 A Python package for the quantitative analysis of the interaction of energetic x-rays with matter.
 This package is named after one of the discoverers of X-rays, `Wilhelm Röntgen <https://en.wikipedia.org/wiki/Wilhelm_Röntgen>`_.
+This is a `SunPy-affiliated package <https://sunpy.org>`_ though it does not depend on the `sunpy package <https://github.com/sunpy/sunpy>`_. We appreciate their support!

+Graphical User Interface
+========================
+This package provides a GUI interface to quickly investigate the absorption and transmission of x-rays through different materials.
+This tool is similar to that provided the `Center for X-ray Optics <https://henke.lbl.gov/optical_constants/>`_.
+To install the dependencies to use the GUI::
 
-::
+    pip install -e .'[gui]'
+
+You can then run it locally with the following command::
 
    bokeh serve --show <roengten_directory>/gui
