+| Path | Description |
+|------|-------------|
+| `/opt/nupst/` | Main installation directory containing the NUPST files |
+| `/etc/nupst/config.json` | Configuration file |
+| `/usr/local/bin/nupst` | Symlink to the NUPST executable |
+| `/etc/systemd/system/nupst.service` | Systemd service file (when enabled) |
+
+### Service Changes
+
+- Creates and enables a systemd service called `nupst.service` (when enabled with `nupst enable`)
+- The service runs with root permissions to allow system shutdown capabilities
+
+### Network Access
+
+- NUPST only communicates with your UPS device via SNMP (default port 161)
+- Brief connections to npmjs.org to check for updates
+
 ## Uninstallation
 
 ```bash
+# Using the CLI tool:
+sudo nupst uninstall
+
 # If installed from git repository:
 cd /path/to/nupst
 sudo ./uninstall.sh
