      <ul className="list-disc pl-5 mb-4">
        <li>Adds the Ceph repository to your system</li>
        <li>Updates package lists</li>
        <li>Installs Ceph packages using the 'pveceph install' command</li>
        <li>Verifies the installation</li>
      </ul>
      <p className="mb-4">
        How to use: After installation, you can configure and manage Ceph storage using the Proxmox VE web interface or
        command-line tools.
      </p>
      <p className="text-lg mb-2">This adjustment automates the following commands:</p>
      <CopyableCode
        code={`
# Add Ceph repository
echo "deb https://download.proxmox.com/debian/ceph-squid $(lsb_release -cs) no-subscription" > /etc/apt/sources.list.d/ceph-squid.list
