@sudo-bmitch, can you help us understand the ordering of the displayed list?
If you alpha sort the displayed values, wouldn't it be:

CNCF distribution
CNCF ORAS Artifacts Spec
Docker buildkit
Google go-containerregistry/crane
OpenSSF sigstore/cosign
regclient
zot

It's sorted by the link.

True, but it feels weird to change the order when something gets donated, like Docker Distribution to CNCF Distribution. Do we need to strip off the parent orgs to reduce confusion? I usually just call it Kubernetes and not CNCF Kubernetes.

Can you also help understand why this list is added to the readme.md as opposed to implementations

was why I was asking for a description regarding reason for link here.. a brief comment relating what each project may be doing, normally from the project owners if they would comment and/or approve the mention

i'm fine either way, starting here and updating in a follow up or add just enough explanation here.. to make alpha order obvious I guess just show the string being used..

While we're adding things, might as well also add ko since it attaches SBOMs to images by default, using the same mechanism as cosign.

As a contributor to cosign, and maintainer of crane and ko, if we think we need a little text blurb, I can propose:

- [cosign][cosign] supports attaching signatures, SBOMs and attestations to images in a manner supported by [many registry implementations](https://github.com/sigstore/cosign#registry-support)
- [crane][crane] supports modifying and moving artifacts between supported registry implementations
- [ko][ko] supports building images for Go applications, including attaching SBOMs using cosign's implementation

If we don't have a statement from the project owner, should we remove them from the above list? My goal was to be inclusive without triggering a debate over wording of a description that would delay this getting merged.

What specific changes are being requested that would result in the project maintainers approving and merging this?

- [Google go-containerregistry/crane][crane]
