## OpenTelemetry

If your project uses [OpenTelemetry](https://opentelemetry.io/) and you would like spans to propagate through the gateway, you can refer to the [OpenTelemetry gRPC-Gateway Boilerplate](https://github.com/iamrajiv/opentelemetry-grpc-gateway-boilerplate) project. This repository provides a sample project that showcases the integration of OpenTelemetry with gRPC-Gateway to set up an OpenTelemetry-enabled gRPC-Gateway REST server. The project includes a simple `SayHello` method implemented on the gRPC server that returns a greeting message to the client.
