+How to Update EPPlus
+====================
+
+We use the EPPlus library to read MS Office Open XML (OOXML) files. 
+This includes both MS Excel files and Google Sheets exported in MS Office Open XML format.
+We do this both when the user "adds" a new Excel or Google worksheet through the Editor, and when the user "regenerates" a table in the Editor.
+Using EPPlus allows us to use the same complex "type inference" code for both Excel and Google Sheets.
+When a Google Sheet is being used, we ask Google Sheets to export the workbook and all of its worksheets as an Excel document.
+
+We obtained the EPPlus library from http://epplus.codeplex.com/ .
+
+The source code for EPPlus is checked in to Git. 
+It is located in folder GitHub\EPPlus.
+ 
+The branches are described here https://github.com/afader/EPPlus

+The following branches are present:
+1.	Official – The EPPlus source code we are currently using as the base source code.
+2.	AppSheet – The Official version with our changes applied.
