-Although we are using the dev-cluster here again, this is different from

-previously](../dev-cluster/2-run-dev-cluster-locally.md). In this instance, we

-block explorer, and faucet will run (like before), but we will not be running

+Kubernetes (k8s) cluster where we will deploy our local rollup.

 Make sure that Docker is running before deploying with `just`.

-full dev-cluster is run locally, the sequencer and DA are not spun up. The
-dev-net is already running remotely.
+This gives us a local environment compatible with our helm charts.
