        <p>Creating redirects:</p>
        <ul>
          <li>Click the green "Add new redirect" button.</li>
          <li>Select a matcher type and enter what it should match on.</li>
          <li>
            Select a redirect type and enter where you want to be redirected.
          </li>
          <li>
            See the "Matchers" and "Redirects" sections below for lists of
            everything available with examples.
          </li>
        </ul>

        <p>Using redirects:</p>
        <ul>
          <li>
            Any time you are navigated to a link by your browser, the URL will
            first be checked and you will be redirected automatically.
          </li>
        </ul>

        <p>Editing redirects:</p>
        <ul>
          <li>
            If a redirect has been edited, a yellow border will be shown around
            it.
          </li>
          <li>
            Changes to redirects are only saved when you click the save button.
          </li>
          <li>
            To enable or disable a redirect, click the button with the circle.
            If it's filled in the redirect is enabled.
          </li>
          <li>To remove a redirect click the red button with the ✗ twice.</li>
        </ul>

        <p>Some miscellaneous notes:</p>
        <ul>
          <li>Only URLs starting with "http" will be checked.</li>
          <li>
            Navigation events won't be checked if it has been less than 100
            milliseconds since the last successful redirect.
          </li>
          <li>
            A redirect will be cancelled if the exact same redirect happened
            less than 30 seconds ago. This acts as a quick bypass so you don't
            have to disable redirects in the options page whenever you don't
            want to be redirected.
          </li>
        </ul>

        <p>As a quick-start you can also insert the examples from below:</p>
        <ul>
          <li>
            Note that this will reload the page so make sure your redirects have
            been saved.
          </li>
          <li>
            <button class="button" onClick=${window.Holllo.insertExamples}>
              Insert Examples
            </button>
          </li>
