  Thank you for checking out fontconfig-infinality-ultimate.

  By default, fontconfig will use presets for the free font collection
  from [infinality-bundle-fonts] repository.

  If you are going to use either a custom font collection or core
  Microsoft families, set the appropriate presets using
  fc-presets command.
