+
+## Setup Instructions
+### Install python3
+sudo apt-get install python3
+### Install pip (package installer for python)
+sudo apt-get install python3-pip
+### Install OpenCV library with pip
+pip3 install opencv-python
+### Install tkinter library
+sudo apt-get install python3-tk
+
+## Details/Output
+A dialog box appears with three blurring options, average, gaussian and median blurs.
+Selecting any one option prompts user to select an image and applies blur on it.
