It’s easy to set up, but take care not to add too many fonts at once or you might slow GIMP’s load time. If you’ve already got a folder full of fonts and you don’t want to move them around, you can tell GIMP where to find them and it will scan and load them in their current location.

On the left pane, scroll down to find the Folders section and expand it by clicking the small + icon beside it, then select Fonts. Open GIMP, and open the Preferences dialog.
