title: Azure DevOps: Why does new pipeline commit the yaml file to default branch
body: <p>I created a new pipeline in Azure DevOps, and created a new branch for it.</p>
  
  <p>As a result, DevOps automatically committed the YAML file for the new pipeline to my 'development' branch.</p>
  
  <p>None of the other pipelines I've created have YAML files committed into the repo...</p>
  
  <p>Why does it do this?</p>
  
  <p>Do we have to keep the YAML file there?</p>
  
  <p>It has nothing to do with the source code of the application, so doesn't seem to make sense why its stored there.</p>
