  <ul class="small">
    <li>While it's open, Bookkeeper looks at <strong>updates.decaro.net</strong> once a day for a new version. It only
      downloads the version number — nothing about you or your books is sent.</li>
    <li>Every update is digitally signed. Bookkeeper checks the signature and refuses anything that doesn't match.</li>
    <li>Nothing installs until you click <strong>Install</strong>.</li>
