+# Simple XOR Image encryptor
+
+## Features
+
+0. encrypt and decrypt image with xor bitwise operation
+1. 2 modes of operation, enc and dec
+
+## Usage
+
+You can run it by typing
+
+```
+python script.py
+```
+
+After that, you can enter path to your image you want to encrypt/decrypt, and then select mode of operation.
