+# Go Deduplicator 
+
+Similar to the traditional [fdupes](https://github.com/adrianlopezroche/fdupes)
+command. Though this one is written in go, utilizes sha256, gives you the
+ability to cache the scan and delete the duplicates via a regex.
+
+It's also smart enough not to blow away your files if your regex matches
+all of the files. ( Since the program does not know files you actually
+want to keep )
