+### System Tray (Optional)
+
+If you have waytray installed, I38 provides keyboard-accessible system tray functionality through the StatusNotifierItem (SNI) protocol. This allows you to interact with applications that use the system tray for status indicators or minimize to tray.
+
+**Features:**
+- Access minimized applications (Discord, Slack, Telegram, etc.)
+- View and interact with status indicators (NetworkManager, volume, VPN, etc.)
+- Control background services through their tray context menus
+- Full keyboard navigation without mouse required
+
+**Usage:**
+1. Press `Control` + `Alt` + `Tab` to enter Panel Mode
+2. Press `t` to open the system tray window
+3. Use arrow keys to navigate between tray items
+4. Press `Enter` or `Space` to activate the selected item
+5. Press `Menu` key or `Shift` + `F10` to open context menus
+6. Press `Escape` to close the tray window
+
+**Installation:**
+waytray is an optional dependency. If installed, I38 will automatically configure it to provide only system tray functionality (battery, weather, and system information are disabled to avoid duplication with I38's panel utilities).
+
+*Note:* Without waytray installed, applications that require a system tray to run may not work with I38. However, many applications offer alternative ways to run without a tray.
