 2. run `npm run dev`
 
+## Webhook Notifications
+
+The application supports webhook notifications for various PI events:
+
+- **Extractor expiry warnings**: Notify when extractors are about to run out (configurable hours before expiry)
+- **Extractor expired**: Notify when extractors have run out
+- **Storage capacity warnings**: Notify when storage is about to be full (configurable percentage)
+- **Storage full**: Notify when storage is at 100% capacity
+- **Launch pad capacity warnings**: Notify when launch pads are about to be full (configurable percentage)
+- **Launch pad full**: Notify when launch pads are at 100% capacity
+
+To enable webhook notifications:
+
+1. Set the `WEBHOOK_URL` environment variable to your Discord webhook URL
+2. Enable webhook notifications in the Settings dialog
+3. Configure warning thresholds for extractors, storage, and launch pads
+
+The webhook URL is kept secure in environment variables and not stored in the browser.
+
 ## Run the container
 
 1. Populate the environment variables in .env file
