  The default installation provides a test user register with email <code>testuser@rosetta.platform</code>
  and password <code>testpass</code>, which you can use to login on the menu on the right or using the link
  below and give Rosetta a try immediately. If you run with the default docker-compose file (i.e. you just
  run <code>rosetta/setup</code>), then you will also have a few demo computing resources you can play with
  out-of-the-box, including a small Slurm cluster. Otherwise, you will need to setup your own computing
  resources either platform-wide or as user.
