 ## Usage
 
+### `docker-compose`
+
+By default runs against the `otel/opentelemetry-collector-dev:latest` image, and uses the `tonic`'s
+`grpc` example as the transport.
+
+```shell
+docker-compose up
+or
+docker-compose up -d
+```
+
+In another terminal run the application `cargo run`
+
+Use the browser to see the trace:
+- Jaeger at http://0.0.0.0:16686
+
+Tear it down:
+
+```shell
+docker-compose down
+```
+
+### Manual
+
+If you don't want to use `docker-compose`, you can manually run the `otel/opentelemetry-collector` container
+and inspect the logs to see traces being transferred.
+
 ```shell
 # Run `opentelemetry-collector`
 $ docker run  -p4317:4317 otel/opentelemetry-collector:latest
