Documentation for Multiple satellite services no longer works

FYI, the documentation for setting up additional satellite services doesn't work; docker-compose complains about not being able to extend services that use 'depends_on'. Looks like it's a potentially known issue, but not sure anything is going to be done about it: services with 'depends_on' cannot be extended · Issue #3220 · docker/compose · GitHub

I was ultimately able to add the following to my docker-compose.override.yml to spin up a second satellite service; leaving here in case this helps others.

    image: 'quantrocket/satellite:2.5.0'
      - 'codeload:/codeload'
      - 'db:/var/lib/quantrocket'
      - codeload
    restart: always

Thank you, we will update the docs.
