 to use an opentelemetry-collector locally.
 
-Another option is to run the local docker compose Jaeger setup in the root of this repo with
-`docker-compose up`. This will bring up a stock Jaeger instance that can accept OTLP connections.
+Another option is to use [`otel-desktop-viewer`](https://github.com/CtrlSpice/otel-desktop-viewer).
