 This is how you call the same method using `gdbus`:
 
 ``` bash
-gdbus call --system --dest org.freedesktop.UPower --object-path /org/freedesktop/UPower --method org.freedesktop.DBus.Introspectable.Introspect
+gdbus call --system --dest org.freedesktop.UPower --object-path /org/freedesktop/UPower --method org.freedesktop.UPower.EnumerateDevices
 ```
 
 You can also introspect with `gdbus` using a method call instead of the `introspect` command:
 ``` bash
-gdbus call --system --dest 
+gdbus call --system --dest org.freedesktop.UPower --object-path /org/freedesktop/UPower --method org.freedesktop.DBus.Introspectable.Introspect
+```
 
 ## Using Gio
 
+``` python
+from gi.repository import Gio
 
+bus = Gio.bus_get_sync(Gio.BusType.SYSTEM, None)
+proxy = Gio.DBusProxy.new_sync(bus, Gio.DBusProxyFlags.NONE, None, 'org.freedesktop.UPower', '/org/freedesktop/UPower', 'org.freedesktop.DBus.Introspectable', None)
+res = proxy.call_sync('Introspect', None, Gio.DBusCallFlags.NO_AUTO_START, 500, None)
+```
