   If you want to use the [k6 Docker image](https://hub.docker.com/r/grafana/k6) to run k6, you need to run the Quickpizza and k6 containers within the same network.
 
   First, create a Docker network. Then, run Quickpizza, assigning a hostname and connecting to the created network.
 
   ```bash
-    docker network create quickpizza_network
-    docker run --network=quickpizza_network --hostname=quickpizza --rm -it -p 3333:3333  ghcr.io/grafana/quickpizza-local:latest
+  docker network create quickpizza_network
+  docker run --network=quickpizza_network --hostname=quickpizza --rm -it -p 3333:3333  ghcr.io/grafana/quickpizza-local:latest
   ```
 
   Next, you can use the k6 Docker image to execute the k6 test. Run the k6 Docker container within the same network (`quickpizza_network`) and pass the `BASE_URL` environment variable with the value of the Quickpizza container's hostname as follows:
