+# Notifications Pop Up Plugin – User Guide
+Course: 17-313 Foundations of Software Engineering (Fall 2025)  
+Author: Moza Al Fahad 
+
+---
+
+## 1. Overview
+
+The Notifications Pop Up plugin displays the unread notifications for the user when they first sign in. It gets automatically updated when new notifications arrive. From the pop up which first appears after login, the users have the choice to open the notification or mark all notifications as read. When the user chooses to read the notification, the page redirects them to the notification. 
+
+---
+
+## 2. Features Implemented
+
+- A pop up modal automatically appears when a user logs in and has unread notifications.
+- Uses NodeBB’s built-in WebSockets to update the modal instantly when a new notification arrives.
+- Users can mark individual notifications or mark all as read directly from the pop-up.
+- Simple UI designed to fit within NodeBB’s theme layout for clarity and accessibility.
+- Implemented with a single JS file (unread-pop-lite.js) registered as a NodeBB client script.
+
+---
+
+## 3. How It Works
+
+1. When a user logs in, the plugin checks for any unread notifications.
+2. If unread notifications exist, a pop-up modal is dynamically created and displayed.
+3. Each notification includes a short preview and a link to the related post/topic.
+4. Users can:
+    - Click on a notification to open it, which automatically marks it as read.
+    - Click “Mark All as Read” to clear all unread notifications.
+5. Real-time updates are handled through NodeBB socket events, ensuring new notifications appear immediately without page refreshes.
+6. If no unread notifications exist, the modal does not appear.
+
+---
+
+## 5. Automated Testing & Running Tests
+
+Main test file:
+- Located in test/unread-pop-lite.spec.js
+
+To lint and run tests:
+    npm run lint
+    npm run test:popup
+All tests should pass. 
+
+---
+
+## 6. Front-end Testing
+
+1. Log into NodeBB with a test account.  
+2. Trigger a notification (e.g., mention the test account from another user).  
+3. Verify that:  
+   - On login, a popup appears listing unread notifications.  
+   - Clicking a notification opens the linked post and removes it from the list.  
+   - Clicking “Mark all read” clears the list
