 # Source Link
 
-Source Link is a language- and source-control agnostic system for providing first-class source debugging experiences for binaries. The goal of the project is to enable anyone building [NuGet libraries to provide source debugging](https://github.com/dotnet/designs/blob/master/accepted/diagnostics/debugging-with-symbols-and-sources.md) for their users with almost no effort. Microsoft libraries, such as .NET Core and Roslyn have enabled Source Link. Source Link is supported by Microsoft.
