= Configuring image streams and image registries
:context: post-install-image-config
toc::[]
You can update the global pull secret for your cluster by either replacing the current pull secret or appending a new pull secret. The procedure is required when users use a separate registry to store images than the registry used during installation. For more information, see xref:../openshift_images/managing_images/using-image-pull-secrets.adoc#using-image-pull-secrets[Using image pull secrets].
For information about images and configuring image streams or image registries, see the following documentation:

* xref:../registry/configuring-registry-operator.adoc#configuring-registry-operator[Image Registry Operator in {product-title}]
