   These groups will be merged into one in the UI, and the `"docker build"` step will be added to the existing group.

  ## Group merging  
  
  Different groups that have the same `group` name or `label` and are defined consecutively in the pipeline will be merged together in the Buildkite UI.

  Running jobs in parallel has some limitations:
  
  <!-- vale off -->
  * If you put a command between consecutive groups in a YAML config, the groups will no longer be interpreted as parallel.
