 ## Fonts
 
 Font generator generates an extension of `UIFont` and `Font` (or custom classes). It also prints content of `UIAppFonts` from your project `.plist`. If project `.plist` is specified, it will update `UIAppFonts` content of all `.plist`.
 
-iOS required to use the **real name** of the font, this name can be different from its filename. To get the **real name**, it uses `fc-scan`. So, be sure that the `$PATH` contains path of `fc-scan`.
