Making self-published Device handler available in all my locations



I have written my first own device handler. It is available - as well as a device create on the basis of this device type - in my location “myLab”. But “myLab” has no real hub available. My real hub is in the location “home”.
Even after “publishing” the device handler, it is not available in the “home” location to create devices based on that device type.
How can I get it there?

If you answer with a link, I will be happy, too. I know that this is a very basic question.
