 ## Cutting a new release
 
-Use [goreleaser](https://goreleaser.com/):
-
 Example of releasing `v0.1.0`:
 ```
 git tag -a v0.1.0 -m "Release v0.1.0"
 git push origin v0.1.0
-goreleaser
 ```
 
+A Codefresh pipeline will pick up the GitHub tag event
+and run [.codefresh/release.yml](.codefresh/release.yml).
+
+This will result in running [goreleaser](https://goreleaser.com/)
+to upload release artiacts, as well as push a tag to Docker Hub for
+the image `ocistorage/oras`.
