 ## Generating code
 
-This repository does not publish the generated code, but it does run Thrift and `protoc` generators as part of the CI to verify all IDL files. See the [Makefile](./Makefile) for example. In particular, the classes for different languages can be compiled using the `jaegertracing/protobuf` Docker image (see [README](https://github.com/jaegertracing/docker-protobuf/blob/master/README.md)).
+This repository only include Go code for some of the Thrift and Protobuf modules. It also runs Thrift and `protoc` generators as part of the CI to verify all IDL files. See the [Makefile](./Makefile) for example. In particular, the classes for different languages can be compiled using the `jaegertracing/protobuf` Docker image (see [README](https://github.com/jaegertracing/docker-protobuf/blob/master/README.md)).
 
 To generate the stubs for your own purposes:
   * clone the repository
   * run `make proto-all` or `make thrift-all`
-  * the stubs will be generated under `gen-{lang}` for Thrift and `proto-gen-{lang}` for Protobuf
+  * the stubs will be generated under `.thrift-gen-polyglot/gen-{lang}` for Thrift and `.proto-gen-polyglot/{lang}` for Protobuf
