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