title: Can I synchronize or mirror dependencies from packagist.org with my own Composer Satis installation?
body: <p>We have our own Satis repository, we can store there our own dependencies. This works fine.</p>
  
  <p>But if a developer uses a package that is not within in our own repository, then Composer will fetch it from GitHub through packagist.org (as a fallback). </p>
  
  <p>But we do not want to be dependent on packagist.org. All dependencies should be downloaded from our own repository. </p>
  
  <p>What we like to know, if its possible that Satis download a package from Packagist, if it is not locally available yet, and then store it and add it to Satis own repository automatically . </p>
  
  <p>This way we do not have to manually add the dependencies to the Satis repository.</p>
