Navigator provides a convenient graphical interface for managing conda
environments, channels and packages. But if you're comfortable working
with Anaconda Prompt or a terminal window, you can access additional, 
advanced management features. To learn more, see
`Managing packages <https://conda.io/docs/using/pkgs.html>`_ with
