  + # In CircleCI, each step runs in a new shell. The way to share ENV variables across steps is to export them from
  + # `$BASH_ENV`, which is automatically sourced at the beginning of every step (for the default `bash` shell).
  + #
  + # See also https://circleci.com/docs/2.0/env-vars/#using-bash_env-to-set-environment-variables.
  + #
  + # NOTE:
  + # Using `tee -a` prints the values to stdout, which can help with debugging.
  + # Secrets (e.g. passwords, access token) should NOT be printed.
