 This makes WoL very convenient - I can wake the cluster from anywhere in my home, whether I'm on WiFi or ethernet.
 
+## Remote Shutdown via SSH
+
+While Wake-on-LAN handles powering on the machines remotely, I also added a shutdown function to the script for convenience. The `wol-f3s shutdown` command uses SSH to connect to each machine and execute `doas poweroff`, gracefully shutting them all down.
+
+This is particularly useful for power saving - when I'm done working with the cluster for the day, I can simply run:
+
+```sh
+[paul@earth]~% wol-f3s shutdown
+```
+
+And all three machines will shut down cleanly. The next time I need them, a simple `wol-f3s` command wakes them all back up. This combination makes the cluster very energy-efficient while maintaining quick access when needed.
+
 ## BIOS Configuration
 
 For WoL to work reliably, make sure to check the BIOS settings on each Beelink:
