 ## Docker Compose
 
 A `docker-compose.yml` is also provided to get pinger started more easier.
-Just add an `agent.yml` according to your use case, replace
-`CMD [ "./pinger", "version" ]` in the `Dockerfile` with `CMD [ "./pinger", "agent" ]`
+Just add an `agent.yml` according to your use case (or Run `cp agent.sample.yml agent.yml`)
 and then run `docker-compose up`.
 This will get both the timescale db and pinger container up and running in no time!
