 This library can be used to verify these attestations using Rego policy.
 Policy can be used to check whether an attestation is correctly signed, and that the contents of the attestation are correct.
 
-Our overall goal with this project is adoption of the ideas into other open-source projects, rather than to create another standalone tool.
-It would be a great outcome if this library was no longer needed because the functionality was built into other tools.

+`platforms` in the second rule above is optional and can be used to restrict the platforms for which the policy
+ is evaluated. If the `platforms` field is not present, the policy will be applied to all platforms.
+ It's important to note that the `platforms` field is a filter, and is applied before the `pattern`
+ field is processed, so both `platforms` and `pattern` need to match in order for the policy to be selected
+ (or the rewrite to be processed if present).
 
 As before, any repository in the `docker.io/library` namespace will be evaluated against the policy in `doi/policy.rego`.
 The second rule will rewrite any repository in the `public.ecr.aws/docker/library` namespace to `docker.io/library`.
