 ## Mono
 
-Mono is a .NET implementation that is mainly used when a small runtime is required. It is the runtime that powered Xamarin applications (now unsupported) on Android, macOS, iOS, tvOS, and watchOS and is focused primarily on a small footprint. Mono also powers games built using the Unity engine.
+The original community and open source .NET. Mono is a cross-platform implementation of .NET Framework. It's the runtime that powered Xamarin applications (now unsupported) on Android, macOS, iOS, tvOS, and watchOS and is focused primarily on a small footprint. Mono also powers games built using the Unity engine.
 
 It supports all of the currently published .NET Standard versions.
 
 Historically, Mono implemented the larger API of .NET Framework and emulated some of the most popular capabilities on Unix. It is sometimes used to run .NET applications that rely on those capabilities on Unix.
 
-Mono is typically used with a just-in-time compiler, but it also features a full static compiler (ahead-of-time compilation) that is used on platforms like iOS.

-## Universal Windows Platform (UWP)
-
-UWP is an implementation of .NET that is used for building modern, touch-enabled Windows applications and software for the Internet of Things (IoT). It's designed to unify the different types of devices that you may want to target, including PCs, tablets, phones, and even the Xbox. UWP provides many services, such as a centralized app store, an execution environment (AppContainer), and a set of Windows APIs to use instead of Win32 (WinRT). Apps can be written in C++, C#, Visual Basic, and JavaScript.
