        <h3>Usage</h3>
        <ol>
          <li>Drag the following buttons and drop them into your bookmarks. They are so called <a href="https://en.wikipedia.org/wiki/Bookmarklet">bookmarklets</a>. </li>
          <li>Open site you want to backup / restore and click on this bookmarked button.</li>
        </ol>

        <h3>Backup</h3>
        <p>
          Takes all key-value pairs from your local storage and serves them to download as a JSON file.
        </p>
        <a class="btn" href="#" data-function="localStorageBackup">Backup local storage</a>

        <h3>Restore</h3>
        <p>
          Creates overlay in current page with one file selector. Select file with backups. All items will be automatically restored.
        </p>
        <a class="btn" data-function="localStorageRestore" href="#">Restore local storage</a>

        <h3>Clear</h3>
        <p>
          Removes all items from local storage.
        </p>
        <a class="btn" data-function="localStorageClear" href="#">Clear local storage</a>

        <h3>Security, privacy</h3>
        <p>All operations are executed locally. There is no server side, no tracking, no server uploads.
          HTML5 provides necessary functionality like <a href="https://developer.mozilla.org/en-US/docs/Web/API/FileReader">File API</a>.
          You can always examine the source code of bookmarklets and the <a href="https://github.com/todvora/localstorage-backup">repository itself</a>.</p>
        <h3>Limitations</h3>
        <a href="https://en.wikipedia.org/wiki/Content_Security_Policy">Content-Security-Policy</a> can block execution of script stored as a <a href="https://en.wikipedia.org/wiki/Bookmarklet">bookmarklet</a>. in this case backup and restore doesn't work.
