 In this example, when `ntfy subscribe --from-config` is executed:
 
-* Messages to topic `echo-this` will be simply echoed to standard out
-* Messages to topic `get-temp` will publish the CPU core temperature to topic `temp`
-* Messages to topic `alerts` will be displayed as desktop notification using `notify-send`
-* And messages to topic `calc` will open the gnome calculator 😀 (*because, why not*)
+* Messages to `echo-this` simply echos to standard out
+* Messages to `alerts` display as desktop notification for high priority messages using `notify-send`
+* Messages to `calc` open the gnome calculator 😀 (*because, why not*)
+* Messages to `print-temp` execute an inline script and print the CPU temperature
 
 I hope this shows how powerful this command is. Here's a short video that demonstrates the above example:
