body: <p>I am quite new in typo3. I read somewhere </p>
  
  <p><code>You should never edit the original templates of an extension as those changes will vanish if you upgrade the extension</code></p>
  
  <p>How to create my own custom template based on bootstrap_package extension? I would like to override some files in parital/layout. It would be great if someone can post like/tutorial. 
  A folder structure and a simple custom typoscript that implement bootstrap_package for my custom temple would be great help. </p>
