+You can checkout that package if you want to edit it, and change the npm dependency to the directory you've cloned it
+to e.g. `"arctis-usb-finder": "file:../arctis-usb-finder"`. If you make a change, as it's written in TypeScript you must
+build it first and restart this application to refresh the code.
