By default, your library shows a short message when there is nothing to display. You can replace this with your own wording, which is helpful for guiding visitors or matching your tone of voice.
Where to find it
Open Settings and go to the Advanced tab. You will find fields for the empty-library messages there.
The two messages
There are two separate messages you can set. One appears when the library contains no documents at all. The other appears when a visitor’s search or filter returns no matching documents, so you can word each for its situation, for example inviting visitors to clear their filters and try again.
