 attestations API and associated with the repository from which the workflow was
 initiated.
 
-When an attestation is created, the attestation is stored on the local
-filesystem used by the runner. For each attestation created, the filesystem path
-will be appended to the file `${RUNNER_TEMP}/created_attestation_paths.txt`.
-This can be used to gather all attestations created by all jobs during a the
-workflow.

 Attestations can be verified using the [`attestation` command in the GitHub
 CLI][5].
