+## OpenSans Font
+
+[OpenSans](https://fonts.google.com/specimen/Open+Sans) is an open source humanist sans serif typeface designed by Steve Matteson. It's intended to be a replacement for Segoe UI for Uno applications, as Segoe UI isn't available on some platforms. In Uno 5.3, we introduce the ability to change the default font to OpenSans which is served through [Uno.Fonts.OpenSans NuGet package](https://www.nuget.org/packages/Uno.Fonts.OpenSans). For more information, see [Fonts documentation](https://aka.platform.uno/feature-opensans).
