 Go users can just `go get` the code directly. For example:

 go get github.com/apache/beam/sdks/v2/go/pkg/beam

 Developers must invoke Go for cross-compilation manually, if desired.
 
 If you make changes to .proto files, you will need to rebuild the generated code.
 Consult `pkg/beam/model/PROTOBUF.md`.
 
 If you make changes to .tmpl files, then add the specialize tool to your path.
 You can install specialize using:
-```

+```bash
 go get github.com/apache/beam/sdks/v2/go/cmd/specialize
 ```

 Add it to your path:
-```
