 ## Attestation Limits
 
 ### Subject Limits
 
-No more than 2500 subjects can be attested at the same time. Subjects will be
-processed in batches 50. After the initial group of 50, each subsequent batch
-will incur an exponentially increasing amount of delay (capped at 1 minute of
-delay per batch) to avoid overwhelming the attestation API.
+No more than 1024 subjects can be attested at the same time.

+[jreleaser](https://jreleaser.org/guide/latest/reference/checksum.html) which
+generate a checksums file you can identify the attestation subjects by passing

+artifacts identified in the checksums file will be listed as a subject for the
+attestation.

+line including the hex-encoded digest (either SHA256 or SHA512), a space, a
+single character flag indicating either binary (`*`) or text (` `) input mode,
+and the filename.

+#### Artifact Metadata Storage Records
+
+If the `push-to-registry` option is set to true, the Action will also
+emit an [Artifact Metadata Storage Record](https://docs.github.com/en/rest/orgs/artifact-metadata?apiVersion=2022-11-28#create-artifact-metadata-storage-record).
+Storage records enrich artifact metadata by capturing storage
+related details, such as which registry an image is hosted on
+and whether it's marked as active.
+
+If you do not want to emit a storage record, set `create-storage-record` to `false`.
+
+> **NOTE**: Storage records can only be created for artifacts
+> built from [organization-owned](https://docs.github.com/en/organizations/collaborating-with-groups-in-organizations/about-organizations)
+> repositories.
+
+Artifacts associated with a storage record can be viewed by navigating to
+the `Linked Artifacts` page in your organization:
+`https://github.com/orgs/YOUR_ORG/artifacts`
+(replace `YOUR_ORG` with your organization name).
+
+### Integration with `actions/upload-artifact`
+
+If you'd like to create an attestation for an archive created with the
+[actions/upload-artifact][11] action you can feed the digest of the generated
+artifact directly into the `subject-digest` input of the attestation action.

+```yaml
