@krol3 @evalsocket I think we're missing one step to actually send an event to the bot whenever a new release is performed. See for example https://github.com/ahmetb/kubectl-tree/blob/master/.github/workflows/release.yml#L23

The workflow syntax for Github actions works in .github, I didn't notice :( . I updated the PR

[danielpacak]

I pushed one more commit to make the krew manifest template as close to the existing one as possible https://github.com/kubernetes-sigs/krew-index/blob/master/plugins/starboard.yaml

Otherwise it would not get merged automatically.
