-## DESCRIPTION
-
-Mark _image-name_ for deletion.
-The effect of this is registry-specific; many registries don’t support this operation, or don’t allow it in some circumstances / configurations.

-
-**WARNING**: If _image-name_ contains a tag (but not a digest), in the current version of Skopeo this resolves the tag into a digest, and then deletes the manifest by digest, as described above (possibly deleting all tags pointing to that manifest, not just the provided tag). This behavior may change in the future.
