 The `-d` debug flag can be useful for testing rules without executing the commands. It can be tricky finding a single event (and, usually, you want the *last* event) in the series of events udev will report for a given device; generally, you want to try to find a rule that will execute exactly once per plug event.  For example, when I connect that Goldtouch keyboard above, udev spews out a dozen `add` events that seem to correspond with each function the keyboard supports, so it took a bit to find a rule that triggered only once.
 
+Put the rules file in `$XDG_CONFIG_HOME/kbplug/rules.json` or specify the file path on the command line, like this:

+```
+kbplug myrules.json
