+Source Code Pro Variable Font
+=============================
+
+This download contains Source Code Pro as both variable fonts and static fonts.
+
+Source Code Pro is a variable font with this axis:
+  wght
+
+This means all the styles are contained in these files:
+  Source_Code_Pro/SourceCodePro-VariableFont_wght.ttf
+  Source_Code_Pro/SourceCodePro-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 Source Code Pro:
+  Source_Code_Pro/static/SourceCodePro-ExtraLight.ttf
+  Source_Code_Pro/static/SourceCodePro-Light.ttf
+  Source_Code_Pro/static/SourceCodePro-Regular.ttf
+  Source_Code_Pro/static/SourceCodePro-Medium.ttf
+  Source_Code_Pro/static/SourceCodePro-SemiBold.ttf
+  Source_Code_Pro/static/SourceCodePro-Bold.ttf
+  Source_Code_Pro/static/SourceCodePro-ExtraBold.ttf
+  Source_Code_Pro/static/SourceCodePro-Black.ttf
+  Source_Code_Pro/static/SourceCodePro-ExtraLightItalic.ttf
+  Source_Code_Pro/static/SourceCodePro-LightItalic.ttf
+  Source_Code_Pro/static/SourceCodePro-Italic.ttf
+  Source_Code_Pro/static/SourceCodePro-MediumItalic.ttf
+  Source_Code_Pro/static/SourceCodePro-SemiBoldItalic.ttf
+  Source_Code_Pro/static/SourceCodePro-BoldItalic.ttf
+  Source_Code_Pro/static/SourceCodePro-ExtraBoldItalic.ttf
+  Source_Code_Pro/static/SourceCodePro-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
+available styles
