+GitHub action for using a matrix strategy to distribute the build for
+`linux/amd64` and `linux/arm64`, and publish to a Docker registry of your choice
+(Docker Hub, ghcr.io or quay.io).
+
+**Inputs**:
+
+- `registry-image` (`string`): Docker image to use as base name for tags.
+- `metadata-tags` (`string`): List of tags as key-value pair attributes.
+  Optional.
+- `registry-address` (`string`): Server address of Docker registry. If not set
+  then will default to Docker registry. Optional.
+- `registry-username` (`string`): Username for authenticating to the Docker
+  registry.
+- `build-context` (`string`): Build's context is the set of files located in the
+  specified PATH or URL. Optional.
+- `build-file` (`string`): Path to the Dockerfile. Optional.
+- `build-provenance` (`boolean`): Generate provenance attestation for the build.
+  Defaults to `false`. Optional.
+- `build-cache-key` (`string`): An explicit key for a cache entry. This will be
+  used in conjunction with the platform set in `build-platforms`, e.g.
+  `coatl-linux-amd64`. Defaults to `coatl`. Optional.
+- `build-digest-key` (`string`): Name of the build digest. This will be used in
+  conjunction with the platform set in `build-platforms`, e.g.
+  `coatl-linux-amd64`. Defaults to `coatl`. Optional.
+
+**Secrets**:
+
+- `registry-password` (`secret`): Password or personal access token for
+  authenticating the Docker registry.
