params definition is not clear

Hi,
I read the document: https://github.com/concourse/oci-build-task#params, the description is not clear:

$REGISTRY_MIRRORS (default empty): registry mirrors to use for docker.io.

If I set like this, does that means it will pull image 'node:12' from xxx.test.com instead of docker.io:
[taks configuration]

params:
  REGISTRY_MIRRORS: xxx.test.com

[Dockerfile]
FROM node:12

Any have any idea how to configure the REGISTRY_MIRRORS

I am using this and it is not working

            CONTEXT: source-code/
            BUILD_ARG_BUILD_PROFILE: test
            REGISTRY_MIRRORS:
              - host: ((sfDockerMirror.host))
              - username: ((sfDockerMirror.username))
              - password: ((sfDockerMirror.password))

not working

the task still trying to fetch images from docker.io
