+Open Sans Variable Font
+=======================
+
+This download contains Open Sans as both variable fonts and static fonts.
+
+Open Sans is a variable font with these axes:
+  wdth
+  wght
+
+This means all the styles are contained in these files:
+  OpenSans-VariableFont_wdth,wght.ttf
+  OpenSans-Italic-VariableFont_wdth,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 Open Sans:
+  static/OpenSans_Condensed-Light.ttf
+  static/OpenSans_Condensed-Regular.ttf
+  static/OpenSans_Condensed-Medium.ttf
+  static/OpenSans_Condensed-SemiBold.ttf
+  static/OpenSans_Condensed-Bold.ttf
+  static/OpenSans_Condensed-ExtraBold.ttf
+  static/OpenSans_SemiCondensed-Light.ttf
+  static/OpenSans_SemiCondensed-Regular.ttf
+  static/OpenSans_SemiCondensed-Medium.ttf
+  static/OpenSans_SemiCondensed-SemiBold.ttf
+  static/OpenSans_SemiCondensed-Bold.ttf
