         This guide explains how to configure Google Coral TPU support for LXC containers in Proxmox VE using <strong>ProxMenux</strong>.
         Coral TPU provides dedicated AI acceleration, improving inference performance for machine learning applications. It is particularly useful for video surveillance applications with real-time video analysis, such as <a href='https://frigate.video/' target='_blank' className='text-blue-600 hover:underline'>Frigate</a> or <a href='https://www.ispyconnect.com' target='_blank' className='text-blue-600 hover:underline'>Agent DVR</a> or <a href='https://blueirissoftware.com/' target='_blank' className='text-blue-600 hover:underline'>Blue Iris</a> using <a href='https://www.codeproject.com/ai/index.aspx' target='_blank' className='text-blue-600 hover:underline'>CodeProject.AI</a>.

+      <p className="mb-4">The script automates the complete configuration of Coral TPU support in LXC containers, including USB and M.2 variants. It applies Proxmox-specific container settings, manages device passthrough permissions, and installs required drivers both on the host and inside the container.</p>
-      <ol className="list-decimal pl-6 space-y-2 mb-6">
+      <p className="mb-4">The USB variant uses a persistent mapping based on <code>/dev/coral</code> via <code>udev</code> rules, avoiding reliance on dynamic USB paths like <code>/dev/bus/usb/*</code>. This ensures consistent device assignment across reboots and hardware reordering.</p>
-        <li>Allows selection of an existing LXC container.</li>
