        Hydra lets you focus on the problem at hand instead of spending time on boilerplate code like command line flags, loading configuration files, logging etc.

        With Hydra, you can compose your configuration dynamically, enabling you to easily
        get the perfect configuration for each run.
        You can override everything from the command line, which makes experimentation fast, and removes the need to maintain multiple similar configuration files.

          Hydra has a pluggable architecture, enabling it to integrate with your infrastructure.
          Future plugins will enable launching your code on AWS or other cloud providers directly from the command line.
