Newbie questions

Currently I have one project ( labspl/forem ) connected to CircleCI and it build ok.
Everytime I commit sth, CCI grabs last commit and ( tries to ) builds it.

Now:

  • CCI uses credits: how much credit(s) is used per onebuild-action?
  • how to edit pipeline’s name? Does it have to be hello-world? DONE

please share config.yml
