 You can start the stack with a full demo dataset:
 
 ```sh
-docker compose \
-  --profile full-demo-dataset \
-  up -d --build
+docker compose --profile full-demo-dataset up -d --build
 ```
 
 You can also add a basic Kubernetes + OCI demo dataset, by running the following command:
 
 ```sh
-docker compose \
-  --profile basic-metadata \
-  --profile k8s-demo-data \
-  up -d --build
+docker compose --profile basic-metadata --profile k8s-demo-data up -d --build
 ```
 
 You will see in a next section how to build this dataset by yourself, in case you want to try with your own Kubernetes cluster.
