+# Blending Images
+This python script will allow us to linear blend two images depending on given alpha - the amount of blending.
+
+## 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 option to enter alpha (the degree of blending, 0 to 1), and select images 1 and 2. Then clicking proceed will display the blended image and stores it in the current folder.
