 ## Summary
 
-This tool returns the surface charge for a given structure and list of supplied hkl and offsets.
+This tool returns the total surface charges for a given structure and list of supplied hkl indices and offsets.
 The script provides a GUI that can be used from Mercury or from the command line.
 
-The output is a HTML file with a table for all the all selected surfaces and their associated charge, projected surface areas and normalised surface charge.
+The output is an HTML file with a table for all the selected surfaces and their associated charges, projected surface areas, and normalised surface charges (surface charge per projected area).
 
-Charges are currently calculated using Gasteiger charges. Further development could be made to use user derived charges. Please let me know if that is something you'd like [amoldovan@ccdc.cam.ac.uk](amoldovan@ccdc.cam.ac.uk).
