  <p>
    NNI provides CommandLine Tool as well as an user friendly WebUI to manage training experiements.
    With the extensible API, you can customize your own AutoML algorithms and training services.
    To make it easy for new users, NNI also provides a set of build-in stat-of-the-art
    AutoML algorithms and out of box support for popular training platforms.
  </p>
  <p>
    Within the following table, we summarized the current NNI capabilities,
    we are gradually adding new capabilities and we'd love to have your contribution.
