 This repo contains the code to build the .NET Core runtime, libraries and shared host (`dotnet`) installers for
 all supported platforms. It **does not** contain the actual sources to .NET Core runtime; this source is split across
 the dotnet/coreclr repo (runtime) and dotnet/corefx repo (libraries).
