 # Requirements
 
-## Windows
-
-In order to build OmniSharp, the [.NET 4.7.2 targeting pack](https://dotnet.microsoft.com/download/dotnet-framework/thank-you/net472-developer-pack-offline-installer) must be installed if it isn't already.
-
-## macOS
-
-**Mono 6.6.0** or greater is required. You can install this using the latest [.pkg](http://www.mono-project.com/download/#download-mac) or install it view [Homebrew](https://brew.sh/):
-
-```
-brew update
-brew install mono
-brew install homebrew/cask/mono-mdk
-```
-
 ## Linux
 
 Because OmniSharp uses the .NET Core SDK as part of the build, not all Linux distros are supported. A good rule of thumb is to check the list [here](https://docs.microsoft.com/dotnet/core/install/dependencies?pivots=os-linux) to see if your particular distro is supported.
 
-**Mono 6.6.0** or greater is required. Each distro or derivative has its own set of instructions for installing Mono which you can find [here](http://www.mono-project.com/download/#download-lin). Be sure to install `msbuild` as well, which may be a separate package.
