      {% comment %}
        The code below dynamically generates a sidebar nav of pages with
        `layout: page` in the front-matter. See readme for usage.

        We don't use it for this web page to better customize the layout.

      {% assign pages_list = site.pages %}
      {% for node in pages_list %}
        {% if node.title != null %}
          {% if node.layout == "page" %}
            <a class="sidebar-nav-item{% if page.url == node.url %} active{% endif %}" href="{{ site.baseurl }}{{ node.url }}">{{ node.title }}</a>
          {% endif %}
        {% endif %}
      {% endfor %}
      {% endcomment %}
