Drag fonts to any library to add the fonts to that specific library and to the All Fonts collection.
Drag fonts to any set to add the fonts to that specific set, the set’s parent library, and to the All Fonts collection.
Drag fonts to All Fonts to make the fonts available to other Administrators to add to any library.
You can also click Upload to add fonts to the current library. Connect Fonts will prompt you for the fonts that you want to upload; select the font files and click Open.
