+# Dedup
+A command line tool to identify and optionally remove duplicate files
+
+The software is provided as is. Use at your own risk.
+
+Usage: Dedup <folder> <options>
+
+This program will find duplicate files within a folder
+
+Options:
+
+-D - delete duplicates, keeping the file with the oldest creation date
+
+-S - show each duplicate
+
+The idea for this tool came to me because I was copying pictures from my iphone to my computer, then later on copying them again as I took
+more and more pictures. After a while I realized I was getting a whole bunch of duplicate pictures on my computer. After a while it became
+unfeasible to manually find and delete duplicate pictures so I created this tool to automate the process.
+
+It can be used for any file types, I just happen to use it for pictures. It doesn't use the file name to determine if a file is a copy,
+it goes by file contents.
