+### Upgrading OpenTelemetry Protos
 
-This project uses a submodule during development, it is not needed if the application is being used as a dependency, so be sure to clone with the option `recurse-submodules`:
+The protos are in a separate repository,
+[opentelemetry-proto](https://github.com/open-telemetry/opentelemetry-proto/),
+and used as a submodule in this repo. To update the Erlang protobuf modules and
+GRPC client first update the submodule and then use the [rebar3 grpcbox
+plugin](https://github.com/tsloughter/grpcbox_plugin/) to generate the client:
 
 ```shell
-$ git clone --recurse-submodules https://github.com/opentelemetry-beam/opentelemetry_exporter
-```
+$ pushd apps/opentelemetry_exporter/opentelemetry-proto
+$ git fetch origin
+$ git checkout <tag>
+$ popd
