 Removing a library from the shared framework is a breaking change and should be avoided.
 
+### References to libraries in the shared framework that produce packages
+
+It's beneficial to avoid project references to libraries that are in the shared framework because it makes the package graph smaller which reduces the number of packages that require servicing and the number of libraries that end up being copied into the application directory.
+
+If a dependency is part of the shared framework a project/package reference is never required on the latest version (`NetCoreAppCurrent`).  A reference is required for previous .NET versions even if the dependency is part of the shared framework if the project you are building targets .NETStandard and references the project there.  You may completely avoid a package dependency on .NETStandard and .NET if it's not needed for .NETStandard (for example - if it is an implementation only dependency and you're building a PNSE assembly for .NETStandard).
+
+Warning NETPKG0001 is emitted when you have an unnecessary reference to a library that is part of the shared framework.  To avoid this warning, make sure your ProjectReference is conditioned so that it doesn't apply on `NetCoreAppCurrent`.
+
 ## Transport package
 
 Transport packages are non-shipping packages that dotnet/runtime produces in order to share binaries with other repositories.

@@ -16,6 +16,10 @@ If a library is packable (check for the `<IsPackable>true</IsPackable>` property
 
 When you make a change to a library & ship it during the servicing release, the `ServicingVersion` must be bumped. This property is found in the library's source project. It's also possible that the property is not in that file, in which case you'll need to add it to the library's source project and set it to 1. If the property is already present in your library's source project, just increment the servicing version by 1.
 
+## Optionally ensure all up-stack packages are also produced
+
+If you wish to ensure that every package that references a serviced package is also serviced itself, you can enable validation by setting `ServiceTransitiveDependencies` to true.  This can be done in an individual project, or globally.  When doing this then building the repo, eg: `build libs -allConfigurations` you'll see errors from any project that didn't enable servicing.  Reasons for forcing packages which depend on your package to service are security servicing or removing dependencies.
