+# Image Circulator
+Tiny Python3 script to make your images circular.
+
+## Dependencies
+ It requires `python3` and `pillow`.
+ To install `pillow`, you need `pip3` or python3.
+
+## Usage
+To run, from the command line type:
+
+`python3 image_circulator.py -i INPUT_FILE_PATH -o OUTPUT_FILE_PATH -d DIAMETER_IN_PIXELS`
+
+Or make the script executable.
