-## Code Overview
+## Code overview
 
-### Backend (`backend.py`)
+### Backend (`app.py`)
 
 - Uses Flask to handle HTTP requests.
 - Uses IMAP to connect to the email server and fetch emails.
-- Uses scikit-learn to classify emails as phishing or not based on the subject and sender.
+- Uses scikit-learn to classify emails as suspicious or not based on the content.
-- Provides endpoints for login, checking mail, marking emails as safe, and moving emails to trash.
+- Provides endpoints for fetching emails, classifying emails, marking emails as safe, and deleting emails.
 
 ### Frontend
 
 - `popup.html`: The main interface of the extension.
-- `popup.js`: Handles interactions in the popup, such as login, checking mail, and handling responses.
+- `popup.js`: Handles interactions in the popup, such as login, fetching emails, and handling responses.
-- `background.js`: Listens for messages from the popup and handles notifications.
+- `background.js`: Manages the background tasks of the extension, such as opening the popup.
-- `notification.html` & `notification.js`: The interface and logic for the notification popup.
+- `styles.css`: Contains the styles for the extension's UI.
+- `manifest.json`: Configuration file for the Chrome extension.
+- `images/icon16.png`, `images/icon48.png`, `images/icon128.png`: Icons used for the extension.
 
-## API Endpoints
+## API endpoints
 
-- `POST /login`: Login with email credentials.
+- `POST /fetch-emails`: Fetch emails from the email server.
-- `GET /check_mail`: Check for new emails and classify them.
+- `POST /classify-email`: Classify an email as phishing or not.
-- `POST /logout`: Logout from the email account.
+- `POST /mark-safe`: Mark an email as safe.
-- `POST /mark_safe/<email_id>`: Mark an email as safe.
+- `POST /delete-email`: Delete an email from the email server.
-- `POST /move_trash/<email_id>`: Move an email to the trash.
 
+## Files and directories
 
+### Backend directory
+
+- `app.py`: Main Flask application file.
+- `spam_classifier_model.pkl`: Pre-trained machine learning model for classifying emails.
+- `vectorizer.pkl`: Pre-trained vectorizer for transforming email content into a format suitable for the classifier.
+- `source.txt`: Contains a link from which the datasets were downloaded.
+- `lingSpam.csv`, `enronSpamSubset.csv`, `completeSpamAssasin.csv`: These are the datasets used to train the model (Random Forest is the chosen model).
+- `data_join.py`: Script which merges the three datasets into one CSV file called `joined_data.csv`.
+- `joined_data.csv`: The combined dataset resulting from `data_join.py`.
+- `ML.ipynb`: Jupyter notebook containing all the machine learning and vectorizer information.
+- `requirements.txt`: File containing the list of required Python packages.
+
+### Extension directory
+
+- `popup.html`: The main HTML file for the extension's UI.
+- `popup.js`: JavaScript for handling UI interactions and communicating with the backend.
+- `background.js`: JavaScript for background tasks and managing the extension's lifecycle.

+
+## How it works
+
+1. **Login**: Users log in with their email credentials using the extension.
+2. **Fetch emails**: The extension fetches emails from the server and displays them in the popup.
+3. **Classify emails**: Emails are classified as suspicious or not. The classification results are stored and associated with each email.
+4. **Mark as safe/Delete**: Users can mark suspicious emails as safe or delete them. The actions are reflected in the backend and the UI is updated accordingly.
