+Configure the sidebar
+=====================
+
+``pydata_sphinx_theme`` provides two new sidebar items by default:
+
+- ``sidebar-nav-bs.html`` - a bootstrap-friendly navigation section
+- ``sidebar-search-bs.html`` - a bootstrap-friendly search bar
+
+By default, this theme's sidebar has these two elements in it. If you'd like to
+override this behavior and control the sidebar on a per-page basis, use the
+`Sphinx html-sidebars configuration value <https://www.sphinx-doc.org/en/master/usage/configuration.html?highlight=html_sidebars#confval-html_sidebars>`_.
