 Installation:
   - Rename 'fonts.json.txt' to 'fonts.json', move into your /config folder and overwrite - unless you have previously made changes to the file, in which case you will need to modify it manually to save your changes. Make sure 'fonts.json' no longer remains in the graphical overmap mod folder.
