service by terminating the expansion service process.
+#### 13.2.3. Using cross-language transforms in a Go pipeline
+
+If a Go-specific wrapper for a cross-language is available, use that;
otherwise, you have to use the
+lower-level
[CrossLanguage](https://pkg.go.dev/github.com/apache/beam/sdks/go/pkg/beam#CrossLanguage)
+function to access the transform.

+**Expansion Services**
+
+The Go SDK does not yet support automatically starting an expansion service.
In order to use
+cross-language transforms, you must manually start any necessary expansion
services on your local
+machine and ensure they are accessible to your code during pipeline
construction; see more at
Review comment:
We should also add something analogous to the following in Python
section.
"Make sure the transform you're trying to use is available and can be used
by the expansion service. For Java, make sure the builder and registrar for the
transform are available in the classpath of the expansion service."
