+# Directory description
+
+This directory contains scripts to test the output of your current version of WCSim with the version on GitHub. 
+The purpose of these scripts is to ensure that the changes being committed will not accidentally change the output of the WCSim code. 
+
+# Description of scripts in this directory
+
+## verification_HitsChargeTime.C: 
+
+This script will test a .root output file from your version of WCSim against the committed version of the code. 
+This test plots the number of digitized hits, the average charge, and the average time. 
+A ks test is printed to the screen. This test also prints to the screen a comparison of the first event in the files to see if the number of hit tubes, number of digitized tubes, and number of pe hit times match. 
+
+### Usage
+To use the verification_HitsChargeTime test in the default method, do the following steps:
+* clone a copy of the current code from GitHub into a directory called WCSim_clean. Compile the code. 
+* Go to WCSim_clean/verification-test-scripts and run electrontest.mac by typing: ../bin/Linux-g++/WCSim electrontest.mac . This should produce an output file called wcsimtest.root in the verification-test-scripts directory of WCSim_clean. 
+* Go to the verification-test-scripts directory of your local WCSim (with your changes you wish to commit) and run the macro electrontest.mac in WCSim by typing ../bin/Linux-g++/WCSim electrontest.mac. This should produce a file called wcsimtest.root in your verification-test-scripts directory. 
+* Still in the verification-test-scripts of your local WCSim directory, type: root verification_HitsChargeTime.C
+
+You can also use this test to compare any two files from any two directories. To use the script this way type:
+* root 
+* .x verification_HitsChargeTime.C("/path/to/first_file", "/path/to/second_file")
