+-----------------------------------------------------------
+
+PREAMBLE
+The goals of the Open Font License (OFL) are to stimulate worldwide
+development of collaborative font projects, to support the font creation
+efforts of academic and linguistic communities, and to provide a free and
+open framework in which fonts may be shared and improved in partnership
+with others.
+
+The OFL allows the licensed fonts to be used, studied, modified and
+redistributed freely as long as they are not sold by themselves. The
+fonts, including any derivative works, can be bundled, embedded, 
+redistributed and/or sold with any software provided that any reserved
+names are not used by derivative works. The fonts and derivatives,
+however, cannot be released under any other type of license. The
+requirement for fonts to remain under this license does not apply
+to any document created using the fonts or their derivatives.
+
+DEFINITIONS
+"Font Software" refers to the set of files released by the Copyright

+binary files as long as those fields can be easily viewed by the user.
+
+3) No Modified Version of the Font Software may use the Reserved Font
+Name(s) unless explicit written permission is granted by the corresponding

+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
+  static/OpenSans_SemiCondensed-ExtraBold.ttf
+  static/OpenSans-Light.ttf
+  static/OpenSans-Regular.ttf
+  static/OpenSans-Medium.ttf
+  static/OpenSans-SemiBold.ttf
+  static/OpenSans-Bold.ttf
+  static/OpenSans-ExtraBold.ttf
+  static/OpenSans_Condensed-LightItalic.ttf
+  static/OpenSans_Condensed-Italic.ttf
+  static/OpenSans_Condensed-MediumItalic.ttf
+  static/OpenSans_Condensed-SemiBoldItalic.ttf
+  static/OpenSans_Condensed-BoldItalic.ttf
+  static/OpenSans_Condensed-ExtraBoldItalic.ttf
+  static/OpenSans_SemiCondensed-LightItalic.ttf
+  static/OpenSans_SemiCondensed-Italic.ttf
+  static/OpenSans_SemiCondensed-MediumItalic.ttf
+  static/OpenSans_SemiCondensed-SemiBoldItalic.ttf
+  static/OpenSans_SemiCondensed-BoldItalic.ttf
+  static/OpenSans_SemiCondensed-ExtraBoldItalic.ttf
+  static/OpenSans-LightItalic.ttf
+  static/OpenSans-Italic.ttf
+  static/OpenSans-MediumItalic.ttf
+  static/OpenSans-SemiBoldItalic.ttf
+  static/OpenSans-BoldItalic.ttf
+  static/OpenSans-ExtraBoldItalic.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
+available styles
