 == Uninstalling a Demo
 
-Currently, there is no support for uninstalling a demo again. However, this functionality will come soon.
+To uninstall a demo, you can run the following command, specifying the namespace the demo was installed in.
+
+[source,console]
+----
+$ stackablectl demo uninstall trino-taxi-data -n <NAMESPACE>
+
+----
+
+[NOTE]
+====
+The uninstall command deletes the namespace the demo was installed in. Therefore it is not possible to uninstall demos in the `default` namespace.
+====
+
+[WARNING]
+====
+Currently, some resources deployed by the demo are either still lingering after the deletion process or need to be deleted before running the uninstall command.

+* All demos
+  ** MutatingWebhookConfiguration `restarter-sts-enricher.stackable.tech` is not deleted
+* end-to-end-security, argo-cd-git-ops, hbase-hdfs-load-cycling-data, jupyterhub-pyspark-hdfs-anomaly-detection-taxi-data

+* argo-cd-git-ops
+  ** Delete the ArgoCD Applications `airflow`, `airflow-postgres`, `minio`, and `sealed-secrets`
+  ** Then you can delete the namespaces `stackable-airflow`, `minio`, and `sealed-secrets`
+  ** Delete the ArgoCD ApplicationSet `stackable-operators` and wait for ArgoCD to delete the Applications of that ApplicationSet
+  ** Only after deleting the above, run the `stackablectl demo uninstall` command, otherwise the deletion might get stuck
