Hey Tim, ya the instructions look good thanks! I was wondering if we could use docker compose build and docker compose up commands instead though, then the port will be loaded from the .env and then the client could also use that same variable

What's the benefit of running the ad service locally?

This PR is adding instructions to use the ad service's client that was included from the google repository.
It's used to make direct requests to the service without setting up the whole project.

We have other similar clients
