+Inter Variable Font
+===================
+
+This download contains Inter as both variable fonts and static fonts.
+
+Inter is a variable font with these axes:
+  opsz
+  wght
+
+This means all the styles are contained in these files:
+  Inter/Inter-VariableFont_opsz,wght.ttf
+  Inter/Inter-Italic-VariableFont_opsz,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 Inter:
+  Inter/static/Inter_18pt-Thin.ttf

+-----------------------------------------------------------
+
+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

+Noto Sans Symbols Variable Font
+===============================
+
+This download contains Noto Sans Symbols as both a variable font and static fonts.
+
+Noto Sans Symbols is a variable font with this axis:
+  wght
+
+This means all the styles are contained in a single file:
+  Noto_Sans_Symbols/NotoSansSymbols-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 Noto Sans Symbols:
+  Noto_Sans_Symbols/static/NotoSansSymbols-Thin.ttf
+  Noto_Sans_Symbols/static/NotoSansSymbols-ExtraLight.ttf
+  Noto_Sans_Symbols/static/NotoSansSymbols-Light.ttf
+  Noto_Sans_Symbols/static/NotoSansSymbols-Regular.ttf
+  Noto_Sans_Symbols/static/NotoSansSymbols-Medium.ttf
+  Noto_Sans_Symbols/static/NotoSansSymbols-SemiBold.ttf
+  Noto_Sans_Symbols/static/NotoSansSymbols-Bold.ttf
+  Noto_Sans_Symbols/static/NotoSansSymbols-ExtraBold.ttf
+  Noto_Sans_Symbols/static/NotoSansSymbols-Black.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
