+# Plagiarism Detector
+This script helps to detect the amount (percentage) of similarity between 2 files .
+
+## Input
+It takes paths of 2 files you want to compare as input
+
+## Output
+It returns the percentage of similarity between the 2 files

+## Python script to watermark your images
+
+in the `main.py` file edit the following items:
+
+```bash
+        "<input folder>",
+        "<output folder>",
+        "<watermark image>"
+```
+
+using the input folder path to loop over all images and output them to outputfolder.
+
+Best practise is to use a image with transparent background.
