No full sample buildarr.yml included in docs

[ssbarnea]

I was looking to try build but I was surprised to discover that there is no single file named buildarr.yml on entire github based on https://sourcegraph.com/search?q=context:global+file:buildarr.yml&patternType=keyword&sm=0

Not having a sample file to try makes it much hard to understand the benefits of using it. I tried the minimal example from https://buildarr.github.io/ just to discover that that is not functional at all because when I used buildarr compose to produce a compose file, I discovered that it generates an unexpected volume mount for buildarr itself, one that seems to hardcoded as the current directory:

  buildarr:
    volumes:
    - type: bind
      source: /Volumes/appdata/buildarr

That means that I cannot build the compose file on a machine (my laptop) in order to use it on another (my unraid NAS server).
