anchor.diff:  ```yml
   - group: "\:broom\: Linting"
     key: "linting"
  -  depends_on: docker
     steps:
       - name: "\:rubocop\: RuboCop"
         command: ".buildkite/steps/rubocop"
  
positive.code:   steps:
      - command: "buildkite agent pipeline upload"
  ```
  {: codeblock-file="pipeline-01.yml"}
  
  And this YAML file uploads a pipeline that has a group with the same name:
  
  
negative.code:   steps:
      - command: "docker build"
  ```
  {: codeblock-file="pipeline.yml"}  
  
  As a result, the groups will be merged into one in the UI, and the `"docker build"` step will be added to the existing group.
