+:description: Overview of Stackable's artifact registries where container images and Helm Charts are published to.
+
+Currently, the SDP operator and product container images, as well as the Helm Charts are published on two registries: `oci.stackable.tech` and `quay.io`.
+This page details in which structure these artifacts are stored and can be retrieved.
