-Push-to-registry is a GitHub Action for pushing an OCI-compatible image to an image registry, such as Dockerhub, Quay.io, or an OpenShift integrated registry.
+Push-to-registry is a GitHub Action for pushing a container image to an image registry, such as Dockerhub, Quay.io, or an OpenShift integrated registry.
 
 This action only runs on Linux, as it uses [podman](https://github.com/containers/Podman) to perform the push. [GitHub's Ubuntu action runners](https://github.com/actions/virtual-environments#available-environments) come with Podman preinstalled. If you are not using those runners, you must first [install Podman](https://podman.io/getting-started/installation).
