+# Application Opener
+## Overview:
+
+This script checks through a directory to see if there are any duplicates.
+
+## Why would you find that useful?
+
+It's useful so you don't need to open and close every file to see if you have any unnecessary files.
+
+
+## How would you setup your own startup script?
+
+1. As long as it is executable it should work (a quick "chmod +x" should do the trick)
+2. The full path of the directory you're checking is an input, so keep that copied (everything else will be prompted to you)
+
