+# Image-Inverter
+
+## Describtion
+This project is an implementaion of a CLI program that inverts image/set of images.
+
+## Requirements
+First, you need to install `pillow` module. You can check the official instructions [here](https://pillow.readthedocs.io/en/stable/installation.html) and follow the instructions according to the OS you are running.
+
+## Examples
+### Command
+`./inverter.py /your/path/to/image.jpg /another/img.png`
+
+OR: you can use `-v` or `--verbose`:
+`./inverter,py -v /your/image.webp`
+
+NOTE: **output** images will be generated in the **current working directory**
