+# phodupe
+
+## What is it
+
+A simple little python script that finds duplicate file names (without the extension) across two directories and gives the user the option to delete them.
+
+## Why
+
+I used this as an opportunity to begin learning python. It was created for a very very specific scenario and might not be too useful to anyone else.
+
+## How do to install / run
+
+(There are probobly better ways to run this, but i'm a python noob)
+
+- Navigate to the folder you downloaded the git project to
+  - cd \development\git\Phodupe\
+- Install the python script
+  - python .\setup.py install
+- Run the script by passing two directories
+  - python phodupe "C:\Users\NYPD\Desktop\OG Phone Walls" "C:\Users\NYPD\Desktop\2Delete"
