 ======
 
-Lots of wonderful text about this being a GUI to do a Fourier transform.
+**ADDIE** stands for **AD**vandced **DI**ffraction **E**nvironment, a data reduction application for total scattering powder diffraction data. 
 
+The name came about from being developed for the Diffraction Group at SNS located at ORNL (and previously known as the Advanced Diffraction Group).

---------
+This "reduction" entails taking raw neutron counts from detectors in the diffraction experiment and turning them into the reciprocal-space structure factor patterns, F(Q) or S(Q), and applying a Fourier Transform to real-space to give the pair distribution fuction, PDF.
+
+ADDIE is a front-end GUI for total scattering that hopes to support multiple diffractometers performing total scattering measurements. The back-end that uses the [Mantid Framework](https://docs.mantidproject.org/nightly/) is the [`mantid-total-scattering`](https://github.com/marshallmcdonnell/mantid_total_scattering) project.

 Before doing the normal `python setup.py ...` things you must convert the
 `designer/*.ui` files to `addie*.py`. This is done with
