 Overview
 ========
 
-This suite of algorithms and software, named xPDFsuite, converts X-ray diffraction (XRD) data into total scattering pair distribution functions by
-numerically transforming XRD data from frequency space into position space. This conversion allows characterization of materials including drugs and
-industrial materials in their amorphous and nanocrystalline and liquid states.
-
-This software implements a number of recent developments in the data analysis and modeling of PDFs derived from X-ray experiments which may be carried out
-at synchrotron or laboratory sources that allow for highly automated and straightforward processing. The software includes a full-featured graphical user
-interface and is designed for the latest generation of studies that involve often many hundreds or thousands of datasets.  The software runs on laptops and
-workstations running windows, mac OSX and linux.
-
+This suite of algorithms and software, named xPDFsuite, is an easy to use graphical user interface (GUI) to a number of Diffpy programs.  
+It provides a raw-data-to-modelled-PDF solution for X-ray PDFs.  It is specially convenient for handling high throughput data with many 
+(hundreds to thousands) of datatsets, such as come from modern synchrotron experiments with 2D detectors. It is equally useful for data 
+from laboratory x-rays.  The software runs on laptops and workstations running windows, mac OSX and linux.
+
+Within the same GUI you can:
+ * visualize the 2D raw data from large numbers of files
+ * integrate 2D data to 1D diffraction patterns
+ * plot and manipulate plots of large numbers of patterns
+ * rapidly and easily process the 1D data to obtain S(Q), F(Q) and G(r) (PDF) functions using the power of the PDFgetX3 engine
+ * use the powerful interactive plotting capabilities to explore these reduced data functions
+ * use built in tools for comparing datasets using Pearson correlations etc.
+ * the widely used PDFgui PDF fitting program is also included in xPDFsuite and is straightforwardly incorporated into your workflow

 Features
 ========
 
-Improving upon an earlier version of the software, xPDFsuite is programmed in Python instead of IDL (Interactive Data Language), making it more portable
-than its predecessor. The software also gives the user robust and reliable total scattering pair distribution functions by specifying a very small number
-of input parameters.
-
-Unlike other programs for obtaining the pair distribution function,
-the software is exceptionally easy to learn and use. This increases
-the range of people who can use it, decreases training costs, and
-speeding up workflow. xPDFsuite also permits users to run multiple
-data sets using the same input file, allowing for batch processing
-in fractions of a second.
