 ```console
-k3d image import grafana/tempo:latest --cluster tempo
+k3d image import grafana/tempo:3.0.1 --cluster tempo

 Next either deploy the microservices or the single binary. You can also use tanka [inline environments](https://tanka.dev/inline-environments) to deploy Tempo with either of the two.
