 > [!NOTE]
 > Why Rocky instead of RHEL's "ubi" container images? According to [Types of container images](https://docs.redhat.com/en/documentation/red_hat_enterprise_linux/9/html/building_running_and_managing_containers/assembly_types-of-container-images_building-running-and-managing-containers#assembly_types-of-container-images_building-running-and-managing-containers), Red Hat Universal Base images ("ubi") are built from a subset of the normal Red Hat Enterprise Linux content, so you have access to free dnf repositories for adding and updating software. A subset of the CRB repo is also available, and that's why EPEL is installable. If you need more packages, you will need to purchase a (developer) subscription or run the container on a subscribed host.
 
+> [!NOTE]
+> Why `docker.io/rockylinux/rockylinux` instead of `docker.io/library/rockylinux`?  
+> `docker.io/library/rockylinux` is currently not updated: "The Docker team curates the Official Images program, and there are currently some technical constraints preventing Rocky Linux from publishing updates here. For the most up-to-date container images, please refer to [the Rocky Linux Docker Hub repository](https://hub.docker.com/r/rockylinux/rockylinux) for now."
