-Rokkitt Variable Font
-=====================
-
-This download contains Rokkitt as both variable fonts and static fonts.
-
-Rokkitt is a variable font with this axis:
-  wght
-
-This means all the styles are contained in these files:
-  Rokkitt-VariableFont_wght.ttf
-  Rokkitt-Italic-VariableFont_wght.ttf
-
-If your app fully supports variable fonts, you can now pick intermediate styles
-that aren’t available as static fonts. Not all apps support variable fonts, and
-in those cases you can use the static font files for Rokkitt:
-  static/Rokkitt-Thin.ttf
-  static/Rokkitt-ExtraLight.ttf
-  static/Rokkitt-Light.ttf
-  static/Rokkitt-Regular.ttf
-  static/Rokkitt-Medium.ttf
-  static/Rokkitt-SemiBold.ttf
-  static/Rokkitt-Bold.ttf
-  static/Rokkitt-ExtraBold.ttf
-  static/Rokkitt-Black.ttf
-  static/Rokkitt-ThinItalic.ttf
-  static/Rokkitt-ExtraLightItalic.ttf
-  static/Rokkitt-LightItalic.ttf
-  static/Rokkitt-Italic.ttf
-  static/Rokkitt-MediumItalic.ttf
-  static/Rokkitt-SemiBoldItalic.ttf
-  static/Rokkitt-BoldItalic.ttf
-  static/Rokkitt-ExtraBoldItalic.ttf
-  static/Rokkitt-BlackItalic.ttf
-
-Get started
------------
-
-1. Install the font files you want to use
-
-2. Use your app's font picker to view the font family and all the
