs.iso_name }}
+          - **Size:** ${{ steps.iso_info.outputs.iso_size }}
+          - **SHA256:** \`${{ steps.iso_info.outputs.iso_sha256 }}\`
+          
+          ### Installation
+          1. Download the ISO file
+          2. Verify the checksum using SHA256SUMS
+          3. Write to USB using dd, Ventoy, or similar tools:
+             \`\`\`bash
+             dd if=${{ steps.iso_info.outputs.iso_name }} of=/dev/sdX bs=4M status=progress
+             \`\`\`
+          4. Boot from the USB drive
+          
+          ### Verification
+          \`\`\`bash
+          sha256sum -c SHA256SUMS
+          \`\`\`
