+# Script to convert coloured images to black and white
+## How to use:
+1. Make the directory structure as shown below:
+<br>.
+<br>├── colour_to_bw.py
+<br>└── image.png
+
+2. Call the function giving two arguments, the path to the original image and the path for your output image
+<br> example :-
+<br>```colour_to_bw("./image.png","./")```
+
+3. The output of the script will be stored as "final_image.png". The directory structure would look similar to this if you execute the code in step 2.
+<br>.
+<br>├── colour_to_bw.py
+<br>├── final_image.png
+<br>└── ptr_mail.apng
