+- The python script helps users to know if their passwords were ever part of a data breach, and thus helping them stay aware and change their passwords accordingly
+- The script uses haveibeenpwned.com API to obtain relevant data regarding your passwords and how many times it has occured in the dataset, indicating breaches.
+
+## Intalling requirements:
+
+```sh
+    $ pip install -r requirements.txt
+```
+
+## Running the script:
+
+```sh
+    $ python pwned_passwords_GUI.py
+```
