+Using the Windows-10 release kit
+================================
+
+You only should need the exe in the release downloads.  That exe is a NSIS installer 
+that will install a folder with the necessary files in a folder you select and a file named
+
+** eiger2cbf.bat **
+
+in C:\Windows and define an environment variable to find the folder you selected.  You 
+should not need to add anything new to your path
+
+Since C:\Windows is in the default path for command windows (cmd), you should be able to 
+run it in any command window.
+
+If you just run
+
+** eiger2cbf.bat **
+
+you should get the help message.
+
+If you have an hdf5 master file, say, c:\myfiles\mydata_master.h5 and want
+the cbfs of frames 37 through 48, then
+
+** eiger2cbf.bat c:\myfiles\mydata_master.h5 37:48 mycbfs_ **
+
+should give you those cbfs.
