+# Using Multi Config Items
+
+This example uses two different configurations for "using-gogo" and "using-googleapis" through the "scope" field.
+
+It uses the following public libraries:
+* [googleapis](https://github.com/googleapis/googleapis)
+
+The following plug-ins are used:
+* [protoc-gen-go](https://google.golang.org/protobuf/cmd/protoc-gen-go)
+* [protoc-gen-go-grpc](https://google.golang.org/grpc/cmd/protoc-gen-go-grpc)
+* [protoc-gen-grpc-gateway](https://github.com/grpc-ecosystem/grpc-gateway/v2/protoc-gen-grpc-gateway)
+* [protoc-gen-gogo](https://github.com/gogo/protobuf/protoc-gen-gogo)
+
+
+You can compile the proto file in this directory by executing the following command:
+```
+powerproto build -r .
+```
+
+Not surprisingly, you will get the following output:
+```
