I was looking for instructions for configuring the QLS URL in qtlicd.ini and found this:
https://doc.qt.io/qtlicenseserver/qls-how-to-install-service.html#configure-the-server-address

It talks about modifying qtlicd.ini in the deploy directory, but that directory is not mentioned anywhere up to that point. How about changing that so it points to the standard per-OS locations where the Qt installer puts it and then mentioning the location for custom builds only afterwards?
