difference between freestyle project and pipeline in jenkins : <p>I'm a little confused about Freestyle project and pipeline in jenkins when trying to create new items.</p>

<p>When should I create item with Freestyle project? And in which case should I use pipeline?</p>

<p>Do I need to store config.xml into code repository for future import? Or any other usage?</p>

<p>Thanks for your help.</p>
