+ * \\brief This is a list of icon codes for the free variant of the
+ * FontAwesome 5.10.1 font.
+ *
+ * \\rst
+ *
+ * This file defines the full listing of
+ * `FontAwesome <https://raw.githubusercontent.com/FortAwesome/Font-Awesome>`_
+ * icons available in NanoGUI.  Please note that if viewing the documentation
+ * on the web, your browser may display the icons differently than what they
+ * look like in NanoGUI.  Run the one of the :ref:`nanogui_example_icons`
+ * executables to see what they all look like in NanoGUI.
+ *
+ * .. tip::
+ *
+ *    In C++, ``#include <nanogui/icons.h>`` to gain access to the ``#define``
+ *    shown in these docs and simply reference the names as listed in the
+ *    documentation.  To use the icons from Python, declare
+ *    ``from nanogui import icons`` and reference the icons as follows:
+ *    ``icons.FA_ASTERISK``.
+ *
+ * The following icons are available:
