+
+This Codespace can help you debug the source build of .NET. In case you have run this from a
+`dotnet/installer` PR branch, it will contain the VMR (`dotnet/dotnet`) checked out into
+`/workspaces/dotnet` with the PR changes pulled into it. You can then attempt to source-build
+the VMR which is what the VMR leg in the installer PR build doing. This build takes about 45
+minutes and, after completion, produces an archived .NET SDK in `/workspaces/artifacts/x64/Release`.
+
+To build the VMR, run following:
+```bash
+cd /workspaces/dotnet
+unset RepositoryName
+./build.sh --online
+```
+
+> Please note that, at this time, the build modifies some of the checked-in sources so it might
+be preferential to rebuild the Codespace between attempts.
+
+For more details, see the instructions at https://github.com/dotnet/dotnet.
